# WELCOME TO SQUID 3.0.STABLE15
# ----------------------------
#
# 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.
# Ports flagged 'transparent' or 'tproxy' have authentication disabled.
#
# === 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.
# If you use an authenticator, make sure you have 1 acl of type proxy_auth.
#
# By default, the basic authentication scheme is not used unless a
# program is specified.
#
# If you want to use the traditional NCSA proxy authentication, set
# this line to something like
#
# auth_param basic program /usr/local/squid/libexec/ncsa_auth /usr/local/squid/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 password verifications are
# done via a (slow) network you are likely to need lots of
# authenticator processes.
# auth_param basic children 5
#
# "concurrency" concurrency
# The number of concurrent requests the helper can process.
# The default of 0 is used for helpers who only supports
# one request at a time. Setting this 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.
# auth_param basic concurrency 0
#
# "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). There is no default.
# 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
# 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.
#
# "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
#
# === 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, set this line to
# something like
#
# auth_param digest program /usr/local/squid/bin/digest_pw_auth /usr/local/squid/etc/digpass
#
# "children" numberofchildren
# The number of authenticator processes to spawn (no default).
# If you start too few Squid will have to wait for them to
# process a backlog of H(A1) calculations, slowing it down.
# When the H(A1) calculations are done via a (slow) network
# you are likely to need lots of authenticator processes.
# auth_param digest children 5
#
# "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). There is no default.
# auth_param digest realm Squid proxy-caching web server
#
# "nonce_garbage_interval" timeinterval
# Specifies the interval that nonces that have been issued
# to client_agent's are checked for validity.
#
# "nonce_max_duration" timeinterval
# Specifies the maximum length of time a given nonce will be
# valid for.
#
# "nonce_max_count" number
# Specifies the maximum number of times a given nonce can be
# used.
#
# "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)). Default 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.
#
# "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 on a GET request.
#
# === NTLM scheme options follow ===
#
# "program" cmdline
# Specify the command for the external NTLM authenticator.
# Such a program reads exchanged NTLMSSP packets with
# the browser via Squid until authentication is completed.
# If you use an NTLM authenticator, make sure you have 1 acl
# of type proxy_auth. By default, the NTLM authenticator_program
# is not used.
#
# auth_param ntlm program /usr/local/squid/bin/ntlm_auth
#
# "children" numberofchildren
# The number of authenticator processes to spawn (no default).
# 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
# 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 ntlm keep_alive on
#
# === Options for configuring the NEGOTIATE auth-scheme follow ===
#
# "program" cmdline
# Specify the command for the external Negotiate authenticator.
# This protocol is used in Microsoft Active-Directory enabled setups with
# the Microsoft Internet Explorer or Mozilla Firefox browsers.
# Its main purpose is to exchange credentials with the Squid proxy
# using the Kerberos mechanisms.
# If you use a Negotiate authenticator, make sure you have at least one acl
# of type proxy_auth active. By default, the negotiate authenticator_program
# is not used.
# The only supported program for this role is the ntlm_auth
# program distributed as part of Samba, version 4 or later.
#
# auth_param negotiate program /usr/local/squid/bin/ntlm_auth --helper-protocol=gss-spnego
#
# "children" numberofchildren
# The number of authenticator processes to spawn (no default).
# If you start too few Squid will have to wait for them to
# process a backlog of credential verifications, slowing it
# down. When crendential 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>

# 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
# 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 acl helper 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.
# cache=n result cache size, 0 is unbounded (default)
# grace=n 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
# %PORT Requested port
# %PATH Requested URL path
# %METHOD Request method
# %MYADDR Squid interface address
# %MYPORT Squid http_port number
# %PATH Requested URL-path (including query-string if any)
# %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 "Header"
# %{Hdr:member} HTTP request header "Hdr" list member "member"
# %{Hdr:;member}
# HTTP request header list member using ; as
# list separator. ; can be any non-alphanumeric
# character.
#
# 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)
# password= The users password (for login= cache_peer option)
# message= Message describing the reason. Available as %o
# in error pages
# tag= Apply a tag to a request (for both ERR and OK results)
# Only sets a tag, does not alter existing tags.
# 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.
#
#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 TYPES AVAILABLE *****
#
# 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, Windows, 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, from client IP
# acl aclname dstdomain .foo.com ... # Destination server from URL
# acl aclname srcdom_regex [-i] \.foo\.com ... # regex matching client name
# acl aclname dstdom_regex [-i] \.foo\.com ... # 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 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 time [day-abbrevs] [h1:m1-h2:m2]
# # day-abbrevs:
# # S - Sunday
# # M - Monday
# # T - Tuesday
# # W - Wednesday
# # H - Thursday
# # F - Friday
# # 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 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 http_status 200 301 500- 400-403 ... # status code in reply
#
# 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 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/intercepting 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 [-i] 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 [-i] 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.
#
# acl aclname external class_name [arguments...]
# # external ACL lookup via a helper class defined by the
# # external_acl_type directive.
#
# 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

# TAG: ident_lookup_access
# A list of ACL elements which, if matched, cause an ident

# TAG: reply_body_max_size size [acl acl...]
# This option specifies the maximum size of a reply body. 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 where
# all (if any) listed ACLs are true 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.
#
# WARNING: A maximum size smaller than the size of squid's error messages
# will cause an infinite loop and crash squid. Ensure that the smallest
# non-zero value you use is greater that the maximum header size plus
# the size of your largest error page.

# 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 -a command line option may be used to specify additional
# port(s) where Squid listens for proxy request. Such ports will
# be plain proxy ports with no options.
#
# You may specify multiple socket addresses on multiple lines.
#
# Options:
#
# transparent Support for transparent interception of

#
# type: either 'parent', 'sibling', or 'multicast'.
#
# proxy-port: The port number where the cache listens for proxy
# requests.
#
# icp-port: Used for querying neighbor caches about
# objects. To have a non-ICP neighbor
# specify '7' for the ICP port and make sure the

# front-end-https[=on|auto]
#
# 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 'basetime=n' to specify a base amount to
# be subtracted from round trip times of parents.
# It is subtracted before division by weight in calculating
# which parent to fectch from. If the rtt is less than the
# base time the rtt is set to a minimal value.
#
# 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 'background-ping' to only send ICP queries to this
# neighbor infrequently. This is used to keep the neighbor
# round trip time updated and is usually used in
# conjunction with weighted-round-robin.
#
# 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 'weighted-round-robin' to define a set of parents
# which should be used in a round-robin fashion with the
# frequency of each parent being based on the round trip
# time. Closer parents are used more often.
# Usually used for background-ping parents.
#
# 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.
#
# 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.
#
# '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.
#
# '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.
# This only works for the Basic HTTP authentication scheme.
# Note: To combine this with proxy_auth both proxies 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 set htcp_access expicitly. The default of
# deny all will prevent peer traffic.
#
# use 'htcp-oldsquid' to send HTCP to old Squid versions
# You MUST also set htcp_access expicitly. The default of
# deny all will prevent peer traffic.
#
# 'originserver' causes this parent peer to be contacted as
# a origin server. Meant to be used in accelerator setups.
#
# 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 '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
# combined file containing both the certificate and the key.
#
# use sslversion=1|2|3|4 to specify the SSL version to use

# 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.

# 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.

# 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.
#
# 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:
#
# NP: COSS filesystem in 3.0 has been deemed too unstable for
# production use and has thus been removed from this 3.0
# STABLE release. We hope that it can be made usable again
# in a future release.
#
# 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
