ta meio bagunçado mas e esse aí...
aceito sugestões para dar uma melhorada nele....

Obrigado..

# WELCOME TO SQUID 2
# ------------------
#
# 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.
#

# NETWORK OPTIONS
# -----------------------------------------------------------------------------

# TAG: http_port
# Usage: port
#
# hostname:port
# 1.2.3.4:port
#
# 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, then 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.
#
# The default port number is 3128.
#
# If you are running Squid in accelerator mode, then you
# probably want to listen on port 80 also, or instead.
#
# The -a command line option will override the *first* port
# number listed here. That option will NOT override an IP
# address, however.
#
# You may specify multiple socket addresses on multiple lines.
#
#Default:
http_port 3128

# TAG: icp_port
# The port number where Squid sends and receives ICP queries to
# and from neighbor caches. Default is 3130. To disable use
# "0". May be overridden with -u on the command line.
#
#Default:
icp_port 3130

# TAG: htcp_port
# Note: This option is only available if Squid is rebuilt with the
# --enable-htcp option
#
# The port number where Squid sends and receives HTCP queries to
# and from neighbor caches. Default is 4827. To disable use
# "0".
#
# To enable this option, you must use --enable-htcp with the
# configure script.
#
#Default:
# htcp_port 4827

# 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: tcp_outgoing_address
# TAG: udp_incoming_address
# TAG: udp_outgoing_address
# Usage: tcp_incoming_address 10.20.30.40
# udp_outgoing_address fully.qualified.domain.name
#
# tcp_outgoing_address is used for connections made to remote
# servers and other caches.
# udp_incoming_address is used for the ICP socket receiving packets
# from other caches.
# udp_outgoing_address is used for ICP packets sent out to other
# caches.
#
# The default behavior is to not bind to any specific address.
#
# A *_incoming_address value of 0.0.0.0 indicates that Squid should
# listen on all available interfaces.
#
# If udp_outgoing_address is set to 255.255.255.255 (the default)
# then it will use the same socket as udp_incoming_address. Only
# change this if you want to have ICP queries sent using another
# address than where this Squid listens for ICP queries from other
# caches.
#
# NOTE, udp_incoming_address and udp_outgoing_address can not
# have the same value since they both use port 3130.
#
# NOTE, tcp_incoming_address has been removed. You can now
# specify IP addresses on the 'http_port' line.
#
#Default:
# tcp_outgoing_address 255.255.255.255
# udp_incoming_address 0.0.0.0
# udp_outgoing_address 255.255.255.255

# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
# -----------------------------------------------------------------------------

# TAG: cache_peer
# To specify other caches in a hierarchy, use the format:
#
# cache_peer hostname type http_port icp_port
#
# For example,
#
# # proxy icp
# # hostname type port port options
# # -------------------- -------- ----- ----- -----------
# cache_peer parent.foo.net parent 3128 3130 [proxy-only]
# cache_peer sib1.foo.net sibling 3128 3130 [proxy-only]
# cache_peer sib2.foo.net sibling 3128 3130 [proxy-only]
#
# 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
# neighbor machine has the UDP echo port
# enabled in its /etc/inetd.conf file.
#
# options: proxy-only
# weight=n
# ttl=n
# no-query
# default
# round-robin
# multicast-responder
# closest-only
# no-digest
# no-netdb-exchange
# no-delay
# login=user:password
# connect-timeout=nn
# digest-url=url
# allow-miss
#
# use 'proxy-only' to specify that objects fetched
# from this cache should not be saved locally.
#
# use 'weight=n' to specify a weighted parent.
# The weight must be an integer. The default weight
# is 1, larger weights are favored more.
#
# 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." You should probably
# only use 'default' in situations where you cannot
# use ICP with your parent cache(s).
#
# 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.
#
# 'multicast-responder' indicates that 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.
#
# 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)
#
# NOTE: non-ICP neighbors must be specified as 'parent'.
#
#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 domainname
# with '!' means that 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: neighbor_type_domain
# usage: neighbor_type_domain 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 parent cache.foo.org 3128 3130
# neighbor_type_domain cache.foo.org sibling .com .net
# neighbor_type_domain cache.foo.org sibling .au .de
#
#Default:
# none

# 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: 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

# 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.
#
#We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# TAG: no_cache
# A list of ACL elements which, if matched, cause the reply to
# immediately removed from the cache. 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.
#
#We recommend you to use the following two lines.
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY

# OPTIONS WHICH AFFECT THE CACHE SIZE
# -----------------------------------------------------------------------------

# 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 16 MB

# 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 120
cache_swap_high 125

# 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.
#
#Default:
# maximum_object_size 4096 KB

# 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_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: 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:
ipcache_size 1024
ipcache_low 90
ipcache_high 95

# TAG: fqdncache_size (number of entries)
# Maximum number of FQDN cache entries.
#
#Default:
# fqdncache_size 1024

# 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/techr...PL-98-173.html.
#
#Default:
# cache_replacement_policy lru

# 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

# LOGFILE PATHNAMES AND CACHE DIRECTORIES
# -----------------------------------------------------------------------------

# 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. Most
# everyone will want to use "ufs" as the type. If you are using
# Async I/O (--enable async-io) on Linux or Solaris, then you may
# want to try "aufs" as the type. Async IO support may be
# buggy, however, so beware.
#
# 'Directory' is a top-level directory where cache swap
# files will be stored. If you want to use an entire disk
# for caching, then 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.
#
# '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 recevies some replies. Default is 72
#
# Common options:
#
# read-only, this cache_dir is read only.
#
# 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.
#
#Default:
cache_dir ufs /var/spool/squid 100 16 256

# TAG: cache_access_log
# Logs the client request activity. Contains an entry for
# every HTTP and ICP queries received.
#
#Default:
cache_access_log /var/log/squid/access.log

# TAG: cache_log
# Cache logging file. This is where general information about
# your cache's behavior goes. You can increase the amount of data
# 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_log
# Location for the cache "swap.log." This log 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 then 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
# then 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, then these log files will NOT correspond to
# the correct 'cache_dir' entry (unless you manually rename
# them). We recommend that you do NOT use this option. It is
# better to keep these log files in each 'cache_dir' directory.
#
#Default:
# none

# 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 that 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 /etc/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'.
#
#Default:
# log_mime_hdrs off

# TAG: useragent_log
# Note: This option is only available if Squid is rebuilt with the
# --enable-useragent-log option
#
# Squid will write the User-Agent field from HTTP requests
# to the filename specified here. By default useragent_log
# is disabled.
#
#Default:
# none

# TAG: referer_log
# Note: This option is only available if Squid is rebuilt with the
# --enable-referer-log option
#
# Squid will write the Referer field from HTTP requests to the
# filename specified here. By default referer_log is disabled.
#
#Default:
# none

# TAG: pid_filename
# A filename to write the process-id to. To disable, enter "none".
#
#Default:
pid_filename /var/run/squid.pid

# TAG: debug_options
# Logging options are set as section,level where each source file
# is assigned a unique section. Lower levels result in less
# output, Full debugging (level 9) can result in a very large
# log file, so be careful. The magic word "ALL" sets debugging
# levels for all sections. We recommend normally running with
# "ALL,1".
#
#Default:
debug_options ALL,1

# TAG: log_fqdn on|off
# Turn this on if you wish to log fully qualified domain names
# in the access.log. To do this Squid does a DNS lookup of all
# IP's connecting to it. This can (in some situations) increase
# latency, which makes your cache seem slower for interactive
# browsing.
#
#Default:
# log_fqdn off

# TAG: client_netmask
# A netmask for client addresses in logfiles and cachemgr output.
# Change this to protect the privacy of your cache clients.
# A netmask of 255.255.255.0 will log all IP's in that range with
# the last digit set to '0'.
#
#Default:
# client_netmask 255.255.255.255

# OPTIONS FOR EXTERNAL SUPPORT PROGRAMS
# -----------------------------------------------------------------------------

# TAG: ftp_user
# 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 [email protected]
#
# The reason why this is domainless by default is that 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 that the email address is valid
# (for example perl.com).
#
#Default:
ftp_user Squid

# TAG: ftp_list_width
# Sets the width of ftp listings. This should be set to fit in
# the width of a standard browser. Setting this too small
# can cut off long filenames when browsing ftp sites.
#
#Default:
#ftp_li st_width 32

# TAG: ftp_passive
# If your firewall does not allow Squid to use passive
# connections, then turn off this option.
#
#Default:
ftp_passive on

# TAG: ftp_sanitycheck
# For security and data integrity reasons Squid by default performs
# sanity checks of the addresses of FTP data connections ensure the
# data connection is to the requested server. If you need to allow
# FTP connections to servers using another IP address for the data
# connection then turn this off.
#
#Default:
#
#ftp_sanitycheck on
ftp_sanitycheck off

# 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/

# 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 then all DNS servers for the queried domain
# is assumed to be unavailable.
#
#Default:
# dns_timeout 5 minutes

# TAG: dns_defnames on|off
# Note: This option is only available if Squid is rebuilt with the
# --disable-internal-dns option
#
# Normally the 'dnsserver' disables the RES_DEFNAMES resolver
# option (see res_init(3)). This prevents caches in a hierarchy
# from interpreting single-component hostnames locally. To allow
# dnsserver 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.
#
# Example: dns_nameservers 10.0.0.1 192.172.0.4
#
#Default:
# none

# TAG: diskd_program
# Specify the location of the diskd executable.
# Note that this is only useful if you have compiled in
# diskd as one of the store io modules.
#
#Default:
# diskd_program /usr/lib/squid/diskd

# TAG: unlinkd_program
# Specify the location of the executable for file deletion process.
#
#Default:
# unlinkd_program /usr/lib/squid/unlinkd

# TAG: pinger_program
# Note: This option is only available if Squid is rebuilt with the
# --enable-icmp option
#
# Specify the location of the executable for the pinger process.
# This is only useful if you configured Squid (during compilation)
# with the '--enable-icmp' option.
#
#Default:
# pinger_program /usr/lib/squid/

# TAG: redirect_program
# Specify the location of the executable for the URL redirector.
# Since they can perform almost any function there isn't one included.
# See the Release-Notes for information on how to write one.
# By default, a redirector is not used.
#
#Default:
# none

# TAG: redirect_children
# The number of redirector processes to spawn. If you start
# too few Squid will have to wait for them to process a backlog of
# URLs, slowing it down. If you start too many they will use RAM
# and other system resources.
#
#Default:
# redirect_children 5

# TAG: redirect_rewrites_host_header
# By default Squid rewrites any Host: header in redirected
# requests. If you are running a accelerator then this may
# not be a wanted effect of a redirector.
#
#Default:
# redirect_rewrites_host_header on

# TAG: redirector_access
# If defined, this access list specifies which requests are
# sent to the redirector processes. By default all requests
# are sentSSS.
#
#Default:
# none

# TAG: authenticate_program
# 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. If you use an authenticator,
# make sure you have 1 acl of type proxy_auth. By default, the
# authenticator_program is not used.
#
# If you want to use the traditional proxy authentication,
# jump over to the ../auth_modules/NCSA directory and
# type:
# % make
# % make install
#
# Then, set this line to something like
#
# authenticate_program /usr/bin/ncsa_auth /usr/etc/passwd
#
#Default:
#auth_param basic program /usr/sbin/ncsa_auth /etc/squid/passwd

# TAG: authenticate_children
# The number of authenticator processes to spawn (default 5). If you
# start too few Squid will have to wait for them to process a backlog
# of usercode/password verifications, slowing it down. When password
# verifications are done via a (slow) network you are likely to need
# lots of authenticator processes.
#
#Default:
authenticate_children 5

# TAG: authenticate_ttl
# The time a checked username/password combination remains cached.
# If a wrong password is given for a cached user, the user gets
# removed from the username/password cache forcing a revalidation.
#
#Default:
authenticate_ttl 2 hour

# TAG: authenticate_ip_ttl
# With this option you control how long a proxy authentication
# will be bound to a specific IP address. If a request using
# the same user name is received during this time then access
# will be denied and both users are required to reauthenticate
# them selves. The idea behind this is to make it annoying
# for people to share their password to their friends, but
# yet allow a dialup user to reconnect on a different dialup
# port.
#
# The default is 0 to disable the check. Recommended value
# if you have dialup users are no more than 60 seconds to allow
# the user to redial without hassle. If all your users are
# stationary then higher values may be used.
#
# See also authenticate_ip_ttl_is_strict
#
#Default:
# authenticate_ip_ttl 0 seconds

# TAG: authenticate_ip_ttl_is_strict
# This option makes authenticate_ip_ttl a bit stricted. With this
# enabled authenticate_ip_ttl will deny all access from other IP
# addresses until the TTL has expired, and the IP address "owning"
# the userid will not be forced to reauthenticate.
#
#Default:
# authenticate_ip_ttl_is_strict on

# OPTIONS FOR TUNING THE CACHE
# -----------------------------------------------------------------------------

# TAG: wais_relay_host
# TAG: wais_relay_port
# Relay WAIS request to host (1st arg) at port (2 arg).
#
#Default:
# wais_relay_port 0

# TAG: request_header_max_size (KB)
# This specifies the maximum size for HTTP headers in a request.
# Request headers are usually relatively small (about 512 bytes).
# Placing a limit on the request header size will catch certain
# bugs (for example with persistent connections) and possibly
# buffer-overflow or denial-of-service attacks.
#
#Default:
# request_header_max_size 10 KB

# TAG: request_body_max_size (KB)
# This specifies the maximum size for an HTTP request body.
# In other words, the maximum size of a PUT/POST request.
# A user who attempts to send a request with a body larger
# than this limit receives an "Invalid Request" error message.
# If you set this parameter to a zero, there will be no limit
# imposed.
#
#Default:
# request_body_max_size 1 MB

# TAG: reply_body_max_size (KB)
# 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. The reply 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 this parameter, 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.
#
# NOTE: 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

# 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.
#
# options: overrsde-expire
# override-lastmod
# reload-into-ims
# ignore-reload
#
# override-expire enforces min age even if the server
# sent a Expires: header. Doing this 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 was 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.
#
# Please see the file doc/Release-Notes-1.1.txt for a full
# description of Squid's refresh algorithm. Basically a
# cached object is: (the order is changed from 1.1.X)
#
# FRESH if expires < now, else STALE
# STALE if age > max
# FRESH if lm-factor < percent, else STALE
# FRESH if age < min
# else STALE
#
# The refresh_pattern lines are checked in the order listed here.
# The first entry which matches is used. If none of the entries
# match, then the default will be used.
#
# Note, you must uncomment all the default lines if you want
# to change one. The default setting is only active if none is
# used.
#
#Default:
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern . 0 20% 4320

# TAG: reference_age
# As a part of normal operation, Squid performs Least Recently
# Used removal of cached objects. The LRU age for removal is
# computed dynamically, based on the amount of disk space in
# use. The dynamic value can be seen in the Cache Manager 'info'
# output.
#
# The 'reference_age' parameter defines the maximum LRU age. For
# example, setting reference_age to '1 week' will cause objects
# to be removed if they have not been accessed for a week or
# more. The default value is one year.
#
# Specify a number here, followed by units of time. For example:
# 1 week
# 3.5 days
# 4 months
# 2.2 hours
#
# NOTE: this parameter is not used when using the enhanced
# replacement policies, GDSH or LFUDA.
#
#Default:
# reference_age 1 year

# TAG: quick_abort_min (KB)
# TAG: quick_abort_max (KB)
# TAG: quick_abort_pct (percent)
# The cache can be configured to continue downloading aborted
# requests. 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
# quick_abort values to the amount of data transfered until
# then.
#
# If the transfer has less than 'quick_abort_min' KB remaining,
# it will finish the retrieval. Setting 'quick_abort_min' to -1
# will disable the quick_abort feature.
#
# If the transfer has more than 'quick_abort_max' KB remaining,
# it will abort the retrieval.
#
# If more than 'quick_abort_pct' of the transfer has completed,
# it will finish the retrieval.
#
#Default:
# quick_abort_min 16 KB
# quick_abort_max 16 KB
# quick_abort_pct 95

# TAG: negative_ttl time-units
# Time-to-Live (TTL) for failed requests. Certain types of
# failures (such as "connection refused" and "404 Not Found") are
# negatively-cached for a configurable amount of time. The
# default is 5 minutes. Note that this is different from
# negative caching of DNS lookups.
#
#Default:
# negative_ttl 5 minutes

# TAG: positive_dns_ttl time-units
# Time-to-Live (TTL) for positive caching of successful DNS lookups.
# Default is 6 hours (360 minutes). If you want to minimize the
# use of Squid's ipcache, set this to 1, not 0.
#
#Default:
# positive_dns_ttl 6 hours

# TAG: negative_dns_ttl time-units
# Time-to-Live (TTL) for negative caching of failed DNS lookups.
#
#Default:
# negative_dns_ttl 5 minutes

# 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 then 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
# beginning so that it may cache the result. (2.0 style)
#
# A value of 0 causes Squid to never fetch more than the
# client requested. (default)
#
#Default:
# range_offset_limit 0 KB

# TIMEOUTS
# -----------------------------------------------------------------------------

# TAG: connect_timeout time-units
# Some systems (notably Linux) can not be relied upon to properly
# time out connect(2) requests. Therefore the Squid process
# enforces its own timeout on server connections. This parameter
# specifies how long to wait for the connect to complete. The
# default is two minutes (120 seconds).
#
#Default:
# connect_timeout 2 minutes

# 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: siteselect_timeout time-units
# For URN to multiple URL's URL selection
#
#Default:
# siteselect_timeout 4 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 connection
# establishment. For persistent connections, wait this long
# after the previous request completes.
#
#Default:
# request_timeout 30 seconds

# TAG: client_lifetime time-units
# The maximum amount of time that 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, pconn_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 120 seconds

# TAG: ident_timeout
# Maximum time to wait for IDENT requests. If this is too high,
# and you enabled 'ident_lookup', then you might be susceptible
# to denial-of-service by having many ident requests going at
# once.
#
# 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.
#
# This option may be disabled by using --disable-ident with
# the configure script.
#
#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

# If Squid is not started as root, the default is to keep the
# current UID/GID. Note that if Squid is not started as root then
# you cannot set http_port to a value lower than 1024.

#Default:
cache_effective_user squid squid
cache_effective_group squid

# TAG: visible_hostname
# If you want to present a special hostname in error messages, etc,
# then 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' then you must give each machine a different
# 'unique_hostname' so that forwarding loops can be detected.
#
#Default:
# none

# TAG: hostname_aliases
# A list of other DNS names that your cache has.
#
#Default:
# none

# 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.
