# 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.
#
# If you run Squid on a dual-homed machine with an internal
# and an external interface then we recommend you to specify the
# internal address:port in http_port. This way Squid will only be
# visible on the internal address.
#
#Default:
http_port 3128

# TAG: https_port
# Usage: [ip:]port cert=certificate.pem [key=key.pem] [options...]
#
# The socket address where Squid will listen for HTTPS client
# requests.
#
# This is really only useful for situations where you are running
# squid in accelerator mode and you want to do the SSL work at the
# accelerator level.
#
# You may specify multiple socket addresses on multiple lines,
# each with their own SSL certificate and/or options.
#
# Options:
#
# cert= Path to SSL certificate (PEM format)
#
# key= Path to SSL private key file (PEM format)
# if not specified, the certificate file is
# assumed to be a combined certificate and
# key file
#
# version= The version of SSL/TLS supported
# 1 automatic (default)
# 2 SSLv2 only
# 3 SSLv3 only
# 4 TLSv1 only
#
# cipher= Colon separated list of supported ciphers
#
# options= Varions SSL engine options. The most important
# being:
# NO_SSLv2 Disallow the use of SSLv2
# NO_SSLv3 Disallow the use of SSLv3
# NO_TLSv1 Disallow the use of TLSv1
# See src/ssl_support.c or OpenSSL documentation
# for a more complete list.
#
#Default:
# none

# TAG: ssl_unclean_shutdown
# Some browsers (especially MSIE) bugs out on SSL shutdown
# messages.
#
#Default:
# ssl_unclean_shutdown off

# 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".
#
#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: udp_incoming_address
# TAG: udp_outgoing_address
# 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 udp_incoming_address value of 0.0.0.0 indicates that Squid should
# listen for UDP messages 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.
#
#Default:
# 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 | PASS | *:password
# connect-timeout=nn
# digest-url=url
# allow-miss
# max-conn
#
# 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.
# Note: The string can include URL escapes (i.e. %20 for
# spaces). This also means that % must be written as %%.
#
# use 'login=PASS' if users must authenticate against
# the upstream proxy. This will pass the users credentials
# as they are to the peer proxy. This only works for the
# Basic HTTP authentication sheme. Note: To combine this
# with proxy_auth both proxies must share the same user
# database as HTTP only allows for one proxy login.
# Also be warned that 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' to limit the amount of connections Squid
# may open to this 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 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.
#
#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 8 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 90
# cache_swap_high 95

# 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/techrepo ... 8-173.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]
#
# cache_dir diskd Maxobjsize Directory-Name MB L1 L2 Q1 Q2
#
# 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 eanble 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, 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. 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 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. To disable, enter "none".
#
#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 wwwuser@somewhere.net
#
# 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_list_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

# 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.
# 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: under
# Un*X it's by default in /etc/hosts MS-Windows NT/2000 places
# that in %SystemRoot%(by default
# c:\winnt)\system32\drivers\etc\hosts, while Windows 9x/ME
# places that in %windir%(usually c:\windows)\hosts
#
# The file contains newline-separated definitions, in the
# form ip_address_in_dotted_form name [name ...] names are
# whitespace-separated. lines beginnng 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

# 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.
#
#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 FAQ (section 15) 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 an 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 sent.
#
#Default:
# none

# TAG: auth_param
# This is used to pass parameters to the various authentication
# schemes.
# format: auth_param scheme parameter [setting]
#
# auth_param basic program /usr/bin/ncsa_auth /usr/etc/passwd
# would tell the basic authentication scheme it's program parameter.
#
# The order that authentication prompts are presented to the client_agent
# is dependant 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 file below. If other browsers
# have difficulties (don't recognise the schemes offered even if you are using
# basic) then 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.
#
# === 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. If you use an authenticator,
# make sure you have 1 acl of type proxy_auth. By default, the
# authenticate_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
#
# auth_param basic program /usr/bin/ncsa_auth /usr/etc/passwd
#
# "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 usercode/password 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
#
# "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
# that setting this high does not impact your susceptability
# 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.
#
# === 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 base64 encoded.
# See rfc 2616 for the definition of H(A1). If you use an
# authenticator, make sure you have 1 acl of type proxy_auth.
# By default, authentication is not used.
#
# If you want to use build an authenticator,
# jump over to the ../digest_auth_modules 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/bin/digest_auth_pw /usr/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 increment-by-1 behaviour for
# nonce counts (on - the default), or strictly incrementing
# (off - for use when useragents generate nonce counts that
# occasionally miss 1 (ie, 1,2,4,6)).
#
# === NTLM scheme options follow ===
#
# "program" cmdline
# Specify the command for the external ntlm authenticator.
# Such a program reads a line containing the uuencoded NEGOTIATE
# and replies with the ntlm CHALLENGE, then waits for the
# response and answers with "OK" or "ERR" in an endless loop.
# 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/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 crendential verifications are done via a (slow)
# network you are likely to need lots of authenticator
# processes.
# auth_param ntlm children 5
#
# "max_challenge_reuses" number
# The maximum number of times a challenge given by a ntlm
# authentication helper can be reused. Increasing this number
# increases your exposure to replay attacks on your network.
# 0 means use the challenge only once. (disable challenge
# caching) See max_ntlm_challenge_lifetime for more information.
# auth_param ntlm max_challenge_reuses 0
#
# "max_challenge_lifetime" timespan
# The maximum time period that a ntlm challenge is reused
# over. The actual period will be the minimum of this time
# AND the number of reused challenges.
# auth_param ntlm max_challenge_lifetime 2 minutes
#
#Recommended minimum configuration:
#auth_param digest program <uncomment and complete this line>
#auth_param digest children 5
#auth_param digest realm Squid proxy-caching web server
#auth_param digest nonce_garbage_interval 5 minutes
#auth_param digest nonce_max_duration 30 minutes

#auth_param basic program <uncomment and complete this line>
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours

# TAG: authenticate_cache_garbage_interval
# The time period between garbage collection across the
# username cache. This is a tradeoff between memory utilisation
# (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: 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)
# concurrency=n Concurrency level / number of processes spawn
# to service external acl lookups of this type.
# cache=n result cache size, 0 is unbounded (default)
#
# FORMAT specifications
#
# %LOGIN Authenticated user login name
# %IDENT Ident user name
# %SRC Client IP
# %DST Requested host
# %PROTO Requested protocol
# %PORT Requested port
# %METHOD Request method
# %{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.
#
# In addition, 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)
# error= Error description (only defined for ERR results)
#
# Keyword values need to be enclosed in quotes if they may contain
# whitespace, or the whitespace escaped using \. Any quotes or \
# characters within the keyword value must be \ escaped.
#
#Default:
# none


# 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 (the default), there will
# be no limit imposed.
#
#Default:
# request_body_max_size 0 KB

# 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: override-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.
#
# 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
#
# 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.
#
#Suggested default:
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern . 0 20% 4320

# TAG: quick_abort_min (KB)
# TAG: quick_abort_max (KB)
# 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
# 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.
#
# 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.
#
# If you do not want any retrieval to continue after the client
# has aborted, set both 'quick_abort_min' and 'quick_abort_max'
# to '0 KB'.
#
# If you want retrievals to always continue if they are being
# cached then set 'quick_abort_min' to '-1 KB'.
#
#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: 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 1 minute

# 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, 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 120 seconds

# 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, then 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

# when using "file", the file should contain one item per line
#
# acltype is one of the types described below
#
# 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 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. 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
# 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 proto HTTP FTP ...
# acl aclname method GET POST ...
# acl aclname browser [-i] regexp ...
# # pattern match on User-Agent header
# 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 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
# # authenticate_program).
# #
# # WARNING: proxy_auth can't be used in a transparent proxy. It
# # collides with any authentication done by origin servers. It may
# # seem like it works at first, but it doesn't.
#
# 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 then 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 then 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-type1 ...
# # regex match agains the mime type of the request generated
# # by the client. Can be used to detect file upload or some
# # types HTTP tunelling requests.
# # NOTE: This does NOT match the reply. You cannot use this
# # to match the returned file type.
#
# acl aclname rep_mime_type mime-type1 ...
# # regex match against the mime type of the reply recieved by
# # squid. Can be used to detect file download or some
# # types HTTP tunelling 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 acl_name external class_name [arguments...]
# # external ACL lookup via a helper class defined by the
# # external_acl_type directive.
#
#Examples:
#acl myexample dst_as 1241
#acl password proxy_auth REQUIRED
#acl fileupload req_mime_type -i ^multipart/form-data$
#acl javascript rep_mime_type -i ^application/x-javascript$
#
#Recommended minimum configuration:
acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443 563
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT

# TAG: http_access
# Allowing or Denying access based on defined access lists
#
# Access to the HTTP port:
# http_access allow|deny [!]aclname ...
#
# NOTE on default values:
#
# If there are no "access" lines present, the default is to deny
# the request.
#
# If none of the "access" lines cause a match, the default is the
# opposite of the last line in the list. If the last line was
# deny, then the default is allow. Conversely, if the last line
# is allow, the default will be deny. For these reasons, it is a
# good idea to have an "deny all" or "allow all" entry at the end
# of your access lists to avoid potential confusion.
#
#Default:
# http_access deny all
#
#Recommended minimum configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager
# Deny requests to unknown ports
http_access deny !Safe_ports
# Deny CONNECT to other than SSL ports
http_access deny CONNECT !SSL_ports
#
# We strongly recommend to uncomment the following to protect innocent
# web applications running on the proxy server who think that the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

# Exampe rule allowing access from your local networks. Adapt
# to list your (internal) IP networks from where browsing should
# be allowed
acl our_networks src 192.168.0.1/200
http_access allow our_networks

# And finally deny all other access to this proxy
http_access allow localhost
http_access deny all

# TAG: http_reply_access
# Allow replies to client requests. This is complementary to http_access.
#
# http_reply_access allow|deny [!] aclname ...
#
# NOTE: if there are no access lines present, the default is to allow
# all replies
#
#
If none of the access lines cause a match, then the opposite of the
# last line will apply. Thus it is good practice to end the rules
# with an "allow all" or "deny all" entry.
#
#Default:
# http_reply_access allow all
#
#Recommended minimum configuration:
#
# Insert your own rules here.
#
#
# and finally allow by default
http_reply_access allow all

# TAG: icp_access
# Allowing or Denying access to the ICP port based on defined
# access lists
#
# icp_access allow|deny [!]aclname ...
#
# See http_access for details
#
#Default:
# icp_access deny all
#
#Allow ICP queries from everyone
icp_access allow all

# TAG: miss_access
# Use to force your neighbors to use you as a sibling instead of
# a parent. For example:
#
# acl localclients src 172.16.0.0/16
# miss_access allow localclients
# miss_access deny !localclients
#
# This means that only your local clients are allowed to fetch
# MISSES and all other clients can only fetch HITS.
#
# By default, allow all clients who passed the http_access rules
# to fetch MISSES from us.
#
#Default setting:
# miss_access allow all

# 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 com

Have you configured anything in configuration file because it looks like brand new. Create acl for allowing your network and then see... For basic configuration please see HERE[url]

for ftp proxy you need to use different software. squid only deals with port 80 traffic. for more info on configuring squid i have already gave you link above.
