# Fixed IP addresses can also be specified for hosts. These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP. Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.

# based on that. The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all

# WELCOME TO SQUID 2.7.STABLE3
# ----------------------------
#
# This is the default Squid configuration file. You may wish
# to look at the Squid home page (http://www.squid-cache.org/)
# for the FAQ and other documentation.
#
# The default Squid config file shows what the defaults for
# various options happen to be. If you don't need to change the
# default, you shouldn't uncomment the line. Doing so may cause
# run-time problems. In some cases "none" refers to no default
# setting at all, while in other cases it refers to a valid
# option - the comments for that keyword indicate if this is the
# case.
#
# Configuration options can be included using the "include" directive.
# Include takes a list of files to include. Quoting and wildcards is
# supported.
#
# For example,
#
# include /path/to/included/file/squid.acl.config
#
# Includes can be nested up to a hard-coded depth of 16 levels.
# This arbitrary restriction is to prevent recursive include references
# from causing Squid entering an infinite loop whilst trying to load
# configuration files.
# OPTIONS FOR AUTHENTICATION
# -----------------------------------------------------------------------------
# TAG: auth_param
# This is used to define parameters for the various authentication
# schemes supported by Squid.
#
# format: auth_param scheme parameter [setting]
#
# The order in which authentication schemes are presented to the client is
# dependent on the order the scheme first appears in config file. IE
# has a bug (it's not RFC 2617 compliant) in that it will use the basic
# scheme if basic is the first entry presented, even if more secure
# schemes are presented. For now use the order in the recommended
# settings section below. If other browsers have difficulties (don't
# recognize the schemes offered even if you are using basic) either
# put basic first, or disable the other schemes (by commenting out their
# program entry).
#
# Once an authentication scheme is fully configured, it can only be
# shutdown by shutting squid down and restarting. Changes can be made on
# the fly and activated with a reconfigure. I.E. You can change to a
# different helper, but not unconfigure the helper completely.
#
# Please note that while this directive defines how Squid processes
# authentication it does not automatically activate authentication.
# To use authentication you must in addition make use of ACLs based
# on login name in http_access (proxy_auth, proxy_auth_regex or
# external with %LOGIN used in the format tag). The browser will be
# challenged for authentication on the first such acl encountered
# in http_access processing and will also be re-challenged for new
# login credentials if the request is being denied by a proxy_auth
# type acl.
#
# WARNING: authentication can't be used in a transparently intercepting
# proxy as the client then thinks it is talking to an origin server and
# not the proxy. This is a limitation of bending the TCP/IP protocol to
# transparently intercepting port 80, not a limitation in Squid.
#
# === Parameters for the basic scheme follow. ===
#
# "program" cmdline
# Specify the command for the external authenticator. Such a program
# reads a line containing "username password" and replies "OK" or
# "ERR" in an endless loop. "ERR" responses may optionally be followed
# by a error description available as %m in the returned error page.
#
# By default, the basic authentication scheme is not used unless a
# program is specified.
#
# If you want to use the traditional proxy authentication, jump over to
# the helpers/basic_auth/NCSA directory and type:
# % make
# % make install
#
# Then, set this line to something like
#
# auth_param basic program /usr/lib/squid/ncsa_auth /usr/etc/passwd
#
# "children" numberofchildren
# The number of authenticator processes to spawn. If you start too few
# squid will have to wait for them to process a backlog of credential
# verifications, slowing it down. When credential verifications are
# done via a (slow) network you are likely to need lots of
# authenticator processes.
# auth_param basic children 5
#
# "concurrency" numberofconcurrentrequests
# The number of concurrent requests/channels the helper supports.
# Changes the protocol used to include a channel number first on
# the request/response line, allowing multiple requests to be sent
# to the same helper in parallell without wating for the response.
# Must not be set unless it's known the helper supports this.
#
# "realm" realmstring
# Specifies the realm name which is to be reported to the client for
# the basic proxy authentication scheme (part of the text the user
# will see when prompted their username and password).
# auth_param basic realm Squid proxy-caching web server
#
# "credentialsttl" timetolive
# Specifies how long squid assumes an externally validated
# username:password pair is valid for - in other words how often the
# helper program is called for that user. Set this low to force
# revalidation with short lived passwords. Note that setting this high
# does not impact your susceptibility to replay attacks unless you are
# using an one-time password system (such as SecureID). If you are using
# such a system, you will be vulnerable to replay attacks unless you
# also use the max_user_ip ACL in an http_access rule.
# auth_param basic credentialsttl 2 hours
#
# "casesensitive" on|off
# Specifies if usernames are case sensitive. Most user databases are
# case insensitive allowing the same username to be spelled using both
# lower and upper case letters, but some are case sensitive. This
# makes a big difference for user_max_ip ACL processing and similar.
# auth_param basic casesensitive off
#
# "blankpassword" on|off
# Specifies if blank passwords should be supported. Defaults to off
# as there is multiple authentication backends which handles blank
# passwords as "guest" access.
#
# === Parameters for the digest scheme follow ===
#
# "program" cmdline
# Specify the command for the external authenticator. Such a program
# reads a line containing "username":"realm" and replies with the
# appropriate H(A1) value hex encoded or ERR if the user (or his H(A1)
# hash) does not exists. See RFC 2616 for the definition of H(A1).
# "ERR" responses may optionally be followed by a error description
# available as %m in the returned error page.
#
# By default, the digest authentication scheme is not used unless a
# program is specified.
#
# If you want to use a digest authenticator, jump over to the
# helpers/digest_auth/ directory and choose the authenticator to use.
# It it's directory type
# % make
# % make install
#
# Then, set this line to something like
#
# auth_param digest program /usr/lib/squid/digest_auth_pw /usr/etc/digpass
#
# "children" numberofchildren
# The number of authenticator processes to spawn. If you start too few
# squid will have to wait for them to process a backlog of credential
# verifications, slowing it down. When credential verifications are
# done via a (slow) network you are likely to need lots of
# authenticator processes.
# auth_param digest children 5
#
# "concurrency" numberofconcurrentrequests
# The number of concurrent requests/channels the helper supports.
# Changes the protocol used to include a channel number first on
# the request/response line, allowing multiple requests to be sent
# to the same helper in parallell without wating for the response.
# Must not be set unless it's known the helper supports this.
#
# "realm" realmstring
# Specifies the realm name which is to be reported to the client for the
# digest proxy authentication scheme (part of the text the user will see
# when prompted their username and password).
# auth_param digest realm Squid proxy-caching web server
#
# "nonce_garbage_interval" timeinterval
# Specifies the interval that nonces that have been issued to clients are
# checked for validity.
# auth_param digest nonce_garbage_interval 5 minutes
#
# "nonce_max_duration" timeinterval
# Specifies the maximum length of time a given nonce will be valid for.
# auth_param digest nonce_max_duration 30 minutes
#
# "nonce_max_count" number
# Specifies the maximum number of times a given nonce can be used.
# auth_param digest nonce_max_count 50
#
# "nonce_strictness" on|off
# Determines if squid requires strict increment-by-1 behavior for nonce
# counts, or just incrementing (off - for use when useragents generate
# nonce counts that occasionally miss 1 (ie, 1,2,4,6)).
# auth_param digest nonce_strictness off
#
# "check_nonce_count" on|off
# This directive if set to off can disable the nonce count check
# completely to work around buggy digest qop implementations in certain
# mainstream browser versions. Default on to check the nonce count to
# protect from authentication replay attacks.
# auth_param digest check_nonce_count on
#
# "post_workaround" on|off
# This is a workaround to certain buggy browsers who sends an incorrect
# request digest in POST requests when reusing the same nonce as acquired
# earlier in response to a GET request.
# auth_param digest post_workaround off
#
# === NTLM scheme options follow ===
#
# "program" cmdline
# Specify the command for the external NTLM authenticator. Such a
# program participates in the NTLMSSP exchanges between Squid and the
# client and reads commands according to the Squid NTLMSSP helper
# protocol. See helpers/ntlm_auth/ for details. Recommended ntlm
# authenticator is ntlm_auth from Samba-3.X, but a number of other
# ntlm authenticators is available.
#
# By default, the ntlm authentication scheme is not used unless a
# program is specified.
#
# auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
#
# "children" numberofchildren
# The number of authenticator processes to spawn. If you start too few
# squid will have to wait for them to process a backlog of credential
# verifications, slowing it down. When credential verifications are
# done via a (slow) network you are likely to need lots of
# authenticator processes.
# auth_param ntlm children 5
#
# "keep_alive" on|off
# This option enables the use of keep-alive on the initial
# authentication request. It has been reported some versions of MSIE
# have problems if this is enabled, but performance will be increased
# if enabled.
#
# auth_param ntlm keep_alive on
#
# === Negotiate scheme options follow ===
#
# "program" cmdline
# Specify the command for the external Negotiate authenticator. Such a
# program participates in the SPNEGO exchanges between Squid and the
# client and reads commands according to the Squid ntlmssp helper
# protocol. See helpers/ntlm_auth/ for details. Recommended SPNEGO
# authenticator is ntlm_auth from Samba-4.X.
#
# By default, the Negotiate authentication scheme is not used unless a
# program is specified.
#
# auth_param negotiate program /path/to/samba/bin/ntlm_auth --helper-protocol=gss-spnego
#
# "children" numberofchildren
# The number of authenticator processes to spawn. If you start too few
# squid will have to wait for them to process a backlog of credential
# verifications, slowing it down. When credential verifications are
# done via a (slow) network you are likely to need lots of
# authenticator processes.
# auth_param negotiate children 5
#
# "keep_alive" on|off
# If you experience problems with PUT/POST requests when using the
# Negotiate authentication scheme then you can try setting this to
# off. This will cause Squid to forcibly close the connection on
# the initial requests where the browser asks which schemes are
# supported by the proxy.
#
# auth_param negotiate keep_alive on
#
#Recommended minimum configuration per scheme:
#auth_param negotiate program <uncomment and complete this line to activate>
#auth_param negotiate children 5
#auth_param negotiate keep_alive on
#auth_param ntlm program <uncomment and complete this line to activate>
#auth_param ntlm children 5
#auth_param ntlm keep_alive on
#auth_param digest program <uncomment and complete this line>
#auth_param digest children 5
#auth_param digest realm Squid proxy-caching web server

# TAG: authenticate_cache_garbage_interval
# The time period between garbage collection across the username cache.
# This is a tradeoff between memory utilization (long intervals - say
# 2 days) and CPU (short intervals - say 1 minute). Only change if you
# have good reason to.
#
#Default:
# authenticate_cache_garbage_interval 1 hour
# TAG: authenticate_ttl
# The time a user & their credentials stay in the logged in user cache
# since their last request. When the garbage interval passes, all user
# credentials that have passed their TTL are removed from memory.
#
#Default:
# authenticate_ttl 1 hour
# TAG: authenticate_ip_ttl
# If you use proxy authentication and the 'max_user_ip' ACL, this
# directive controls how long Squid remembers the IP addresses
# associated with each user. Use a small value (e.g., 60 seconds) if
# your users might change addresses quickly, as is the case with
# dialups. You might be safe using a larger value (e.g., 2 hours) in a
# corporate LAN environment with relatively static address assignments.
#
#Default:
# authenticate_ip_ttl 0 seconds
# TAG: authenticate_ip_shortcircuit_ttl
# Cache authentication credentials per client IP address for this
# long. Default is 0 seconds (disabled).
#
#Default:
# authenticate_ip_shortcircuit_ttl 0 seconds
# ACCESS CONTROLS
# -----------------------------------------------------------------------------
# TAG: external_acl_type
# This option defines external acl classes using a helper program to
# look up the status
#
# external_acl_type name [options] FORMAT.. /path/to/helper [helper arguments..]
#
# Options:
#
# ttl=n TTL in seconds for cached results (defaults to 3600
# for 1 hour)
# negative_ttl=n
# TTL for cached negative lookups (default same
# as ttl)
# children=n number of processes spawn to service external acl
# lookups of this type. (default 5).
# concurrency=n concurrency level per process. Only used with helpers
# capable of processing more than one query at a time.
# Note: see compatibility note below
# cache=n result cache size, 0 is unbounded (default)
# grace= Percentage remaining of TTL where a refresh of a
# cached entry should be initiated without needing to
# wait for a new reply. (default 0 for no grace period)
# protocol=2.5 Compatibility mode for Squid-2.5 external acl helpers
#
# FORMAT specifications
#
# %LOGIN Authenticated user login name
# %EXT_USER Username from external acl
# %IDENT Ident user name
# %SRC Client IP
# %SRCPORT Client source port
# %URI Requested URI
# %DST Requested host
# %PROTO Requested protocol

# %USER_CERT SSL User certificate in PEM format
# %USER_CERTCHAIN SSL User certificate chain in PEM format
# %USER_CERT_xx SSL User certificate subject attribute xx
# %USER_CA_xx SSL User certificate issuer attribute xx
# %{Header} HTTP request header
# %{Hdr:member} HTTP request header list member
# %{Hdr:;member}
# HTTP request header list member using ; as
# list separator. ; can be any non-alphanumeric
# character.
# %ACL The ACL name
# %DATA The ACL arguments. If not used then any arguments
# is automatically added at the end
#
# In addition to the above, any string specified in the referencing
# acl will also be included in the helper request line, after the
# specified formats (see the "acl external" directive)
#
# The helper receives lines per the above format specification,
# and returns lines starting with OK or ERR indicating the validity
# of the request and optionally followed by additional keywords with
# more details.
#
# General result syntax:
#
# OK/ERR keyword=value ...
#
# Defined keywords:
#
# user= The users name (login also understood)
# password= The users password (for PROXYPASS login= cache_peer)
# message= Error message or similar used as %o in error messages
# (error also understood)
# log= String to be logged in access.log. Available as
# %ea in logformat specifications
#
# If protocol=3.0 (the default) then URL escaping is used to protect
# each value in both requests and responses.
#
# If using protocol=2.5 then all values need to be enclosed in quotes
# if they may contain whitespace, or the whitespace escaped using \.
# And quotes or \ characters within the keyword value must be \ escaped.
#
# When using the concurrency= option the protocol is changed by
# introducing a query channel tag infront of the request/response.
# The query channel tag is a number between 0 and concurrency-1.
#
# Compatibility Note: The children= option was named concurrency= in
# Squid-2.5.STABLE3 and earlier, and was accepted as an alias for the
# duration of the Squid-2.5 releases to keep compatibility. However,
# the meaning of concurrency= option has changed in Squid-2.6 to match
# that of Squid-3 and the old syntax no longer works.
#
#Default:
# none
# TAG: acl
# Defining an Access List
#
# Every access list definition must begin with an aclname and acltype,
# followed by either type-specific arguments or a quoted filename that
# they are read from.
#
# acl aclname acltype argument ...
# acl aclname acltype "file" ...
#
# when using "file", the file should contain one item per line.
#
# By default, regular expressions are CASE-SENSITIVE. To make
# them case-insensitive, use the -i option.
#
# acl aclname src ip-address/netmask ... (clients IP address)
# acl aclname src addr1-addr2/netmask ... (range of addresses)
# acl aclname dst ip-address/netmask ... (URL host's IP address)
# acl aclname myip ip-address/netmask ... (local socket IP address)
#
# acl aclname arp mac-address ... (xx:xx:xx:xx:xx:xx notation)
# # The arp ACL requires the special configure option --enable-arp-acl.
# # Furthermore, the arp ACL code is not portable to all operating systems.
# # It works on Linux, Solaris, FreeBSD and some other *BSD variants.
# #
# # NOTE: Squid can only determine the MAC address for clients that are on
# # the same subnet. If the client is on a different subnet, then Squid cannot
# # find out its MAC address.
#
# acl aclname srcdomain .foo.com ... # reverse lookup, client IP
# acl aclname dstdomain .foo.com ... # Destination server from URL
# acl aclname srcdom_regex [-i] xxx ... # regex matching client name
# acl aclname dstdom_regex [-i] xxx ... # regex matching server
# # For dstdomain and dstdom_regex a reverse lookup is tried if a IP
# # based URL is used and no match is found. The name "none" is used
# # if the reverse lookup fails.
#
# acl aclname time [day-abbrevs] [h1:m1-h2:m2]
# # day-abbrevs:
# # S - Sunday
# # M - Monday
# # T - Tuesday
# # W - Wednesday

# # A - Saturday
# # h1:m1 must be less than h2:m2
# acl aclname url_regex [-i] ^http:// ... # regex matching on whole URL
# acl aclname urlpath_regex [-i] \.gif$ ... # regex matching on URL path
# acl aclname urllogin [-i] [^a-zA-Z0-9] ... # regex matching on URL login field
# acl aclname port 80 70 21 ...
# acl aclname port 0-1024 ... # ranges allowed
# acl aclname myport 3128 ... # (local socket TCP port)
# acl aclname myportname 3128 ... # http(s)_port name
# acl aclname proto HTTP FTP ...
# acl aclname method GET POST ...
# acl aclname browser [-i] regexp ...
# # pattern match on User-Agent header (see also req_header below)
# acl aclname referer_regex [-i] regexp ...
# # pattern match on Referer header
# # Referer is highly unreliable, so use with care
# acl aclname ident username ...
# acl aclname ident_regex [-i] pattern ...
# # string match on ident output.
# # use REQUIRED to accept any non-null ident.
# acl aclname src_as number ...
# acl aclname dst_as number ...
# # Except for access control, AS numbers can be used for
# # routing of requests to specific caches. Here's an
# # example for routing all requests for AS#1241 and only
# # those to mycache.mydomain.net:
# # acl asexample dst_as 1241
# # cache_peer_access mycache.mydomain.net allow asexample
# # cache_peer_access mycache_mydomain.net deny all
#
# acl aclname proxy_auth [-i] username ...
# acl aclname proxy_auth_regex [-i] pattern ...
# # list of valid usernames
# # use REQUIRED to accept any valid username.
# #
# # NOTE: when a Proxy-Authentication header is sent but it is not
# # needed during ACL checking the username is NOT logged
# # in access.log.
# #
# # NOTE: proxy_auth requires a EXTERNAL authentication program
# # to check username/password combinations (see
# # auth_param directive).
# #
# # NOTE: proxy_auth can't be used in a transparent proxy as
# # the browser needs to be configured for using a proxy in order
# # to respond to proxy authentication.
#
# acl aclname snmp_community string ...
# # A community string to limit access to your SNMP Agent
# # Example:
# #
# # acl snmppublic snmp_community public
#
# acl aclname maxconn number
# # This will be matched when the client's IP address has
# # more than <number> HTTP connections established.
#
# acl aclname max_user_ip [-s] number
# # This will be matched when the user attempts to log in from more
# # than <number> different ip addresses. The authenticate_ip_ttl
# # parameter controls the timeout on the ip entries.
# # If -s is specified the limit is strict, denying browsing
# # from any further IP addresses until the ttl has expired. Without
# # -s Squid will just annoy the user by "randomly" denying requests.
# # (the counter is reset each time the limit is reached and a
# # request is denied)
# # NOTE: in acceleration mode or where there is mesh of child proxies,
# # clients may appear to come from multiple addresses if they are
# # going through proxy farms, so a limit of 1 may cause user problems.
#
# acl aclname req_mime_type mime-type ...
# # regex match against the mime type of the request generated
# # by the client. Can be used to detect file upload or some
# # types HTTP tunneling requests.
# # NOTE: This does NOT match the reply. You cannot use this
# # to match the returned file type.
#
# acl aclname req_header header-name [-i] any\.regex\.here
# # regex match against any of the known request headers. May be
# # thought of as a superset of "browser", "referer" and "mime-type"
# # ACLs.
#
# acl aclname rep_mime_type mime-type ...
# # regex match against the mime type of the reply received by
# # squid. Can be used to detect file download or some
# # types HTTP tunneling requests.
# # NOTE: This has no effect in http_access rules. It only has
# # effect in rules that affect the reply data stream such as
# # http_reply_access.
#
# acl aclname rep_header header-name [-i] any\.regex\.here
# # regex match against any of the known reply headers. May be
# # thought of as a superset of "browser", "referer" and "mime-type"
# # ACLs.
# #
# # Example:
# #
# # acl many_spaces rep_header Content-Disposition -i [[:space:]]{3,}
#
# acl aclname external class_name [arguments...]
# # external ACL lookup via a helper class defined by the
# # external_acl_type directive.
#
# acl aclname urlgroup group1 ...
# # match against the urlgroup as indicated by redirectors
#
# acl aclname user_cert attribute values...
# # match against attributes in a user SSL certificate
# # attribute is one of DN/C/O/CN/L/ST
#
# acl aclname ca_cert attribute values...
# # match against attributes a users issuing CA SSL certificate
# # attribute is one of DN/C/O/CN/L/ST
#
# acl aclname ext_user username ...
# acl aclname ext_user_regex [-i] pattern ...
# # string match on username returned by external acl helper
# # use REQUIRED to accept any non-null user name.
#
#Examples:
#acl macaddress arp 09:00:2b:23:45:67

# TAG: ident_lookup_access
# A list of ACL elements which, if matched, cause an ident
# (RFC931) lookup to be performed for this request. For
# example, you might choose to always perform ident lookups
# for your main multi-user Unix boxes, but not for your Macs
# and PCs. By default, ident lookups are not performed for
# any requests.
#
# To enable ident lookups for specific client addresses, you
# can follow this example:
#
# acl ident_aware_hosts src 198.168.1.0/255.255.255.0
# ident_lookup_access allow ident_aware_hosts
# ident_lookup_access deny all
#
# Only src type ACL checks are fully supported. A src_domain
# ACL might work at times, but it will not always provide
# the correct result.
#
#Default:
# ident_lookup_access deny all
# TAG: reply_body_max_size bytes allow|deny acl acl...
# This option specifies the maximum size of a reply body in bytes.
# It can be used to prevent users from downloading very large files,
# such as MP3's and movies. When the reply headers are received,
# the reply_body_max_size lines are processed, and the first line with
# a result of "allow" is used as the maximum body size for this reply.
# This size is checked twice. First when we get the reply headers,
# we check the content-length value. If the content length value exists
# and is larger than the allowed size, the request is denied and the
# user receives an error message that says "the request or reply
# is too large." If there is no content-length, and the reply
# size exceeds this limit, the client's connection is just closed
# and they will receive a partial reply.
#
# WARNING: downstream caches probably can not detect a partial reply
# if there is no content-length header, so they will cache
# partial responses and give them out as hits. You should NOT
# use this option if you have downstream caches.
#
# If you set this parameter to zero (the default), there will be
# no limit imposed.
#
#Default:
# reply_body_max_size 0 allow all
# TAG: authenticate_ip_shortcircuit_access
# Access list determining when shortcicuiting the authentication process
# based on source IP cached credentials is acceptable. Use this to deny
# using the ip auth cache on requests from child proxies or other source
# ip's having multiple users.
#
#Default:

# OPTIONS FOR X-Forwarded-For
# -----------------------------------------------------------------------------
# TAG: follow_x_forwarded_for
# Allowing or Denying the X-Forwarded-For header to be followed to
# find the original source of a request.
#
# Requests may pass through a chain of several other proxies
# before reaching us. The X-Forwarded-For header will contain a
# comma-separated list of the IP addresses in the chain, with the
# rightmost address being the most recent.
#
# If a request reaches us from a source that is allowed by this
# configuration item, then we consult the X-Forwarded-For header
# to see where that host received the request from. If the
# X-Forwarded-For header contains multiple addresses, and if
# acl_uses_indirect_client is on, then we continue backtracking
# until we reach an address for which we are not allowed to
# follow the X-Forwarded-For header, or until we reach the first
# address in the list. (If acl_uses_indirect_client is off, then
# it's impossible to backtrack through more than one level of
# X-Forwarded-For addresses.)
#
# The end result of this process is an IP address that we will
# refer to as the indirect client address. This address may
# be treated as the client address for access control, delay
# pools and logging, depending on the acl_uses_indirect_client,
# delay_pool_uses_indirect_client and log_uses_indirect_client
# options.
#
# SECURITY CONSIDERATIONS:
#
# Any host for which we follow the X-Forwarded-For header
# can place incorrect information in the header, and Squid
# will use the incorrect information as if it were the
# source address of the request. This may enable remote
# hosts to bypass any access control restrictions that are
# based on the client's source addresses.
#
# For example:
#
# acl localhost src 127.0.0.1
# acl my_other_proxy srcdomain .proxy.example.com
# follow_x_forwarded_for allow localhost
# follow_x_forwarded_for allow my_other_proxy
#
#Default:
# follow_x_forwarded_for deny all
# TAG: acl_uses_indirect_client on|off
# Controls whether the indirect client address
# (see follow_x_forwarded_for) is used instead of the
# direct client address in acl matching.
#
#Default:
# acl_uses_indirect_client on
# TAG: delay_pool_uses_indirect_client on|off
# Controls whether the indirect client address
# (see follow_x_forwarded_for) is used instead of the
# direct client address in delay pools.
#
#Default:
# delay_pool_uses_indirect_client on
# TAG: log_uses_indirect_client on|off
# Controls whether the indirect client address

# NETWORK OPTIONS
# -----------------------------------------------------------------------------
# TAG: http_port
# Usage: port [options]
# hostname:port [options]
# 1.2.3.4:port [options]
#
# The socket addresses where Squid will listen for HTTP client
# requests. You may specify multiple socket addresses.
# There are three forms: port alone, hostname with port, and
# IP address with port. If you specify a hostname or IP
# address, Squid binds the socket to that specific
# address. This replaces the old 'tcp_incoming_address'
# option. Most likely, you do not need to bind to a specific
# address, so you can use the port number alone.
#
# If you are running Squid in accelerator mode, you
# probably want to listen on port 80 also, or instead.
#
# The -I command line option will override the *first* port
# specified here.
#
# You may specify multiple socket addresses on multiple lines.
#
# Options:
#
# transparent Support for transparent interception of
# outgoing requests without browser settings.
#
# tproxy Support Linux TPROXY for spoofing outgoing
# connections using the client IP address.
#
# accel Accelerator mode. See also the related vhost,
# vport and defaultsite directives.
#
# defaultsite=domainname
# What to use for the Host: header if it is not present
# in a request. Determines what site (not origin server)
# accelerators should consider the default.
# Defaults to visible_hostname:port if not set
# May be combined with vport=NN to override the port number.
# Implies accel.
#
# vhost Accelerator mode using Host header for virtual
# domain support. Implies accel.
#
# vport Accelerator with IP based virtual host support.
# Implies accel.
#
# vport=NN As above, but uses specified port number rather
# than the http_port number. Implies accel.
#
# allow-direct Allow direct forwarding in accelerator mode. Normally
# accelerated requests is denied direct forwarding as it
# never_direct was used.
#
# urlgroup= Default urlgroup to mark requests with (see
# also acl urlgroup and url_rewrite_program)
#
# protocol= Protocol to reconstruct accelerated requests with.
# Defaults to http.
#
# no-connection-auth
# Prevent forwarding of Microsoft connection oriented
# authentication (NTLM, Negotiate and Kerberos)
#
# act-as-origin
# Act is if this Squid is the origin server.
# This currently means generate own Date: and
# Expires: headers. Implies accel.
#
# http11 Enables HTTP/1.1 support to clients. The HTTP/1.1
# support is still incomplete with an internal HTTP/1.0
# hop, but should work with most clients. The main
# HTTP/1.1 features missing due to this is forwarding
# of requests using chunked transfer encoding (results
# in 411) and forwarding of 1xx responses (silently
# dropped)
#
# name= Specifies a internal name for the port. Defaults to
# the port specification (port or addr:port)
#
# keepalive[=idle,interval,timeout]
# Enable TCP keepalive probes of idle connections
# idle is the initial time before TCP starts probing
# the connection, interval how often to probe, and
# timeout the time before giving up.
#
# If you run Squid on a dual-homed machine with an internal
# and an external interface we recommend you to specify the

#
# use 'proxy-only' to specify objects fetched
# from this cache should not be saved locally.
#
# use 'weight=n' to affect the selection of a peer
# during any weighted peer-selection mechanisms.
# The weight must be an integer; default is 1,
# larger weights are favored more.
# This option does not affect parent selection if a peering
# protocol is not in use.
#
# use 'ttl=n' to specify a IP multicast TTL to use
# when sending an ICP queries to this address.
# Only useful when sending to a multicast group.
# Because we don't accept ICP replies from random
# hosts, you must configure other group members as
# peers with the 'multicast-responder' option below.
#
# use 'no-query' to NOT send ICP queries to this
# neighbor.
#
# use 'default' if this is a parent cache which can
# be used as a "last-resort" if a peer cannot be located
# by any of the peer-selection mechanisms.
# If specified more than once, only the first is used.
#
# use 'round-robin' to define a set of parents which
# should be used in a round-robin fashion in the
# absence of any ICP queries.
#
# use 'carp' to define a set of parents which should
# be used as a CARP array. The requests will be
# distributed among the parents based on the CARP load
# balancing hash function based on their weight.
#
# 'multicast-responder' indicates the named peer
# is a member of a multicast group. ICP queries will
# not be sent directly to the peer, but ICP replies
# will be accepted from it.
#
# the 'multicast-siblings' option is meant to be used
# only for cache peers of type "multicast". It instructs
# Squid that ALL members of this multicast group have
# "sibling" relationship with it, not "parent". This is
# an optimization that avoids useless multicast queries
# to a multicast group when the requested object would
# be fetched only from a "parent" cache, anyway. It's
# useful, e.g., when configuring a pool of redundant
# Squid proxies, being members of the same
# multicast group.
#
# 'closest-only' indicates that, for ICP_OP_MISS
# replies, we'll only forward CLOSEST_PARENT_MISSes
# and never FIRST_PARENT_MISSes.
#
# use 'no-digest' to NOT request cache digests from
# this neighbor.
#
# 'no-netdb-exchange' disables requesting ICMP
# RTT database (NetDB) from the neighbor.
#
# use 'no-delay' to prevent access to this neighbor
# from influencing the delay pools.
#
# use 'login=user:password' if this is a personal/workgroup
# proxy and your parent requires proxy authentication.
# Note: The string can include URL escapes (i.e. %20 for
# spaces). This also means % must be written as %%.
#
# use 'login=PASS' if users must authenticate against
# the upstream proxy or in the case of a reverse proxy
# configuration, the origin web server. This will pass
# the users credentials as they are to the peer.
# Note: To combine this with local authentication the Basic
# authentication scheme must be used, and both servers must
# share the same user database as HTTP only allows for
# a single login (one for proxy, one for origin server).
# Also be warned this will expose your users proxy
# password to the peer. USE WITH CAUTION
#
# use 'login=*:password' to pass the username to the
# upstream cache, but with a fixed password. This is meant
# to be used when the peer is in another administrative
# domain, but it is still needed to identify each user.
# The star can optionally be followed by some extra
# information which is added to the username. This can
# be used to identify this proxy to the peer, similar to
# the login=username:password option above.
#
# use 'connect-timeout=nn' to specify a peer
# specific connect timeout (also see the
# peer_connect_timeout directive)
#
# use 'digest-url=url' to tell Squid to fetch the cache
# digest (if digests are enabled) for this host from
# the specified URL rather than the Squid default
# location.
#
# use 'allow-miss' to disable Squid's use of only-if-cached
# when forwarding requests to siblings. This is primarily
# useful when icp_hit_stale is used by the sibling. To
# extensive use of this option may result in forwarding
# loops, and you should avoid having two-way peerings
# with this option. (for example to deny peer usage on
# requests from peer by denying cache_peer_access if the
# source is a peer)
#
# use 'max-conn=n' to limit the amount of connections Squid
# may open to this peer.
#
# use 'htcp' to send HTCP, instead of ICP, queries
# to the neighbor. You probably also want to
# set the "icp port" to 4827 instead of 3130.
# You must also allow this Squid htcp_access and
# http_access in the peer Squid configuration.
#
# use 'htcp-oldsquid' to send HTCP to old Squid versions
# You must also allow this Squid htcp_access and
# http_access in the peer Squid configuration.
#
# 'originserver' causes this parent peer to be contacted as
# a origin server. Meant to be used in accelerator setups.
#
# use 'userhash' to load-balance amongst a set of parents
# based on the client proxy_auth or ident username.
#
# use 'sourcehash' to load-balance amongst a set of parents
# based on the client source ip.
#
# use 'name=xxx' if you have multiple peers on the same
# host but different ports. This name can be used to
# differentiate the peers in cache_peer_access and similar
# directives.
#
# use 'monitorurl=url' to have periodically request a given
# URL from the peer, and only consider the peer as alive
# if this monitoring is successful (default none)
#
# use 'monitorsize=min[-max]' to limit the size range of
# 'monitorurl' replies considered valid. Defaults to 0 to
# accept any size replies as valid.
#
# use 'monitorinterval=seconds' to change frequency of
# how often the peer is monitored with 'monitorurl'
# (default 300 for a 5 minute interval). If set to 0
# then monitoring is disabled even if a URL is defined.
#
# use 'monitortimeout=seconds' to change the timeout of
# 'monitorurl'. Defaults to 'monitorinterval'.
#
# use 'forceddomain=name' to forcibly set the Host header
# of requests forwarded to this peer. Useful in accelerator
# setups where the server (peer) expects a certain domain
# name and using redirectors to feed this domain name
# is not feasible.
#
# use 'ssl' to indicate connections to this peer should
# be SSL/TLS encrypted.
#
# use 'sslcert=/path/to/ssl/certificate' to specify a client
# SSL certificate to use when connecting to this peer.
#
# use 'sslkey=/path/to/ssl/key' to specify the private SSL
# key corresponding to sslcert above. If 'sslkey' is not
# specified 'sslcert' is assumed to reference a

#
# use sslversion=1|2|3|4 to specify the SSL version to use

# 1 = automatic (default)
# 2 = SSL v2 only
# 3 = SSL v3 only
# 4 = TLS v1 only
#
# use sslcipher=... to specify the list of valid SSL ciphers

# DONT_VERIFY_PEER
# Accept certificates even if they fail to
# verify.
# NO_DEFAULT_CA
# Don't use the default CA list built in
# to OpenSSL.
#
# use ssldomain= to specify the peer name as advertised

# of the received peer certificate. If not specified the
# peer hostname will be used.
#
# use front-end-https to enable the "Front-End-Https: On"
# header needed when using Squid as a SSL frontend in front

# on this header. If set to auto the header will
# only be added if the request is forwarded as a https://
# URL.
#
# use connection-auth=off to tell Squid that this peer does
# not support Microsoft connection oriented authentication,
# and any such challenges received from there should be
# ignored. Default is auto to automatically determine the

#
# use idle=n to specify a minimum number of idle connections
# that should be kept open to this peer.
#
# use http11 to send requests using HTTP/1.1 to this peer.
# Note: The HTTP/1.1 support is still incomplete, with an

# be forwarded.
#
#Default:
# none
# TAG: cache_peer_domain
# Use to limit the domains for which a neighbor cache will be
# queried. Usage:
#
# cache_peer_domain cache-host domain [domain ...]
# cache_peer_domain cache-host !domain
#
# For example, specifying
#
# cache_peer_domain parent.foo.net .edu
#
# has the effect such that UDP query packets are sent to
# 'bigserver' only when the requested object exists on a
# server in the .edu domain. Prefixing the domain name
# with '!' means the cache will be queried for objects
# NOT in that domain.
#
# NOTE: * Any number of domains may be given for a cache-host,
# either on the same or separate lines.
# * When multiple domains are given for a particular
# cache-host, the first matched domain is applied.
# * Cache hosts with no domain restrictions are queried
# for all requests.
# * There are no defaults.
# * There is also a 'cache_peer_access' tag in the ACL
# section.
#
#Default:
# none
# TAG: cache_peer_access
# Similar to 'cache_peer_domain' but provides more flexibility by
# using ACL elements.
#
# cache_peer_access cache-host allow|deny [!]aclname ...
#
# The syntax is identical to 'http_access' and the other lists of
# ACL elements. See the comments for 'http_access' below, or
# the Squid FAQ (http://www.squid-cache.org/FAQ/FAQ-10.html).
#
#Default:
# none
# TAG: neighbor_type_domain
# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
#
# Modifying the neighbor type for specific domains is now
# possible. You can treat some domains differently than the the
# default neighbor type specified on the 'cache_peer' line.
# Normally it should only be necessary to list domains which
# should be treated differently because the default neighbor type
# applies for hostnames which do not match domains listed here.
#
#EXAMPLE:
# cache_peer cache.foo.org parent 3128 3130
# neighbor_type_domain cache.foo.org sibling .com .net
# neighbor_type_domain cache.foo.org sibling .au .de
#
#Default:
# none
# TAG: dead_peer_timeout (seconds)
# This controls how long Squid waits to declare a peer cache
# as "dead." If there are no ICP replies received in this
# amount of time, Squid will declare the peer dead and not
# expect to receive any further ICP replies. However, it
# continues to send ICP queries, and will mark the peer as
# alive upon receipt of the first subsequent ICP reply.
#
# This timeout also affects when Squid expects to receive ICP
# replies from peers. If more than 'dead_peer' seconds have
# passed since the last ICP reply was received, Squid will not
# expect to receive an ICP reply on the next query. Thus, if
# your time between requests is greater than this timeout, you
# will see a lot of requests sent DIRECT to origin servers
# instead of to your parents.
#
#Default:
# dead_peer_timeout 10 seconds
# TAG: hierarchy_stoplist
# A list of words which, if found in a URL, cause the object to
# be handled directly by this cache. In other words, use this
# to not query neighbor caches for certain objects. You may
# list this option multiple times. Note: never_direct overrides
# this option.
#We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?
# MEMORY CACHE OPTIONS
# -----------------------------------------------------------------------------
# TAG: cache_mem (bytes)
# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
#
# 'cache_mem' specifies the ideal amount of memory to be used
# for:
# * In-Transit objects
# * Hot Objects
# * Negative-Cached objects
#
# Data for these objects are stored in 4 KB blocks. This
# parameter specifies the ideal upper limit on the total size of
# 4 KB blocks allocated. In-Transit objects take the highest
# priority.
#
# In-transit objects have priority over the others. When
# additional space is needed for incoming data, negative-cached
# and hot objects will be released. In other words, the
# negative-cached and hot objects will fill up any unused space
# not needed for in-transit objects.
#
# If circumstances require, this limit will be exceeded.
# Specifically, if your incoming request rate requires more than
# 'cache_mem' of memory to hold in-transit objects, Squid will
# exceed this limit to satisfy the new requests. When the load
# decreases, blocks will be freed until the high-water mark is
# reached. Thereafter, blocks will be used to store hot
# objects.
#
#Default:
# cache_mem 8 MB
# TAG: maximum_object_size_in_memory (bytes)
# Objects greater than this size will not be attempted to kept in
# the memory cache. This should be set high enough to keep objects
# accessed frequently in memory to improve performance whilst low
# enough to keep larger objects from hoarding cache_mem.
#
#Default:
# maximum_object_size_in_memory 8 KB
# TAG: memory_replacement_policy
# The memory replacement policy parameter determines which
# objects are purged from memory when memory space is needed.
#
# See cache_replacement_policy for details.
#
#Default:
# memory_replacement_policy lru
# DISK CACHE OPTIONS
# -----------------------------------------------------------------------------
# TAG: cache_replacement_policy
# The cache replacement policy parameter determines which
# objects are evicted (replaced) when disk space is needed.
#
# lru : Squid's original list based LRU policy
# heap GDSF : Greedy-Dual Size Frequency
# heap LFUDA: Least Frequently Used with Dynamic Aging
# heap LRU : LRU policy implemented using a heap
#
# Applies to any cache_dir lines listed below this.
#
# The LRU policies keeps recently referenced objects.
#
# The heap GDSF policy optimizes object hit rate by keeping smaller
# popular objects in cache so it has a better chance of getting a
# hit. It achieves a lower byte hit rate than LFUDA though since
# it evicts larger (possibly popular) objects.
#
# The heap LFUDA policy keeps popular objects in cache regardless of
# their size and thus optimizes byte hit rate at the expense of
# hit rate since one large, popular object will prevent many
# smaller, slightly less popular objects from being cached.
#
# Both policies utilize a dynamic aging mechanism that prevents
# cache pollution that can otherwise occur with frequency-based
# replacement policies.
#
# NOTE: if using the LFUDA replacement policy you should increase
# the value of maximum_object_size above its default of 4096 KB to
# to maximize the potential byte hit rate improvement of LFUDA.
#
# For more information about the GDSF and LFUDA cache replacement
# policies see http://www.hpl.hp.com/techreports/1999/HPL-1999-69.html
# and http://fog.hpl.external.hp.com/techreports/98/HPL-98-173.html.
#
#Default:
# cache_replacement_policy lru
# TAG: cache_dir
# Usage:
#
# cache_dir Type Directory-Name Fs-specific-data [options]
#
# You can specify multiple cache_dir lines to spread the
# cache among different disk partitions.
#
# Type specifies the kind of storage system to use. Only "ufs"
# is built by default. To enable any of the other storage systems
# see the --enable-storeio configure option.
#
# 'Directory' is a top-level directory where cache swap
# files will be stored. If you want to use an entire disk
# for caching, this can be the mount-point directory.
# The directory must exist and be writable by the Squid
# process. Squid will NOT create this directory for you.
# Only using COSS, a raw disk device or a stripe file can
# be specified, but the configuration of the "cache_swap_log"
# tag is mandatory.
#
# The ufs store type:
#
# "ufs" is the old well-known Squid storage format that has always
# been there.
#
# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
#
# 'Mbytes' is the amount of disk space (MB) to use under this
# directory. The default is 100 MB. Change this to suit your
# configuration. Do NOT put the size of your disk drive here.
# Instead, if you want Squid to use the entire disk drive,
# subtract 20% and use that value.
#
# 'Level-1' is the number of first-level subdirectories which
# will be created under the 'Directory'. The default is 16.
#
# 'Level-2' is the number of second-level subdirectories which
# will be created under each first-level directory. The default
# is 256.
#
# The aufs store type:
#
# "aufs" uses the same storage format as "ufs", utilizing
# POSIX-threads to avoid blocking the main Squid process on
# disk-I/O. This was formerly known in Squid as async-io.
#
# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
#
# see argument descriptions under ufs above
#
# The diskd store type:
#
# "diskd" uses the same storage format as "ufs", utilizing a
# separate process to avoid blocking the main Squid process on
# disk-I/O.
#
# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
#
# see argument descriptions under ufs above
#
# Q1 specifies the number of unacknowledged I/O requests when Squid
# stops opening new files. If this many messages are in the queues,
# Squid won't open new files. Default is 64
#
# Q2 specifies the number of unacknowledged messages when Squid
# starts blocking. If this many messages are in the queues,
# Squid blocks until it receives some replies. Default is 72
#
# When Q1 < Q2 (the default), the cache directory is optimized
# for lower response time at the expense of a decrease in hit
# ratio. If Q1 > Q2, the cache directory is optimized for
# higher hit ratio at the expense of an increase in response
# time.
#
# The coss store type:
#
# block-size=n defines the "block size" for COSS cache_dir's.
# Squid uses file numbers as block numbers. Since file numbers
# are limited to 24 bits, the block size determines the maximum
# size of the COSS partition. The default is 512 bytes, which
# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
# you should not change the COSS block size after Squid
# has written some objects to the cache_dir.
#
# overwrite-percent=n defines the percentage of disk that COSS
# must write to before a given object will be moved to the
# current stripe. A value of "n" closer to 100 will cause COSS
# to waste less disk space by having multiple copies of an object
# on disk, but will increase the chances of overwriting a popular
# object as COSS overwrites stripes. A value of "n" close to 0
# will cause COSS to keep all current objects in the current COSS
# stripe at the expense of the hit rate. The default value of 50
# will allow any given object to be stored on disk a maximum of
# 2 times.
#
# max-stripe-waste=n defines the maximum amount of space that COSS
# will waste in a given stripe (in bytes). When COSS writes data
# to disk, it will potentially waste up to "max-size" worth of disk
# space for each 1MB of data written. If "max-size" is set to a
# large value (ie >256k), this could potentially result in large
# amounts of wasted disk space. Setting this value to a lower value
# (ie 64k or 32k) will result in a COSS disk refusing to cache
# larger objects until the COSS stripe has been filled to within
# "max-stripe-waste" of the maximum size (1MB).
#
# membufs=n defines the number of "memory-only" stripes that COSS
# will use. When an cache hit is performed on a COSS stripe before
# COSS has reached the overwrite-percent value for that object,
# COSS will use a series of memory buffers to hold the object in
# while the data is sent to the client. This will define the maximum
# number of memory-only buffers that COSS will use. The default value
# is 10, which will use a maximum of 10MB of memory for buffers.
#
# maxfullbufs=n defines the maximum number of stripes a COSS partition
# will have in memory waiting to be freed (either because the disk is
# under load and the stripe is unwritten, or because clients are still
# transferring data from objects using the memory). In order to try
# and maintain a good hit rate under load, COSS will reserve the last
# 2 full stripes for object hits. (ie a COSS cache_dir will reject
# new objects when the number of full stripes is 2 less than maxfullbufs)
#
# The null store type:
#
# no options are allowed or required
#
# Common options:
#
# no-store, no new objects should be stored to this cache_dir
#
# min-size=n, refers to the min object size this storedir will accept.
# It's used to restrict a storedir to only store large objects
# (e.g. aufs) while other storedirs are optimized for smaller objects
# (e.g. COSS). Defaults to 0.
#
# max-size=n, refers to the max object size this storedir supports.
# It is used to initially choose the storedir to dump the object.
# Note: To make optimal use of the max-size limits you should order
# the cache_dir lines with the smallest max-size value first and the
# ones with no max-size specification last.
#
# Note that for coss, max-size must be less than COSS_MEMBUF_SZ
# (hard coded at 1 MB).

# TAG: store_dir_select_algorithm
# Set this to 'round-robin' as an alternative.
#
#Default:
# store_dir_select_algorithm least-load
# TAG: max_open_disk_fds
# To avoid having disk as the I/O bottleneck Squid can optionally
# bypass the on-disk cache if more than this amount of disk file
# descriptors are open.
#
# A value of 0 indicates no limit.
#
#Default:
# max_open_disk_fds 0
# TAG: minimum_object_size (bytes)
# Objects smaller than this size will NOT be saved on disk. The
# value is specified in kilobytes, and the default is 0 KB, which
# means there is no minimum.
#
#Default:
# minimum_object_size 0 KB
# TAG: maximum_object_size (bytes)
# Objects larger than this size will NOT be saved on disk. The
# value is specified in kilobytes, and the default is 4MB. If
# you wish to get a high BYTES hit ratio, you should probably
# increase this (one 32 MB object hit counts for 3200 10KB
# hits). If you wish to increase speed more than your want to
# save bandwidth you should leave this low.
#
# NOTE: if using the LFUDA replacement policy you should increase
# this value to maximize the byte hit rate improvement of LFUDA!
# See replacement_policy below for a discussion of this policy.
#
# NOTE 2: In Debian the default is raised to 20MB allowing cache
# of Packages files in debian repositories. This makes squid a
# proper proxy for APT.
#
#Default:
# maximum_object_size 20480 KB
# TAG: cache_swap_low (percent, 0-100)
# TAG: cache_swap_high (percent, 0-100)
#
# The low- and high-water marks for cache object replacement.
# Replacement begins when the swap (disk) usage is above the
# low-water mark and attempts to maintain utilization near the
# low-water mark. As swap utilization gets close to high-water
# mark object eviction becomes more aggressive. If utilization is
# close to the low-water mark less replacement is done each time.
#
# Defaults are 90% and 95%. If you have a large cache, 5% could be
# hundreds of MB. If this is the case you may wish to set these
# numbers closer together.
#
#Default:
# cache_swap_low 90
# cache_swap_high 95
# TAG: update_headers on|off
# By default Squid updates stored HTTP headers when receiving

# The <format specification> is a string with embedded % format codes
#
# % format codes all follow the same basic structure where all but

# access_log none [acl acl ...]]
#
# Will log to the specified file using the specified format (which

access_log /var/log/squid/access.log squid
# TAG: log_access allow|deny acl acl...
# This options allows you to control which requests gets logged

# TAG: logfile_daemon
# Specify the path to the logfile-writing daemon. This daemon is

#
#Default:
# logfile_daemon /usr/lib/squid/logfile-daemon
# TAG: cache_log
# Cache logging file. This is where general information about

# logged to this file with the "debug_options" tag below.
#
#Default:
# cache_log /var/log/squid/cache.log
# TAG: cache_store_log
# Logs the activities of the storage manager. Shows which
# objects are ejected from the cache, and which objects are
# saved and for how long. To disable, enter "none". There are
# not really utilities to analyze this data, so you can safely
# disable it.
#
#Default:
# cache_store_log /var/log/squid/store.log
# TAG: cache_swap_state
# Location for the cache "swap.state" file. This index file holds
# the metadata of objects saved on disk. It is used to rebuild
# the cache during startup. Normally this file resides in each
# 'cache_dir' directory, but you may specify an alternate
# pathname here. Note you must give a full filename, not just
# a directory. Since this is the index for the whole object
# list you CANNOT periodically rotate it!
#
# If %s can be used in the file name it will be replaced with a
# a representation of the cache_dir name where each / is replaced
# with '.'. This is needed to allow adding/removing cache_dir
# lines when cache_swap_log is being used.
#
# If have more than one 'cache_dir', and %s is not used in the name
# these swap logs will have names such as:
#
# cache_swap_log.00
# cache_swap_log.01
# cache_swap_log.02
#
# The numbered extension (which is added automatically)
# corresponds to the order of the 'cache_dir' lines in this
# configuration file. If you change the order of the 'cache_dir'
# lines in this file, these index files will NOT correspond to
# the correct 'cache_dir' entry (unless you manually rename
# them). We recommend you do NOT use this option. It is
# better to keep these index files in each 'cache_dir' directory.
#
#Default:
# none
# TAG: logfile_rotate
# Specifies the number of logfile rotations to make when you
# type 'squid -k rotate'. The default is 10, which will rotate
# with extensions 0 through 9. Setting logfile_rotate to 0 will
# disable the file name rotation, but the logfiles are still closed
# and re-opened. This will enable you to rename the logfiles
# yourself just before sending the rotate signal.
#
# Note, the 'squid -k rotate' command normally sends a USR1
# signal to the running squid process. In certain situations
# (e.g. on Linux with Async I/O), USR1 is used for other
# purposes, so -k rotate uses another signal. It is best to get
# in the habit of using 'squid -k rotate' instead of 'kill -USR1
# <pid>'.
#
# Note2, for Debian/Linux the default of logfile_rotate is
# zero, since it includes external logfile-rotation methods.
#
#Default:
# logfile_rotate 0
# TAG: emulate_httpd_log on|off
# The Cache can emulate the log file format which many 'httpd'
# programs use. To disable/enable this emulation, set
# emulate_httpd_log to 'off' or 'on'. The default
# is to use the native log format since it includes useful
# information Squid-specific log analyzers use.
#
#Default:
# emulate_httpd_log off
# TAG: log_ip_on_direct on|off
# Log the destination IP address in the hierarchy log tag when going
# direct. Earlier Squid versions logged the hostname here. If you
# prefer the old way set this to off.
#
#Default:
# log_ip_on_direct on
# TAG: mime_table
# Pathname to Squid's MIME table. You shouldn't need to change
# this, but the default file contains examples and formatting
# information if you do.
#
#Default:
# mime_table /usr/share/squid/mime.conf
# TAG: log_mime_hdrs on|off
# The Cache can record both the request and the response MIME
# headers for each HTTP transaction. The headers are encoded
# safely and will appear as two bracketed fields at the end of
# the access log (for either the native or httpd-emulated log
# formats). To enable this logging set log_mime_hdrs to 'on'.
#

# If you want the anonymous login password to be more informative
# (and enable the use of picky ftp servers), set this to something
# reasonable for your domain, like wwwuser@somewhere.net
#
# The reason why this is domainless by default is the
# request can be made on the behalf of a user in any domain,
# depending on how the cache is used.
# Some ftp server also validate the email address is valid
# (for example perl.com).
#
#Default:

# the FTP protocol.
#
# If you have trouble accessing files with ASCII code 255 in the
# path or similar problems involving this ASCII code you can

# OPTIONS FOR URL REWRITING
# -----------------------------------------------------------------------------
# TAG: storeurl_rewrite_program
# Specify the location of the executable for the Store URL rewriter.
# The Store URL rewriter allows URLs to be "normalised" ; mapping
# multiple URLs to a single URL representation for cache operations.
#
# For example, if you request an object at:
#
# http://srv1.example.com/image.gif
#
# and a subsequent request for:
#
# http://srv2.example.com/image.gif
#
# then Squid will treat these both as different URLs and cache them
# seperately.
#
# This is almost the normal case, but an increasing number of sites
# distribute the same content between multiple frontend hosts.
# The Store URL rewriter allows you to rewrite these URLs to one URL
# to use for cache operations, but not -fetches-. Fetches are still
# made from the original site, but stored with the store URL rewritten
# URL as the store key.
#
# For each requested URL rewriter will receive on line with the format
#
# URL <SP> client_ip "/" fqdn <SP> user <SP> method <SP> urlgroup
# [<SP> kvpairs] <NL>
#
# In the future, the rewriter interface will be extended with
# key=value pairs ("kvpairs" shown above). Rewriter programs
# should be prepared to receive and possibly ignore additional
# whitespace-separated tokens on each input line.
#
# And the rewriter may return a rewritten URL. The other components of
# the request line does not need to be returned (ignored if they are).
#
# By default, a Store URL rewriter is not used.
#
# Please note - the normal URL rewriter rewrites Squid's _destination_
# URL - ie, what it fetches. The Store URL rewriter rewrites Squid's
# _store_ URL - ie, what it uses to store and retrieve objects.

# TAG: url_rewrite_program
# Specify the location of the executable for the URL rewriter.
# Since they can perform almost any function there isn't one included.
#
# For each requested URL rewriter will receive on line with the format

#
# In the future, the rewriter interface will be extended with

# whitespace-separated tokens on each input line.
#
# And the rewriter may return a rewritten URL. The other components of
# the request line does not need to be returned (ignored if they are).
#
# The rewriter can also indicate that a client-side redirect should
# be performed to the new URL. This is done by prefixing the returned
# URL with "301:" (moved permanently) or 302: (moved temporarily).
#
# It can also return a "urlgroup" that can subsequently be matched
# in cache_peer_access and similar ACL driven rules. An urlgroup is
# returned by prefixing the returned URL with "!urlgroup!".

# By default, a URL rewriter is not used.
#
#Default:
# none
# TAG: url_rewrite_children
# The number of redirector processes to spawn. If you start

#
#Default:
# url_rewrite_children 5
# TAG: url_rewrite_concurrency
# The number of requests each redirector helper can handle in

# is a old-style single threaded redirector.
#
# When this directive is set to a value >= 1 then the protocol
# used to communicate with the helper is modified to include
# a request ID in front of the request/response. The request
# ID from the request must be echoed back with the response
# to that request.
#
#Default:
# url_rewrite_concurrency 0
# TAG: url_rewrite_host_header
# By default Squid rewrites any Host: header in redirected
# requests. If you are running an accelerator this may
# not be a wanted effect of a redirector.

# TAG: redirector_bypass
# When this is 'on', a request will not go through the
# redirector if all redirectors are busy. If this is 'off'
# and the redirector queue grows too large, Squid will exit
# with a FATAL error and ask you to increase the number of
# redirectors. You should only enable this if the redirectors
# are not critical to your caching system. If you use
# redirectors for access control, and you enable this option,
# users may have access to pages they should not
# be allowed to request.
#
#Default:

# TAG: location_rewrite_program
# Specify the location of the executable for the Location rewriter,
# used to rewrite server generated redirects. Usually used in
# conjunction with a url_rewrite_program
#
# For each Location header received the location rewriter will receive
# one line with the format:
#
# location URL <SP> requested URL <SP> urlgroup <NL>
#
# And the rewriter may return a rewritten Location URL or a blank line.
# The other components of the request line does not need to be returned
# (ignored if they are).
#
# By default, a Location rewriter is not used.
#
#Default:

#
#Default:
# location_rewrite_children 5
# TAG: location_rewrite_concurrency
# The number of requests each Location rewriter helper can handle in

# OPTIONS FOR TUNING THE CACHE
# -----------------------------------------------------------------------------
# TAG: cache
# A list of ACL elements which, if matched, cause the request to
# not be satisfied from the cache and the reply to not be cached.
# In other words, use this to force certain objects to never be cached.
#
# You must use the word 'DENY' to indicate the ACL names which should
# NOT be cached.
#
# Default is to allow all to be cached.
#
#Default:

# TAG: max_stale time-units
# This option puts an upper limit on how stale content Squid
# will serve from the cache if cache validation fails.
#
#Default:
# max_stale 1 week
# TAG: refresh_pattern
# usage: refresh_pattern [-i] regex min percent max [options]
#
# By default, regular expressions are CASE-SENSITIVE. To make
# them case-insensitive, use the -i option.
#
# 'Min' is the time (in minutes) an object without an explicit
# expiry time should be considered fresh. The recommended
# value is 0, any higher values may cause dynamic applications
# to be erroneously cached unless the application designer
# has taken the appropriate actions.
#
# 'Percent' is a percentage of the objects age (time since last
# modification age) an object without explicit expiry time
# will be considered fresh.
#
# 'Max' is an upper limit on how long objects without an explicit
# expiry time will be considered fresh.

# VIOLATES the HTTP standard. Enabling this feature
# could make you liable for problems which it causes.
#
# override-lastmod enforces min age even on objects
# that were modified recently.
#
# reload-into-ims changes client no-cache or ``reload''
# to If-Modified-Since requests. Doing this VIOLATES the
# HTTP standard. Enabling this feature could make you
# liable for problems which it causes.
#
# ignore-reload ignores a client no-cache or ``reload''
# header. Doing this VIOLATES the HTTP standard. Enabling
# this feature could make you liable for problems which
# it causes.
#
# ignore-no-cache ignores any ``Pragma: no-cache'' and
# ``Cache-control: no-cache'' headers received from a server.
# The HTTP RFC never allows the use of this (Pragma) header
# from a server, only a client, though plenty of servers
# send it anyway.
#
# ignore-private ignores any ``Cache-control: private''
# headers received from a server. Doing this VIOLATES
# the HTTP standard. Enabling this feature could make you
# liable for problems which it causes.
#
# ignore-auth caches responses to requests with authorization,
# as if the originserver had sent ``Cache-control: public''
# in the response header. Doing this VIOLATES the HTTP standard.
# Enabling this feature could make you liable for problems which
# it causes.
#
# stale-while-revalidate=NN makes Squid perform an asyncronous
# cache validation if the object isn't more stale than NN.
# Doing this VIOLATES the HTTP standard. Enabling this
# feature could make you liable for problems which it
# causes.
#
# ignore-stale-while-revalidate makes Squid ignore any 'Cache-Control:
# stale-while-revalidate=NN' headers received from a server. Can be
# combined with stale-while-revalidate=NN to override the server provided
# value.
#
# max-stale=NN provided a maximum staleness factor. Squid won't
# serve objects more stale than this even if it failed to
# validate the object.
#
# negative-ttl=NN overrides the global negative_ttl parameter
# selectively for URLs matching this pattern (in seconds).
#
# Basically a cached object is:
#
# FRESH if expires < now, else STALE
# STALE if age > max
# FRESH if lm-factor < percent, else STALE
# FRESH if age < min
# else STALE

# TAG: quick_abort_pct (percent)
# The cache by default continues downloading aborted requests
# which are almost completed (less than 16 KB remaining). This
# may be undesirable on slow (e.g. SLIP) links and/or very busy
# caches. Impatient users may tie up file descriptors and
# bandwidth by repeatedly requesting and immediately aborting
# downloads.
#
# When the user aborts a request, Squid will check the

#
# If the transfer has less than 'quick_abort_min' KB remaining,
# it will finish the retrieval.
#
# If the transfer has more than 'quick_abort_max' KB remaining,

# TAG: range_offset_limit (bytes)
# Sets a upper limit on how far into the the file a Range request
# may be to cause Squid to prefetch the whole file. If beyond this
# limit Squid forwards the Range request as it is and the result
# is NOT cached.
#
# This is to stop a far ahead range request (lets say start at 17MB)
# from making Squid fetch the whole object up to that point before
# sending anything to the client.
#
# A value of -1 causes Squid to always fetch the object from the

# TAG: ie_refresh on|off
# Microsoft Internet Explorer up until version 5.5 Service
# Pack 1 has an issue with transparent proxies, wherein it

# a partial fix to the problem, by causing all IMS-REFRESH
# requests from older IE versions to check the origin server
# for fresh content. This reduces hit ratio by some amount
# (~10% in my experience), but allows users to actually get
# fresh content when they want it. Note because Squid
# cannot tell if the user is using 5.5 or 5.5SP1, the behavior
# of 5.5 is unchanged from old versions of Squid (i.e. a
# forced refresh is impossible). Newer versions of IE will,
# hopefully, continue to have the new behavior and will be
# handled based on that assumption. This option defaults to
# the old Squid behavior, which is better for hit ratios but
# worse for clients using IE, if they need to be able to
# force fresh content.

# 'http_anonymizer standard' option, you should use:
#
# header_access From deny all
# header_access Referer deny all
# header_access Server deny all
# header_access User-Agent deny all
# header_access WWW-Authenticate deny all
# header_access Link deny all
#
# Or, to reproduce the old 'http_anonymizer paranoid' feature
# you should use:
#
# header_access Allow allow all
# header_access Authorization allow all
# header_access WWW-Authenticate allow all
# header_access Proxy-Authorization allow all
# header_access Proxy-Authenticate allow all
# header_access Cache-Control allow all
# header_access Content-Encoding allow all
# header_access Content-Length allow all
# header_access Content-Type allow all
# header_access Date allow all
# header_access Expires allow all
# header_access Host allow all
# header_access If-Modified-Since allow all
# header_access Last-Modified allow all
# header_access Location allow all
# header_access Pragma allow all
# header_access Accept allow all
# header_access Accept-Charset allow all
# header_access Accept-Encoding allow all
# header_access Accept-Language allow all
# header_access Content-Language allow all
# header_access Mime-Version allow all
# header_access Retry-After allow all
# header_access Title allow all
# header_access Connection allow all
# header_access Proxy-Connection allow all
# header_access All deny all
#
# By default, all headers are allowed (no anonymizing is
# performed).
#
#Default:
# none
# TAG: header_replace
# Usage: header_replace header_name message
# Example: header_replace User-Agent Nutscrape/1.0 (CP/M; 8-bit)
#
# This option allows you to change the contents of headers
# denied with header_access above, by replacing them with
# some fixed string. This replaces the old fake_user_agent
# option.
#
# By default, headers are removed if denied.
#
#Default:
# none
# TAG: relaxed_header_parser on|off|warn
# In the default "on" setting Squid accepts certain forms
# of non-compliant HTTP messages where it is unambiguous
# what the sending application intended even if the message
# is not correctly formatted. The messages is then normalized
# to the correct form when forwarded by Squid.
#
# If set to "warn" then a warning will be emitted in cache.log
# each time such HTTP error is encountered.
#
# If set to "off" then such HTTP errors will cause the request
# or response to be rejected.
#
#Default:
# relaxed_header_parser on
# TAG: server_http11 on|off
# This option enables the use ot HTTP/1.1 on outgoing "direct" requests.
# See also the http11 cache_peer option.
# Note: The HTTP/1.1 support is still incomplete, with an
# internal HTTP/1.0 hop. As result 1xx responses will not
# be forwarded.
#
#Default:
# server_http11 off
# TAG: ignore_expect_100 on|off
# This option makes Squid ignore any Expect: 100-continue header present
# in the request.
# Note: Enabling this is a HTTP protocol violation, but some client may
# not handle it well..
#
#Default:
# ignore_expect_100 off
# TAG: external_refresh_check
# This option defines an external helper for determining whether to
# refresh a stale response. It will be called when Squid receives a
# request for a cached response that is stale; the helper can either
# confirm that the response is stale with a STALE response, or
# extend the freshness of the response (thereby avoiding a refresh
# check) with a FRESH response, along with a freshness=nnn keyword.
#
# external_refresh_check [options] FORMAT.. /path/to/helper [helper_args]
#
# If present, helper_args will be passed to the helper on the command
# line verbatim.
#
# Options:
#
# children=n Number of processes to spawn to service external
# refresh checks (default 5).
# concurrency=n Concurrency level per process. Only used with
# helpers capable of processing more than one query
# at a time.
#
# When using the concurrency option, the protocol is changed by introducing
# a query channel tag infront of the request/response. The query channel
# tag is a number between 0 and concurrencyâ1.
#
# FORMAT specifications:
#
# %CACHE_URI The URI of the cached response
# %RES{Header} HTTP response header value
# %AGE The age of the cached response
#
# The request sent to the helper consists of the data in the format
# specification in the order specified.
#
# The helper receives lines per the above format specification, and
# returns lines starting with OK or ERR indicating the validity of
# the request and optionally followed by additional keywords with
# more details. URL escaping is used to protect each value in both
# requests and responses.
#
# General result syntax:
#
# FRESH / STALE keyword=value ...
#
# Defined keywords:
#
# freshness=nnn The number of seconds to extend the freshness of
# the response by.
# log=string String to be logged in access.log. Available as
# %ef in logformat specifications.
# res{Header}=value
# Value to update response headers with. If already
# present, the supplied value completely replaces
# the cached value.
#
# In the event of a helperârelated error (e.g., overload), Squid
# will always default to STALE.
#
#Default:
# none
# TIMEOUTS
# -----------------------------------------------------------------------------
# TAG: forward_timeout time-units
# This parameter specifies how long Squid should at most attempt in
# finding a forwarding path for the request before giving up.
#
#Default:
# forward_timeout 4 minutes
# TAG: connect_timeout time-units
# This parameter specifies how long to wait for the TCP connect to
# the requested server or peer to complete before Squid should
# attempt to find another path where to forward the request.
#
#Default:
# connect_timeout 1 minute
# TAG: peer_connect_timeout time-units
# This parameter specifies how long to wait for a pending TCP
# connection to a peer cache. The default is 30 seconds. You
# may also set different timeout values for individual neighbors
# with the 'connect-timeout' option on a 'cache_peer' line.
#
#Default:
# peer_connect_timeout 30 seconds
# TAG: read_timeout time-units
# The read_timeout is applied on server-side connections. After
# each successful read(), the timeout will be extended by this
# amount. If no data is read again after this amount of time,
# the request is aborted and logged with ERR_READ_TIMEOUT. The
# default is 15 minutes.
#
#Default:
# read_timeout 15 minutes
# TAG: request_timeout
# How long to wait for an HTTP request after initial
# connection establishment.
#
#Default:
# request_timeout 5 minutes
# TAG: persistent_request_timeout
# How long to wait for the next HTTP request on a persistent
# connection after the previous request completes.
#
#Default:
# persistent_request_timeout 2 minutes
# TAG: client_lifetime time-units
# The maximum amount of time a client (browser) is allowed to
# remain connected to the cache process. This protects the Cache
# from having a lot of sockets (and hence file descriptors) tied up
# in a CLOSE_WAIT state from remote clients that go away without
# properly shutting down (either because of a network failure or
# because of a poor client implementation). The default is one
# day, 1440 minutes.
#
# NOTE: The default value is intended to be much larger than any
# client would ever need to be connected to your cache. You
# should probably change client_lifetime only as a last resort.
# If you seem to have many client connections tying up
# filedescriptors, we recommend first tuning the read_timeout,
# request_timeout, persistent_request_timeout and quick_abort values.
#
#Default:
# client_lifetime 1 day
# TAG: half_closed_clients
# Some clients may shutdown the sending side of their TCP
# connections, while leaving their receiving sides open. Sometimes,
# Squid can not tell the difference between a half-closed and a
# fully-closed TCP connection. By default, half-closed client
# connections are kept open until a read(2) or write(2) on the
# socket returns an error. Change this option to 'off' and Squid
# will immediately close client connections when read(2) returns
# "no more data to read."
#
#Default:
# half_closed_clients on
# TAG: pconn_timeout
# Timeout for idle persistent connections to servers and other
# proxies.
#
#Default:
# pconn_timeout 1 minute
# TAG: ident_timeout
# Maximum time to wait for IDENT lookups to complete.
#
# If this is too high, and you enabled IDENT lookups from untrusted
# users, you might be susceptible to denial-of-service by having
# many ident requests going at once.
#
#Default:
# ident_timeout 10 seconds
# TAG: shutdown_lifetime time-units
# When SIGTERM or SIGHUP is received, the cache is put into
# "shutdown pending" mode until all active sockets are closed.
# This value is the lifetime to set for all open descriptors
# during shutdown mode. Any active clients after this many
# seconds will receive a 'timeout' message.
#
#Default:
# shutdown_lifetime 30 seconds
# ADMINISTRATIVE PARAMETERS
# -----------------------------------------------------------------------------
# TAG: cache_mgr
# Email-address of local cache manager who will receive
# mail if the cache dies. The default is "webmaster".
#
#Default:
# cache_mgr webmaster
# TAG: mail_from
# From: email-address for mail sent when the cache dies.
# The default is to use 'appname@unique_hostname'.
# Default appname value is "squid", can be changed into
# src/globals.h before building squid.
#
#Default:
# none
# TAG: mail_program
# Email program used to send mail if the cache dies.
# The default is "mail". The specified program must comply
# with the standard Unix mail syntax:
# mail-program recipient < mailfile
#
# Optional command line options can be specified.
#
#Default:
# mail_program mail
# TAG: cache_effective_user
# If you start Squid as root, it will change its effective/real
# UID/GID to the user specified below. The default is to change
# to UID to proxy. If you define cache_effective_user, but not
# cache_effective_group, Squid sets the GID to the effective
# user's default group ID (taken from the password file) and
# supplementary group list from the from groups membership of
# cache_effective_user.
#
#Default:
# cache_effective_user proxy ## no hace falta modificar fefu 20090824
# TAG: cache_effective_group
# If you want Squid to run with a specific GID regardless of
# the group memberships of the effective user then set this
# to the group (or GID) you want Squid to run as. When set
# all other group privileges of the effective user is ignored
# and only this GID is effective. If Squid is not started as
# root the user starting Squid must be member of the specified
# group.
#
#Default:
# none
# TAG: httpd_suppress_version_string on|off
# Suppress Squid version string info in HTTP headers and HTML error pages.
#
#Default:
# httpd_suppress_version_string off
# TAG: visible_hostname
# If you want to present a special hostname in error messages, etc,
# define this. Otherwise, the return value of gethostname()
# will be used. If you have multiple caches in a cluster and
# get errors about IP-forwarding you must set them to have individual
# names with this setting.
#
#Default:
# none
# TAG: unique_hostname
# If you want to have multiple machines with the same
# 'visible_hostname' you must give each machine a different
# 'unique_hostname' so forwarding loops can be detected.
#
#Default:
# none
# TAG: hostname_aliases
# A list of other DNS names your cache has.
#
#Default:
# none
# TAG: umask
# Minimum umask which should be enforced while the proxy
# is running, in addition to the umask set at startup.
#
# Note: Should start with a 0 to indicate the normal octal
# representation of umasks
#
#Default:
# umask 027
# OPTIONS FOR THE CACHE REGISTRATION SERVICE
# -----------------------------------------------------------------------------
#
# This section contains parameters for the (optional) cache
# announcement service. This service is provided to help
# cache administrators locate one another in order to join or
# create cache hierarchies.
#
# An 'announcement' message is sent (via UDP) to the registration
# service by Squid. By default, the announcement message is NOT
# SENT unless you enable it with 'announce_period' below.
#
# The announcement message includes your hostname, plus the
# following information from this configuration file:
#
# http_port
# icp_port
# cache_mgr
#
# All current information is processed regularly and made
# available on the Web at http://www.ircache.net/Cache/Tracker/.
# TAG: announce_period
# This is how frequently to send cache announcements. The
# default is `0' which disables sending the announcement
# messages.
#
# To enable announcing your cache, just uncomment the line
# below.
#
#Default:
# announce_period 0
#
#To enable announcing your cache, just uncomment the line below.
#announce_period 1 day
# TAG: announce_host
# TAG: announce_file
# TAG: announce_port
# announce_host and announce_port set the hostname and port
# number where the registration message will be sent.
#
# Hostname will default to 'tracker.ircache.net' and port will
# default default to 3131. If the 'filename' argument is given,
# the contents of that file will be included in the announce
# message.
#
#Default:
# announce_host tracker.ircache.net
# announce_port 3131
# HTTPD-ACCELERATOR OPTIONS
# -----------------------------------------------------------------------------
# TAG: httpd_accel_no_pmtu_disc on|off
# In many setups of transparently intercepting proxies Path-MTU
# discovery can not work on traffic towards the clients. This is
# the case when the intercepting device does not fully track
# connections and fails to forward ICMP must fragment messages
# to the cache server.
#
# If you have such setup and experience that certain clients
# sporadically hang or never complete requests set this to on.
#
#Default:
# httpd_accel_no_pmtu_disc off
# DELAY POOL PARAMETERS
# -----------------------------------------------------------------------------
# TAG: delay_pools
# This represents the number of delay pools to be used. For example,
# if you have one class 2 delay pool and one class 3 delays pool, you
# have a total of 2 delay pools.
#
#Default:
# delay_pools 0
# TAG: delay_class
# This defines the class of each delay pool. There must be exactly one
# delay_class line for each delay pool. For example, to define two
# delay pools, one of class 2 and one of class 3, the settings above
# and here would be:
#
#Example:
# delay_pools 2 # 2 delay pools
# delay_class 1 2 # pool 1 is a class 2 pool
# delay_class 2 3 # pool 2 is a class 3 pool
#
# The delay pool classes are:
#
# class 1 Everything is limited by a single aggregate
# bucket.
#
# class 2 Everything is limited by a single aggregate
# bucket as well as an "individual" bucket chosen
# from bits 25 through 32 of the IP address.
#
# class 3 Everything is limited by a single aggregate
# bucket as well as a "network" bucket chosen
# from bits 17 through 24 of the IP address and a
# "individual" bucket chosen from bits 17 through
# 32 of the IP address.
#
# NOTE: If an IP address is a.b.c.d
# -> bits 25 through 32 are "d"
# -> bits 17 through 24 are "c"
# -> bits 17 through 32 are "c * 256 + d"
#
#Default:
# none
# TAG: delay_access
# This is used to determine which delay pool a request falls into.
#
# delay_access is sorted per pool and the matching starts with pool 1,
# then pool 2, ..., and finally pool N. The first delay pool where the
# request is allowed is selected for the request. If it does not allow
# the request to any pool then the request is not delayed (default).
#
# For example, if you want some_big_clients in delay
# pool 1 and lotsa_little_clients in delay pool 2:
#
#Example:
# delay_access 1 allow some_big_clients
# delay_access 1 deny all
# delay_access 2 allow lotsa_little_clients
# delay_access 2 deny all
#
#Default:
# none
# TAG: delay_parameters
# This defines the parameters for a delay pool. Each delay pool has
# a number of "buckets" associated with it, as explained in the
# description of delay_class. For a class 1 delay pool, the syntax is:
#
#delay_parameters pool aggregate
#
# For a class 2 delay pool:
#
#delay_parameters pool aggregate individual
#
# For a class 3 delay pool:
#
#delay_parameters pool aggregate network individual
#
# The variables here are:
#
# pool a pool number - ie, a number between 1 and the
# number specified in delay_pools as used in
# delay_class lines.
#
# aggregate the "delay parameters" for the aggregate bucket
# (class 1, 2, 3).
#
# individual the "delay parameters" for the individual
# buckets (class 2, 3).
#
# network the "delay parameters" for the network buckets
# (class 3).
#
# A pair of delay parameters is written restore/maximum, where restore is
# the number of bytes (not bits - modem and network speeds are usually
# quoted in bits) per second placed into the bucket, and maximum is the
# maximum number of bytes which can be in the bucket at any time.
#
# For example, if delay pool number 1 is a class 2 delay pool as in the
# above example, and is being used to strictly limit each host to 64kbps
# (plus overheads), with no overall limit, the line is:
#
#delay_parameters 1 -1/-1 8000/8000
#
# Note that the figure -1 is used to represent "unlimited".
#
# And, if delay pool number 2 is a class 3 delay pool as in the above
# example, and you want to limit it to a total of 256kbps (strict limit)
# with each 8-bit network permitted 64kbps (strict limit) and each
# individual host permitted 4800bps with a bucket maximum size of 64kb
# to permit a decent web page to be downloaded at a decent speed
# (if the network is not being limited due to overuse) but slow down
# large downloads more significantly:
#
#delay_parameters 2 32000/32000 8000/8000 600/8000
#
# There must be one delay_parameters line for each delay pool.
#
#Default:
# none
# TAG: delay_initial_bucket_level (percent, 0-100)
# The initial bucket percentage is used to determine how much is put
# in each bucket when squid starts, is reconfigured, or first notices
# a host accessing it (in class 2 and class 3, individual hosts and
# networks only have buckets associated with them once they have been
# "seen" by squid).
#
#Default:
# delay_initial_bucket_level 50
# WCCPv1 AND WCCPv2 CONFIGURATION OPTIONS
# -----------------------------------------------------------------------------
# TAG: wccp_router
# TAG: wccp2_router
# Use this option to define your WCCP ``home'' router for
# Squid.
#
# wccp_router supports a single WCCP(v1) router
#
# wccp2_router supports multiple WCCPv2 routers
#
# only one of the two may be used at the same time and defines
# which version of WCCP to use.
#
#Default:
# wccp_router 0.0.0.0
# TAG: wccp_version
# This directive is only relevant if you need to set up WCCP(v1)
# to some very old and end-of-life Cisco routers. In all other
# setups it must be left unset or at the default setting.
# It defines an internal version in the WCCP(v1) protocol,
# with version 4 being the officially documented protocol.
#
# According to some users, Cisco IOS 11.2 and earlier only
# support WCCP version 3. If you're using that or an earlier
# version of IOS, you may need to change this value to 3, otherwise
# do not specify this parameter.
#
#Default:
# wccp_version 4
# TAG: wccp2_rebuild_wait
# If this is enabled Squid will wait for the cache dir rebuild to finish
# before sending the first wccp2 HereIAm packet
#
#Default:
# wccp2_rebuild_wait on
# TAG: wccp2_forwarding_method
# WCCP2 allows the setting of forwarding methods between the
# router/switch and the cache. Valid values are as follows:
#
# 1 - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
# 2 - L2 redirect (forward the packet using Layer 2/MAC rewriting)
#
# Currently (as of IOS 12.4) cisco routers only support GRE.
# Cisco switches only support the L2 redirect assignment method.
#
#Default:
# wccp2_forwarding_method 1
# TAG: wccp2_return_method
# WCCP2 allows the setting of return methods between the
# router/switch and the cache for packets that the cache
# decides not to handle. Valid values are as follows:
#
# 1 - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
# 2 - L2 redirect (forward the packet using Layer 2/MAC rewriting)
#
# Currently (as of IOS 12.4) cisco routers only support GRE.
# Cisco switches only support the L2 redirect assignment.
#
# If the "ip wccp redirect exclude in" command has been
# enabled on the cache interface, then it is still safe for
# the proxy server to use a l2 redirect method even if this
# option is set to GRE.
#
#Default:
# wccp2_return_method 1
# TAG: wccp2_assignment_method
# WCCP2 allows the setting of methods to assign the WCCP hash
# Valid values are as follows:
#
# 1 - Hash assignment
# 2 - Mask assignment
#
# As a general rule, cisco routers support the hash assignment method
# and cisco switches support the mask assignment method.
#
#Default:
# wccp2_assignment_method 1
# TAG: wccp2_service
# WCCP2 allows for multiple traffic services. There are two
# types: "standard" and "dynamic". The standard type defines
# one service id - http (id 0). The dynamic service ids can be from
# 51 to 255 inclusive. In order to use a dynamic service id
# one must define the type of traffic to be redirected; this is done
# using the wccp2_service_info option.
#
# The "standard" type does not require a wccp2_service_info option,
# just specifying the service id will suffice.
#
# MD5 service authentication can be enabled by adding
# "password=<password>" to the end of this service declaration.
#
# Examples:
#
# wccp2_service standard 0 # for the 'web-cache' standard service
# wccp2_service dynamic 80 # a dynamic service type which will be
# # fleshed out with subsequent options.
# wccp2_service standard 0 password=foo
#
#
#Default:
# wccp2_service standard 0
# TAG: wccp2_service_info
# Dynamic WCCPv2 services require further information to define the
# traffic you wish to have diverted.
#
# The format is:
#
# wccp2_service_info <id> protocol=<protocol> flags=<flag>,<flag>..
# priority=<priority> ports=<port>,<port>..
#
# The relevant WCCPv2 flags:
# + src_ip_hash, dst_ip_hash
# + source_port_hash, dst_port_hash
# + src_ip_alt_hash, dst_ip_alt_hash
# + src_port_alt_hash, dst_port_alt_hash
# + ports_source
#
# The port list can be one to eight entries.
#
# Example:
#
# wccp2_service_info 80 protocol=tcp flags=src_ip_hash,ports_source
# priority=240 ports=80
#
# Note: the service id must have been defined by a previous
# 'wccp2_service dynamic <id>' entry.
#
#Default:
# none
# TAG: wccp2_weight
# Each cache server gets assigned a set of the destination
# hash proportional to their weight.
#
#Default:
# wccp2_weight 10000
# TAG: wccp_address
# TAG: wccp2_address
# Use this option if you require WCCP to use a specific
# interface address.
#
# The default behavior is to not bind to any specific address.
#
#Default:
# wccp_address 0.0.0.0
# wccp2_address 0.0.0.0
# PERSISTENT CONNECTION HANDLING
# -----------------------------------------------------------------------------
#
# Also see "pconn_timeout" in the TIMEOUTS section
# TAG: client_persistent_connections
# TAG: server_persistent_connections
# Persistent connection support for clients and servers. By
# default, Squid uses persistent connections (when allowed)
# with its clients and servers. You can use these options to
# disable persistent connections with clients and/or servers.
#
#Default:
# client_persistent_connections on
# server_persistent_connections on
# TAG: persistent_connection_after_error
# With this directive the use of persistent connections after
# HTTP errors can be disabled. Useful if you have clients
# who fail to handle errors on persistent connections proper.
#
#Default:
# persistent_connection_after_error off
# TAG: detect_broken_pconn
# Some servers have been found to incorrectly signal the use
# of HTTP/1.0 persistent connections even on replies not
# compatible, causing significant delays. This server problem
# has mostly been seen on redirects.
#
# By enabling this directive Squid attempts to detect such
# broken replies and automatically assume the reply is finished
# after 10 seconds timeout.
#
#Default:
# detect_broken_pconn off
# CACHE DIGEST OPTIONS
# -----------------------------------------------------------------------------
# TAG: digest_generation
# This controls whether the server will generate a Cache Digest
# of its contents.
#
#Default:
# digest_generation on
# TAG: digest_bits_per_entry
# This is the number of bits of the server's Cache Digest which
# will be associated with the Digest entry for a given HTTP
# Method and URL (public key) combination. The default is 5.
#
#Default:
# digest_bits_per_entry 5
# TAG: digest_rebuild_period (seconds)
# This is the wait time between Cache Digest rebuilds.
#
#Default:
# digest_rebuild_period 1 hour
# TAG: digest_rewrite_period (seconds)
# This is the wait time between Cache Digest writes to disk.
#
#Default:
# digest_rewrite_period 1 hour
# TAG: digest_swapout_chunk_size (bytes)
# This is the number of bytes of the Cache Digest to write to
# disk at a time. It defaults to 4096 bytes (4KB), the Squid
# default swap page.
#
#Default:
# digest_swapout_chunk_size 4096 bytes
# TAG: digest_rebuild_chunk_percentage (percent, 0-100)
# This is the percentage of the Cache Digest to be scanned at a
# time. By default it is set to 10% of the Cache Digest.
#
#Default:
# digest_rebuild_chunk_percentage 10
# SNMP OPTIONS
# -----------------------------------------------------------------------------
# TAG: snmp_port
# Squid can now serve statistics and status information via SNMP.
# By default it listens to port 3401 on the machine. If you don't
# wish to use SNMP, set this to "0".
#
# Note: on Debian/Linux, the default is zero - you need to
# set it to 3401 to enable it.
#
#Default:
# snmp_port 0
# TAG: snmp_access
# Allowing or denying access to the SNMP port.
#
# All access to the agent is denied by default.
# usage:
#
# snmp_access allow|deny [!]aclname ...
#
#Example:
# snmp_access allow snmppublic localhost
# snmp_access deny all
#
#Default:
# snmp_access deny all
# TAG: snmp_incoming_address
# TAG: snmp_outgoing_address
# Just like 'udp_incoming_address' above, but for the SNMP port.
#
# snmp_incoming_address is used for the SNMP socket receiving
# messages from SNMP agents.
# snmp_outgoing_address is used for SNMP packets returned to SNMP
# agents.
#
# The default snmp_incoming_address (0.0.0.0) is to listen on all
# available network interfaces.
#
# If snmp_outgoing_address is set to 255.255.255.255 (the default)
# it will use the same socket as snmp_incoming_address. Only
# change this if you want to have SNMP replies sent using another
# address than where this Squid listens for SNMP queries.

# ICP OPTIONS
# -----------------------------------------------------------------------------
# TAG: icp_port
# The port number where Squid sends and receives ICP queries to

#
#Default:
# icp_port 3130
# TAG: htcp_port
# The port number where Squid sends and receives HTCP queries to
# and from neighbor caches. To turn it on you want to set it 4827.
# By default it is set to "0" (disabled).
#
#Default:
# htcp_port 0
# TAG: log_icp_queries on|off
# If set, ICP queries are logged to access.log. You may wish
# do disable this if your ICP load is VERY high to speed things
# up or to simplify log analysis.
#
#Default:
# log_icp_queries on
# TAG: udp_incoming_address
# udp_incoming_address is used for UDP packets received from other
# caches.
#
# The default behavior is to not bind to any specific address.
#
# Only change this if you want to have all UDP queries received on
# a specific interface/address.
#
# NOTE: udp_incoming_address is used by the ICP, HTCP, and DNS

#
# The default behavior is to not bind to any specific address.
#
# Instead it will use the same socket as udp_incoming_address.
# Only change this if you want to have UDP queries sent using another

# TAG: icp_hit_stale on|off
# If you want to return ICP_HIT for stale cache objects, set this
# option to 'on'. If you have sibling relationships with caches
# in other administrative domains, this should be 'off'. If you only
# have sibling relationships with caches under your control,
# it is probably okay to set this to 'on'.
# If set to 'on', your siblings should use the option "allow-miss"
# on their cache_peer lines for connecting to you.
#
#Default:

# If using the ICMP pinging stuff, do direct fetches for sites
# which are no more than this many rtt milliseconds away.
#
#Default:
# minimum_direct_rtt 400
# TAG: netdb_low
# TAG: netdb_high
# The low and high water marks for the ICMP measurement
# database. These are counts, not percents. The defaults are
# 900 and 1000. When the high water mark is reached, database
# entries will be deleted until the low mark is reached.
#
#Default:
# netdb_low 900
# netdb_high 1000
# TAG: netdb_ping_period
# The minimum period for measuring a site. There will be at
# least this much delay between successive pings to the same
# network. The default is five minutes.
#
#Default:
# netdb_ping_period 5 minutes
# TAG: query_icmp on|off
# If you want to ask your peers to include ICMP data in their ICP
# replies, enable this option.
#
# If your peer has configured Squid (during compilation) with
# '--enable-icmp' that peer will send ICMP pings to origin server
# sites of the URLs it receives. If you enable this option the
# ICP replies from that peer will include the ICMP data (if available).
# Then, when choosing a parent cache, Squid will choose the parent with
# the minimal RTT to the origin server. When this happens, the
# hierarchy field of the access.log will be
# "CLOSEST_PARENT_MISS". This option is off by default.
#
#Default:
# query_icmp off
# TAG: test_reachability on|off
# When this is 'on', ICP MISS replies will be ICP_MISS_NOFETCH
# instead of ICP_MISS if the target host is NOT in the ICMP
# database, or has a zero RTT.
#
#Default:
# test_reachability off
# TAG: icp_query_timeout (msec)
# Normally Squid will automatically determine an optimal ICP
# query timeout value based on the round-trip-time of recent ICP
# queries. If you want to override the value determined by
# Squid, set this 'icp_query_timeout' to a non-zero value. This
# value is specified in MILLISECONDS, so, to use a 2-second
# timeout (the old default), you would write:
#
# icp_query_timeout 2000
#
#Default:
# icp_query_timeout 0
# TAG: maximum_icp_query_timeout (msec)
# Normally the ICP query timeout is determined dynamically. But
# sometimes it can lead to very large values (say 5 seconds).
# Use this option to put an upper limit on the dynamic timeout
# value. Do NOT use this option to always use a fixed (instead
# of a dynamic) timeout value. To set a fixed timeout see the
# 'icp_query_timeout' directive.
#
#Default:
# maximum_icp_query_timeout 2000
# TAG: minimum_icp_query_timeout (msec)
# Normally the ICP query timeout is determined dynamically. But
# sometimes it can lead to very small timeouts, even lower than
# the normal latency variance on your link due to traffic.
# Use this option to put an lower limit on the dynamic timeout
# value. Do NOT use this option to always use a fixed (instead
# of a dynamic) timeout value. To set a fixed timeout see the

# MULTICAST ICP OPTIONS
# -----------------------------------------------------------------------------
# TAG: mcast_groups
# This tag specifies a list of multicast groups which your server
# should join to receive multicasted ICP queries.
#
# NOTE! Be very careful what you put here! Be sure you
# understand the difference between an ICP _query_ and an ICP
# _reply_. This option is to be set only if you want to RECEIVE
# multicast queries. Do NOT set this option to SEND multicast
# ICP (use cache_peer for that). ICP replies are always sent via
# unicast, so this option does not affect whether or not you will
# receive replies from multicast group members.
#
# You must be very careful to NOT use a multicast address which
# is already in use by another group of caches.
#
# If you are unsure about multicast, please read the Multicast
# chapter in the Squid FAQ (http://www.squid-cache.org/FAQ/).
#
# Usage: mcast_groups 239.128.16.128 224.0.1.20
#
# By default, Squid doesn't listen on any multicast groups.
#
#Default:
# none
# TAG: mcast_miss_addr
# Note: This option is only available if Squid is rebuilt with the
# --enable-multicast-miss option
#
# If you enable this option, every "cache miss" URL will
# be sent out on the specified multicast address.
#
# Do not enable this option unless you are are absolutely
# certain you understand what you are doing.
#
#Default:
# mcast_miss_addr 255.255.255.255
# TAG: mcast_miss_ttl
# Note: This option is only available if Squid is rebuilt with the
# --enable-multicast-miss option
#
# This is the time-to-live value for packets multicasted
# when multicasting off cache miss URLs is enabled. By
# default this is set to 'site scope', i.e. 16.
#
#Default:
# mcast_miss_ttl 16
# TAG: mcast_miss_port
# Note: This option is only available if Squid is rebuilt with the
# --enable-multicast-miss option
#
# This is the port number to be used in conjunction with
# 'mcast_miss_addr'.
#
#Default:
# mcast_miss_port 3135
# TAG: mcast_miss_encode_key
# Note: This option is only available if Squid is rebuilt with the
# --enable-multicast-miss option
#
# The URLs that are sent in the multicast miss stream are
# encrypted. This is the encryption key.
#
#Default:
# mcast_miss_encode_key XXXXXXXXXXXXXXXX
# TAG: mcast_icp_query_timeout (msec)
# For multicast peers, Squid regularly sends out ICP "probes" to
# count how many other peers are listening on the given multicast
# address. This value specifies how long Squid should wait to
# count all the replies. The default is 2000 msec, or 2
# seconds.
#
#Default:
# mcast_icp_query_timeout 2000
# INTERNAL ICON OPTIONS
# -----------------------------------------------------------------------------
# TAG: icon_directory
# Where the icons are stored. These are normally kept in
# /usr/share/squid/icons
#
#Default:
# icon_directory /usr/share/squid/icons
# TAG: global_internal_static
# This directive controls is Squid should intercept all requests for
# /squid-internal-static/ no matter which host the URL is requesting
# (default on setting), or if nothing special should be done for
# such URLs (off setting). The purpose of this directive is to make
# icons etc work better in complex cache hierarchies where it may
# not always be possible for all corners in the cache mesh to reach
# the server generating a directory listing.
#
#Default:
# global_internal_static on
# TAG: short_icon_urls
# If this is enabled Squid will use short URLs for icons.
#
# If off the URLs for icons will always be absolute URLs
# including the proxy name and port.
#
#Default:
# short_icon_urls off
# ERROR PAGE OPTIONS
# -----------------------------------------------------------------------------
# TAG: error_directory
# If you wish to create your own versions of the default
# (English) error files, either to customize them to suit your
# language or company copy the template English files to another
# directory and point this tag at them.
#
# The squid developers are interested in making squid available in
# a wide variety of languages. If you are making translations for a
# langauge that Squid does not currently provide please consider
# contributing your translation back to the project.
#
#Default:
# error_directory /usr/share/squid/errors/English
# TAG: error_map
# Map errors to custom messages
#
# error_map message_url http_status ...
#
# http_status ... is a list of HTTP status codes or Squid error
# messages.
#
# Use in accelerators to substitute the error messages returned
# by servers with other custom errors.
#
# error_map http://your.server/error/404.shtml 404
#
# Requests for error messages is a GET request for the configured
# URL with the following special headers
#
# X-Error-Status: The received HTTP status code (i.e. 404)
# X-Request-URI: The requested URI where the error occurred
#
# In Addition the following headers are forwarded from the client
# request:
#
# User-Agent, Cookie, X-Forwarded-For, Via, Authorization,
# Accept, Referer
#
# And the following headers from the server reply:
#
# Server, Via, Location, Content-Location
#
# The reply returned to the client will carry the original HTTP
# headers from the real error message, but with the reply body
# of the configured error message.
#
#
#Default:
# none
# TAG: err_html_text
# HTML text to include in error messages. Make this a "mailto"
# URL to your admin address, or maybe just a link to your
# organizations Web page.
#
# To include this in your error messages, you must rewrite
# the error template files (found in the "errors" directory).
# Wherever you want the 'err_html_text' line to appear,
# insert a %L tag in the error template file.
#
#Default:
# none
# TAG: deny_info
# Usage: deny_info err_page_name acl
# or deny_info http://... acl
# Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
#
# This can be used to return a ERR_ page for requests which
# do not pass the 'http_access' rules. Squid remembers the last
# acl it evaluated in http_access, and if a 'deny_info' line exists
# for that ACL Squid returns a corresponding error page.
#
# The acl is typically the last acl on the http_access deny line which
# denied access. The exceptions to this rule are:
# - When Squid needs to request authentication credentials. It's then
# the first authentication related acl encountered
# - When none of the http_access lines matches. It's then the last
# acl processed on the last http_access line.
#
# You may use ERR_ pages that come with Squid or create your own pages
# and put them into the configured errors/ directory.
#
# Alternatively you can specify an error URL. The browsers will
# get redirected (302) to the specified URL. %s in the redirection
# URL will be replaced by the requested URL.
#
# Alternatively you can tell Squid to reset the TCP connection
# by specifying TCP_RESET.
#
#Default:
# none
# OPTIONS INFLUENCING REQUEST FORWARDING
# -----------------------------------------------------------------------------
# TAG: nonhierarchical_direct
# By default, Squid will send any non-hierarchical requests
# (matching hierarchy_stoplist or not cacheable request type) direct
# to origin servers.
#
# If you set this to off, Squid will prefer to send these
# requests to parents.
#
# Note that in most configurations, by turning this off you will only
# add latency to these request without any improvement in global hit
# ratio.
#
# If you are inside an firewall see never_direct instead of
# this directive.
#
#Default:
# nonhierarchical_direct on
# TAG: prefer_direct
# Normally Squid tries to use parents for most requests. If you for some
# reason like it to first try going direct and only use a parent if
# going direct fails set this to on.
#
# By combining nonhierarchical_direct off and prefer_direct on you
# can set up Squid to use a parent as a backup path if going direct
# fails.
#
# Note: If you want Squid to use parents for all requests see
# the never_direct directive. prefer_direct only modifies how Squid
# acts on cacheable requests.
#
#Default:
# prefer_direct off
# TAG: ignore_ims_on_miss on|off
# This options makes Squid ignore If-Modified-Since on
# cache misses. This is useful while the cache is
# mostly empty to more quickly have the cache populated.
#
#Default:
# ignore_ims_on_miss off
# TAG: always_direct
# Usage: always_direct allow|deny [!]aclname ...
#
# Here you can use ACL elements to specify requests which should
# ALWAYS be forwarded by Squid to the origin servers without using
# any peers. For example, to always directly forward requests for
# local servers ignoring any parents or siblings you may have use
# something like:
#
# acl local-servers dstdomain my.domain.net
# always_direct allow local-servers
#
# To always forward FTP requests directly, use
#
# acl FTP proto FTP
# always_direct allow FTP
#
# NOTE: There is a similar, but opposite option named
# 'never_direct'. You need to be aware that "always_direct deny
# foo" is NOT the same thing as "never_direct allow foo". You
# may need to use a deny rule to exclude a more-specific case of
# some other rule. Example:
#
# acl local-external dstdomain external.foo.net
# acl local-servers dstdomain .foo.net
# always_direct deny local-external
# always_direct allow local-servers
#
# NOTE: If your goal is to make the client forward the request
# directly to the origin server bypassing Squid then this needs
# to be done in the client configuration. Squid configuration
# can only tell Squid how Squid should fetch the object.
#
# NOTE: This directive is not related to caching. The replies
# is cached as usual even if you use always_direct. To not cache
# the replies see no_cache.
#
# This option replaces some v1.1 options such as local_domain
# and local_ip.
#
#Default:
# none
# TAG: never_direct
# Usage: never_direct allow|deny [!]aclname ...
#
# never_direct is the opposite of always_direct. Please read
# the description for always_direct if you have not already.
#
# With 'never_direct' you can use ACL elements to specify
# requests which should NEVER be forwarded directly to origin
# servers. For example, to force the use of a proxy for all
# requests, except those in your local domain use something like:
#
# acl local-servers dstdomain .foo.net
# acl all src 0.0.0.0/0.0.0.0
# never_direct deny local-servers
# never_direct allow all
#
# or if Squid is inside a firewall and there are local intranet
# servers inside the firewall use something like:
#
# acl local-intranet dstdomain .foo.net
# acl local-external dstdomain external.foo.net
# always_direct deny local-external
# always_direct allow local-intranet
# never_direct allow all
#
# This option replaces some v1.1 options such as inside_firewall
# and firewall_ip.
#
#Default:
# none
# ADVANCED NETWORKING OPTIONS
# -----------------------------------------------------------------------------
# TAG: max_filedescriptors
# The maximum number of filedescriptors supported.
#
# The default "0" means Squid inherits the current ulimit setting.
#
# Note: Changing this requires a restart of Squid. Also
# not all comm loops supports values larger than --with-maxfd.
#
#Default:
# max_filedescriptors 0
# TAG: accept_filter
# FreeBSD:
#
# The name of an accept(2) filter to install on Squid's
# listen socket(s). This feature is perhaps specific to
# FreeBSD and requires support in the kernel.
#
# The 'httpready' filter delays delivering new connections
# to Squid until a full HTTP request has been received.
# See the accf_http(9) man page for details.
#
# The 'dataready' filter delays delivering new connections
# to Squid until there is some data to process.
# See the accf_dataready(9) man page for details.
#
# Linux:
#
# The 'data' filter delays delivering of new connections
# to Squid until there is some data to process by TCP_ACCEPT_DEFER.
# You may optionally specify a number of seconds to wait by
# 'data=N' where N is the number of seconds. Defaults to 30
# if not specified. See the tcp(7) man page for details.
#EXAMPLE:
## FreeBSD
#accept_filter httpready
## Linux
#accept_filter data
#
#Default:
# none
# TAG: tcp_recv_bufsize (bytes)
# Size of receive buffer to set for TCP sockets. Probably just
# as easy to change your kernel's default. Set to zero to use
# the default buffer size.
#
#Default:
# tcp_recv_bufsize 0 bytes
# TAG: incoming_rate
# This directive controls how aggressive Squid should accept new
# connections compared to processing existing connections.
# The lower number the more frequent Squid will look for new
# incoming requests.
#
#Default:
# incoming_rate 30
# DNS OPTIONS
# -----------------------------------------------------------------------------
# TAG: check_hostnames
# For security and stability reasons Squid by default checks
# hostnames for Internet standard RFC compliance. If you do not want
# Squid to perform these checks then turn this directive off.
#
#Default:
# check_hostnames on
# TAG: allow_underscore
# Underscore characters is not strictly allowed in Internet hostnames
# but nevertheless used by many sites. Set this to off if you want
# Squid to be strict about the standard.
# This check is performed only when check_hostnames is set to on.
#
#Default:
# allow_underscore on
# TAG: cache_dns_program
# Note: This option is only available if Squid is rebuilt with the
# --disable-internal-dns option
#
# Specify the location of the executable for dnslookup process.
#
#Default:
# cache_dns_program /usr/lib/squid/dnsserver
# TAG: dns_children
# Note: This option is only available if Squid is rebuilt with the
# --disable-internal-dns option
#
# The number of processes spawn to service DNS name lookups.
# For heavily loaded caches on large servers, you should
# probably increase this value to at least 10. The maximum
# is 32. The default is 5.
#
# You must have at least one dnsserver process.
#
#Default:
# dns_children 5
# TAG: dns_retransmit_interval
# Initial retransmit interval for DNS queries. The interval is
# doubled each time all configured DNS servers have been tried.
#
#
#Default:
# dns_retransmit_interval 5 seconds
# TAG: dns_timeout
# DNS Query timeout. If no response is received to a DNS query
# within this time all DNS servers for the queried domain
# are assumed to be unavailable.
#
#Default:
# dns_timeout 2 minutes
# TAG: dns_defnames on|off
# Normally the RES_DEFNAMES resolver option is disabled
# (see res_init(3)). This prevents caches in a hierarchy
# from interpreting single-component hostnames locally. To allow
# Squid to handle single-component names, enable this option.
#
#Default:
# dns_defnames off
# TAG: dns_nameservers
# Use this if you want to specify a list of DNS name servers
# (IP addresses) to use instead of those given in your
# /etc/resolv.conf file.
# On Windows platforms, if no value is specified here or in
# the /etc/resolv.conf file, the list of DNS name servers are
# taken from the Windows registry, both static and dynamic DHCP
# configurations are supported.
#
# Example: dns_nameservers 10.0.0.1 192.172.0.4
#
#Default:
# none
# TAG: hosts_file
# Location of the host-local IP name-address associations
# database. Most Operating Systems have such a file on different
# default locations:
# - Un*X & Linux: /etc/hosts
# - Windows NT/2000: %SystemRoot%\system32\drivers\etc\hosts
# (%SystemRoot% value install default is c:\winnt)
# - Windows XP/2003: %SystemRoot%\system32\drivers\etc\hosts
# (%SystemRoot% value install default is c:\windows)
# - Windows 9x/Me: %windir%\hosts
# (%windir% value is usually c:\windows)
# - Cygwin: /etc/hosts
#
# The file contains newline-separated definitions, in the
# form ip_address_in_dotted_form name [name ...] names are
# whitespace-separated. Lines beginning with an hash (#)
# character are comments.
#
# The file is checked at startup and upon configuration.
# If set to 'none', it won't be checked.
# If append_domain is used, that domain will be added to
# domain-local (i.e. not containing any dot character) host
# definitions.
#
#Default:
# hosts_file /etc/hosts
#
hosts_file /etc/hosts
# TAG: dns_testnames
# The DNS tests exit as soon as the first site is successfully looked up
#
# This test can be disabled with the -D command line option.
#
#Default:
# dns_testnames netscape.com internic.net nlanr.net microsoft.com
# TAG: append_domain
# Appends local domain name to hostnames without any dots in
# them. append_domain must begin with a period.
#
# Be warned there are now Internet names with no dots in
# them using only top-domain names, so setting this may
# cause some Internet sites to become unavailable.
#
#Example:
# append_domain .yourdomain.com
#
#Default:
# none
# TAG: ignore_unknown_nameservers
# By default Squid checks that DNS responses are received
# from the same IP addresses they are sent to. If they
# don't match, Squid ignores the response and writes a warning
# message to cache.log. You can allow responses from unknown
# nameservers by setting this option to 'off'.
#
#Default:
# ignore_unknown_nameservers on
# TAG: ipcache_size (number of entries)
# TAG: ipcache_low (percent)
# TAG: ipcache_high (percent)
# The size, low-, and high-water marks for the IP cache.

#Default:
# fqdncache_size 1024
# MISCELLANEOUS
# -----------------------------------------------------------------------------
# TAG: memory_pools on|off
# If set, Squid will keep pools of allocated (but unused) memory
# available for future use. If memory is a premium on your
# system and you believe your malloc library outperforms Squid
# routines, disable this.
#
#Default:
# memory_pools on
# TAG: memory_pools_limit (bytes)
# Used only with memory_pools on:
# memory_pools_limit 50 MB
#
# If set to a non-zero value, Squid will keep at most the specified
# limit of allocated (but unused) memory in memory pools. All free()
# requests that exceed this limit will be handled by your malloc
# library. Squid does not pre-allocate any memory, just safe-keeps
# objects that otherwise would be free()d. Thus, it is safe to set
# memory_pools_limit to a reasonably high value even if your
# configuration will use less memory.
#
# If set to zero, Squid will keep all memory it can. That is, there
# will be no limit on the total amount of memory used for safe-keeping.
#
# To disable memory allocation optimization, do not set
# memory_pools_limit to 0. Set memory_pools to "off" instead.
#
# An overhead for maintaining memory pools is not taken into account
# when the limit is checked. This overhead is close to four bytes per
# object kept. However, pools may actually _save_ memory because of
# reduced memory thrashing in your malloc library.
#
#Default:
# memory_pools_limit 5 MB
# TAG: forwarded_for on|off
# If set, Squid will include your system's IP address or name
# in the HTTP requests it forwards. By default it looks like
# this:
#
# X-Forwarded-For: 192.1.2.3
#
# If you disable this, it will appear as
#
# X-Forwarded-For: unknown
#
#Default:

#Default:
# reload_into_ims off
# TAG: maximum_single_addr_tries
# This sets the maximum number of connection attempts for a
# host that only has one address (for multiple-address hosts,
# each address is tried once).
#
# The default value is one attempt, the (not recommended)
# maximum is 255 tries. A warning message will be generated
# if it is set to a value greater than ten.
#
# Note: This is in addition to the request re-forwarding which
# takes place if Squid fails to get a satisfying response.
#
#Default:
# maximum_single_addr_tries 1
# TAG: retry_on_error
# If set to on Squid will automatically retry requests when
# receiving an error response. This is mainly useful if you
# are in a complex cache hierarchy to work around access
# control errors.
#
#Default:
# retry_on_error off
# TAG: as_whois_server
# WHOIS server to query for AS numbers. NOTE: AS numbers are
# queried only when Squid starts up, not for every request.
#
#Default:
# as_whois_server whois.ra.net
# as_whois_server whois.ra.net
# TAG: offline_mode
# Enable this option and Squid will never try to validate cached
# objects.
#
#Default:
# offline_mode off
# TAG: uri_whitespace
# What to do with requests that have whitespace characters in the
# URI. Options:
#
# strip: The whitespace characters are stripped out of the URL.
# This is the behavior recommended by RFC2396.
# deny: The request is denied. The user receives an "Invalid
# Request" message.
# allow: The request is allowed and the URI is not changed. The
# whitespace characters remain in the URI. Note the
# whitespace is passed to redirector processes if they
# are in use.
# encode: The request is allowed and the whitespace characters are
# encoded according to RFC1738. This could be considered
# a violation of the HTTP/1.1
# RFC because proxies are not allowed to rewrite URI's.
# chop: The request is allowed and the URI is chopped at the
# first whitespace. This might also be considered a
# violation.
#
#Default:
# uri_whitespace strip
# TAG: coredump_dir
# By default Squid leaves core files in the directory from where
# it was started. If you set 'coredump_dir' to a directory
# that exists, Squid will chdir() to that directory at startup
# and coredump files will be left there.
#
#Default:
# coredump_dir none
#
# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid
# TAG: chroot
# Use this to have Squid do a chroot() while initializing. This
# also causes Squid to fully drop root privileges after
# initializing. This means, for example, if you use a HTTP
# port less than 1024 and try to reconfigure, you will may get an
# error saying that Squid can not open the port.
#
#Default:
# none
# TAG: balance_on_multiple_ip
# Some load balancing servers based on round robin DNS have been
# found not to preserve user session state across requests
# to different IP addresses.
#
# By default Squid rotates IP's per request. By disabling
# this directive only connection failure triggers rotation.
#
#Default:
# balance_on_multiple_ip on
# TAG: pipeline_prefetch
# To boost the performance of pipelined requests to closer
# match that of a non-proxied environment Squid can try to fetch
# up to two requests in parallel from a pipeline.
#
# Defaults to off for bandwidth management and access logging
# reasons.
#
#Default:
# pipeline_prefetch off
# TAG: high_response_time_warning (msec)
# If the one-minute median response time exceeds this value,
# Squid prints a WARNING with debug level 0 to get the
# administrators attention. The value is in milliseconds.
#
#Default:
# high_response_time_warning 0
# TAG: high_page_fault_warning
# If the one-minute average page fault rate exceeds this
# value, Squid prints a WARNING with debug level 0 to get
# the administrators attention. The value is in page faults
# per second.
#
#Default:
# high_page_fault_warning 0
# TAG: high_memory_warning
# If the memory usage (as determined by mallinfo) exceeds
# this amount, Squid prints a WARNING with debug level 0 to get
# the administrators attention.
#
#Default:
# high_memory_warning 0 KB
# TAG: sleep_after_fork (microseconds)
# When this is set to a non-zero value, the main Squid process
# sleeps the specified number of microseconds after a fork()
# system call. This sleep may help the situation where your
# system reports fork() failures due to lack of (virtual)
# memory. Note, however, if you have a lot of child
# processes, these sleep delays will add up and your
# Squid will not service requests for some amount of time
# until all the child processes have been started.
# On Windows value less then 1000 (1 milliseconds) are
# rounded to 1000.
#
#Default:
# sleep_after_fork 0
# TAG: zero_buffers on|off
# Squid by default will zero all buffers before using or reusing them.
# Setting this to 'off' will result in fixed-sized temporary buffers
# not being zero'ed. This may give a performance boost on certain
# platforms but it may result in undefined behaviour at the present
# time.
#
#Default:
# zero_buffers on
# TAG: windows_ipaddrchangemonitor on|off
# On Windows Squid by default will monitor IP address changes and will
# reconfigure itself after any detected event. This is very useful for
# proxies connected to internet with dial-up interfaces.
# In some cases (a Proxy server acting as VPN gateway is one) it could be
# desiderable to disable this behaviour setting this to 'off'.
# Note: after changing this, Squid service must be restarted.
#
#Default:
# windows_ipaddrchangemonitor on
/etc/samba/smb.conf
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
