[SQU] FTP resume is not suported using squid?

I have a redhat 6.2 server running using squid, with windows clients.

Programs like Getright or JetCar(FlashGet) does not support resume
on any FTP site (i get a HTTP 502 Bad Gateway error).

Is it possible to configure SQUID to be able to resume broken
downlaoad? I have to mention that I have a parent cache
configured in SQUID (Europeonline - sattelite to computer one
way link, the second link is a direct modem link to a local ISP).

I have attached my squid.conf file.

# WELCOME TO SQUID 2
# ------------------
#
# This is the default Squid configuration file. You may wish
# to look at http://cache.is.co.za/squid/ for documentation,
# or the Squid home page (http://squid.nlanr.net/) for the FAQ.
#
# 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, whilst 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
# The port number where Squid will listen for HTTP client
# requests. Default is 3128, for httpd-accel mode use port 80.
# May be overridden with -a on the command line.
#
# You may specify multiple ports here, but they MUST all be on
# a single line.
#
http_port 8080

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

# TAG: htcp_port
# The port number where Squid sends and receives ICP requests to
# and from neighbor caches. Default is 4827. To disable use
# "0".
#
#htcp_port 4827
#htcp_port 8080

# TAG: mcast_groups
# This tag specifies a list of multicast groups which your server
# should join to receive multicasted ICP requests.
#
# 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. NLANR has been
# assigned a block of multicast address space for use in Web
# Caching. Plese write to us at nlanr-cache@nlanr.net to receive
# an address for your own use.
#
# If you are unsure about multicast, please read the Multicast
# chapter in the Squid FAQ (http://squid.nlanr.net/Squid/FAQ/).
#
# Usage: mcast_groups 239.128.16.128 224.0.1.20
#
# By default, Squid doesn't listen on any multicast groups.
#
#mcast_groups 239.128.16.128

# TAG: tcp_incoming_address
# 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_incoming_address is used for the HTTP socket which accepts
# connections from clients and other caches.
# 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 behaviour is to not bind to any specific address.
#
# NOTE, udp_incoming_address and udp_outgoing_address can not
# have the same value (unless it is 0.0.0.0) since they both use
# port 3130.
#
#tcp_incoming_address 0.0.0.0

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

# TAG: cache_peer
# To specify other caches in a hierarchy, use the format:
#
# 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
#
# 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 request 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: non-ICP neighbors must be specified as 'parent'.
#
cache_peer 194.177.32.11 parent 8080 0 no-query default login=xxxx:xxxxx
# sorry, but i can't provide you our password
#cache_peer 194.102.172.1 parent 8080 7
# 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.

# 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

# 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
#
#icp_query_timeout 0

# 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.
#
#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.
#
#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.
#
# The default is to directly fetch URLs containing 'cgi-bin' or '?'.
#
#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.
#
# There is no default. We recommend you uncomment 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 PLACES A LIMIT ON ONE ASPECT OF SQUID'S MEMORY
# USAGE. SQUID USES MEMORY FOR OTHER THINGS AS WELL.
# YOUR PROCESS WILL PROBABLY BECOME TWICE OR THREE TIMES
# BIGGER THAN THE VALUE YOU PUT HERE
#
# '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.
#
# The values of cache_mem_low and cache_mem_high (below) can be
# used to tune the use of the memory pool. When the high mark is
# reached, in-transit and hot objects will be released to clear
# space. When an object transfer is completed, it will remain in
# memory only if the current memory usage is below the low water
# mark.
#
# The default is 8 Megabytes.
#
#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 LRU replacement. LRU
# replacement begins when the high-water mark is reached and ends
# when enough objects have been removed and the low-water mark is
# reached. 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.
#
#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.
#
#maximum_object_size 4096 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.
#
#ipcache_size 1024
#ipcache_low 90
#ipcache_high 95

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

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

# TAG: cache_dir
# Usage:
#
# cache_dir Directory-Name Mbytes Level-1 Level2
#
# You can specify multiple cache_dir lines to spread the
# cache among different disk partitions.
#
# '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.
#
# If no 'cache_dir' lines are specified, the following
# default will be used: /var/spool/squid.
#
# '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.
#
#cache_dir /var/spool/squid 100 16 256

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

# TAG: cache_log
# Cache logging file. This is where general information about
# your cache's behaviour goes. You can increase the amount of data
# logged to this file with the "debug_options" tag below.
#
#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 analyse this data, so you can safely
# disable it.
#
#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 the first
# '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 you have more than one 'cache_dir', 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.
#
#cache_swap_log

# 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 analysers use.
#
#emulate_httpd_log off

# 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.
#
#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'.
#
#log_mime_hdrs off

# TAG: useragent_log
# If configured with the "--enable-useragent_log" configure
# option, Squid will write the User-Agent field from HTTP
# requests to the filename specified here. By default
# useragent_log is disabled.
#
#useragent_log none

# TAG: pid_filename
# A filename to write the process-id to. To disable, enter "none".
#
#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".
#
#debug_options ALL,1

# TAG: ident_lookup_access
# A list of ACL elements which, if matched, cause an ident
# (RFC 931) lookup to be performed for this request. For
# example, you might choose to always perform ident lookups
# for your main multi-user Unix boxes, but not for your Macs
# and PCs. By default, ident lookups are not performed for
# any requests.
#
# To enable ident lookups for specific client addresses, you
# can follow this example:
#
# acl ident_aware_hosts src 198.168.1.0/255.255.255.0
# ident_lookup_access allow ident_aware_hosts
# ident_lookup_access deny all
#ident_lookup_access deny all

# 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.
#
#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'.
#
#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
# resonable 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).
#
#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.
#
#ftp_list_width 32

# TAG: cache_dns_program
# Specify the location of the executable for dnslookup process.
#
#cache_dns_program /usr/lib/squid/dnsserver

# TAG: dns_children
# 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.
#
# To disable dnsservers, set this to 0. NOTE, this is very
# strongly discouraged. If you disable dnsservers your Squid
# process will BLOCK on DNS lookups!
#
#dns_children 5

# TAG: dns_defnames on|off
# 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.
#
#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
#
#dns_nameservers none

# TAG: unlinkd_program
# Specify the location of the executable for file deletion process.
# This isn't needed if you are using async-io since it's handled by
# a thread.
#
#unlinkd_program /usr/lib/squid/unlinkd

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

# 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.
#
#redirect_program 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.
#
#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.
#redirect_rewrites_host_header on

# 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
#
#authenticate_program none

# 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.
#
#authenticate_children 5

# TAG: authenticate_ttl
# The time a checked username/password combination remains cached
# (default 3600). If a wrong password is given for a cached user,
# the user gets removed from the username/password cache forcing
# a revalidation.
#
#authenticate_ttl 3600

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

# TAG: wais_relay_host
# TAG: wais_relay_port
# Relay WAIS request to host (1st arg) at port (2 arg).
#
#wais_relay_host localhost
#wais_relay_port 8000

# TAG: request_size (KB)
# Maximum allowed request size in kilobytes. If people are using
# POST to upload files, then set this to the largest acceptable
# filesize plus a few extra kbytes.
#
#request_size 100 KB

# TAG: refresh_pattern
# usage: refresh_pattern [-i] regex min percent max [options]
#
# By default, regular expressions are CASE-SENSITIVE. To make

#
# min and max are specified in MINUTES.
# percent is an integer number.
#
# 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.
#
# Please see the file doc/Release-Notes-1.1.txt for a full

#
# FRESH if expires < now, else STALE
# STALE if age > max
# FRESH if lm-factor < percent, else STALE
# FRESH if age < min
# else STALE

# 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 month.
#
# Specify a number here, followed by units of time. For example:
# 1 week
# 3.5 days
# 4 months
# 2.2 hours
#
#reference_age 1 month

# 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.

# 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.
#
#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.

#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
# client requested. (default)

# 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).
#
#connect_timeout 120 seconds

# TAG: siteselect_timeout time-units
# For URN to multiple URL's URL selection
#
#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.
#
#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.
#
#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 alot 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.
#
#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."
#
#half_closed_clients on

# TAG: pconn_timeout
# Timeout for idle persistent connections to servers and other
# proxies.
#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.
#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.

#
# NOTE on default values:
#
# If there are no "access" lines present, the default is to allow
# 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

# 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 configuration:
#http_access allow manager localhost
#http_access deny manager

# 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.

#
#cache_mgr root

# TAG: cache_effective_user
# TAG: cache_effective_group
#
# If the cache is run as root, it will change its effective/real

# TAG: visible_hostname
# If you want to present a special hostname in error messages, etc,

# 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 annoucement message is NOT
# SENT unless you enable it with 'announce_period' below.
#
# The announcement message includes your hostname, plus the
# following information from this configuration file:
#
# http_port
# icp_port
# cache_mgr
#
# All current information is processed regularly and made
# available on the Web at http://ircache.nlanr.net/Cache/Tracker/.

# TAG: announce_period
# This is how frequently to send cache announcements. The
# default is `0' which disables sending the announcement
# messages.
#
# To enable announcing your cache, just uncomment the line
# below.
#
#announce_period 1 day

# TAG: announce_host
# TAG: announce_file
# TAG: announce_port
# announce_host and announce_port set the hostname and port
# number where the registration message will be sent.
#
# Hostname will default to 'tracker.ircache.net' and port will
# default default to 3131. If the 'filename' argument is given,
# the contents of that file will be included in the announce
# message.

#announce_host tracker.ircache.net
#announce_port 3131

# HTTPD-ACCELERATOR OPTIONS
# -----------------------------------------------------------------------------

# TAG: httpd_accel_host
# TAG: httpd_accel_port
# If you want to run Squid as an httpd accelerator, define the
# host name and port number where the real HTTP server is.
#
# If you want virtual host support then specify the hostname
# as "virtual".
#
# NOTE: enabling httpd_accel_host disables proxy-caching and
# ICP. If you want these features enabled also, then set
# the 'httpd_accel_with_proxy' option.
#
#httpd_accel_host hostname
#httpd_accel_port port

# TAG: httpd_accel_with_proxy on|off
# If you want to use Squid as both a local httpd accelerator
# and as a proxy, change this to 'on'.
#
#httpd_accel_with_proxy off

# TAG: httpd_accel_uses_host_header on|off
# HTTP/1.1 requests include a Host: header which is basically the
# hostname from the URL. Squid can be an accelerator for
# different HTTP servers by looking at this header. However,
# Squid does NOT check the value of the Host header, so it opens
# a big security hole. We recommend that this option remain
# disabled unless you are sure of what you are doing.
#
# However, you will need to enable this option if you run Squid
# as a transparent proxy. Otherwise, virtual servers which
# require the Host: header will not be properly cached.
#httpd_accel_uses_host_header off

# MISCELLANEOUS
# -----------------------------------------------------------------------------

# TAG: dns_testnames
# The DNS tests exit as soon as the first site is successfully looked up
#
# If you want to disable DNS tests, do not comment out or delete this
# list. Instead use the -D command line option
#
#dns_testnames netscape.com internic.net nlanr.net microsoft.com

# TAG: logfile_rotate
# Specifies the number of logfile rotations to make when you
# type 'squid -k rotate'. The default is 10, which will rotate
# with extensions 0 through 9. Setting logfile_rotate to 0 will
# disable the rotation, but the logfiles are still closed and
# re-opened. This will enable you to rename the logfiles
# yourself just before sending the rotate signal.
#
# Note, the 'squid -k rotate' command normally sends a USR1
# signal to the running squid process. In certain situations
# (e.g. on Linux with Async I/O), USR1 is used for other
# purposes, so -k rotate uses another signal. It is best to get
# in the habit of using 'squid -k rotate' instead of 'kill -USR1
# <pid>'.

#logfile_rotate 10

# TAG: append_domain
# Appends local domain name to hostnames without any dots in
# them. append_domain must begin with a period.
#
#append_domain .yourdomain.com

# TAG: tcp_recv_bufsize (bytes)
# Size of receive buffer to set for TCP sockets. Probably just
# as easy to change your kernel's default. Set to zero to use
# the default buffer size.
#
#tcp_recv_bufsize 0 bytes

# TAG: err_html_text
# HTML text to include in error messages. Make this a "mailto"
# URL to your admin address, or maybe just a link to your
# organizations Web page.
#
# To include this in your error messages, you must rewrite
# the error template files (found in the "errors" directory).
# Wherever you want the 'err_html_text' line to appear,
# insert a %L tag in the error template file.
#err_html_text

# TAG: deny_info
# Usage: deny_info err_page_name acl
# Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
#
# This can be used to return a ERR_ page for requests which
# do not pass the 'http_access' rules. A single ACL will cause
# the http_access check to fail. If a 'deny_info' line exists
# for that ACL then Squid returns a corresponding error page.
#
# You may use ERR_ pages that come with Squid or create your own pages
# and put them into the configured errors/ directory.

# TAG: memory_pools on|off
# If set, Squid will keep pools of allocated (but unused) memory
# available for future use. If memory is a premium on your
# system and you believe your malloc library outperforms Squid
# routines, disable this.
#
#memory_pools on

# TAG: memory_pools_limit (bytes)
# Used only with memory_pools on:
# memory_pools_limit 50 MB
#
# If set to a non-zero value, Squid will keep at most the specified
# limit of allocated (but unused) memory in memory pools. All free()
# requests that exceed this limit will be handled by your malloc
# library. Squid does not pre-allocate any memory, just safe-keeps
# objects that otherwise would be free()d. Thus, it is safe to set
# memory_pools_limit to a reasonably high value even if your
# configuration will use less memory.
#
# If not set (default) or set to zero, Squid will keep all memory it
# can. That is, there will be no limit on the total amount of memory
# used for safe-keeping.
#
# To disable memory allocation optimization, do not set
# memory_pools_limit to 0. Set memory_pools to "off" instead.
#
# An overhead for maintaining memory pools is not taken into account
# when the limit is checked. This overhead is close to four bytes per
# object kept. However, pools may actually _save_ memory because of
# reduced memory thrashing in your malloc library.

# TAG: forwarded_for on|off
# If set, Squid will include your system's IP address or name
# in the HTTP requests it forwards. By default it looks like
# this:
#
# X-Forwarded-For: 192.1.2.3
#
# If you disable this, it will appear as
#
# X-Forwarded-For: unknown
#
#forwarded_for on

# TAG: log_icp_queries on|off
# If set, ICP queries are logged to access.log. You may wish
# do disable this if your ICP load is VERY high to speed things
# up or to simplify log analysis.
#
#log_icp_queries on

# TAG: icp_hit_stale on|off
# If you want to return ICP_HIT for stale cache objects, set this
# option to 'on'. If you have sibling relationships with caches
# in other administrative domains, this should be 'off'. If you only
# have sibling relationships with caches under your control, then
# it is probably okay to set this to 'on'.

# entries will be deleted until the low mark is reached.
#
#netdb_low 900
#netdb_high 1000

# TAG: netdb_ping_period
# The minimum period for measuring a site. There will be at
# least this much delay between successive pings to the same
# network. The default is five minutes.
#
#netdb_ping_period 5 minutes

# TAG: query_icmp on|off
# If you want to ask your peers to include ICMP data in their ICP
# replies, enable this option.
#
# If your peer has configured Squid (during compilation) with
# '--enable-icmp' then that peer will send ICMP pings to origin server
# sites of the URLs it receives. If you enable this option then the
# ICP replies from that peer will include the ICMP data (if available).
# Then, when choosing a parent cache, Squid will choose the parent with
# the minimal RTT to the origin server. When this happens, the
# hierarchy field of the access.log will be
# "CLOSEST_PARENT_MISS". This option is off by default.
#
#query_icmp off

# TAG: test_reachability on|off
# When this is 'on', ICP MISS replies will be ICP_MISS_NOFETCH

# database, or has a zero RTT.
#
#test_reachability off

# TAG: buffered_logs on|off
# Some log files (cache.log, useragent.log) are written with
# stdio functions, and as such they can be buffered or
# unbuffered. By default they will be unbuffered. Buffering them
# can speed up the writing slightly (though you are unlikely to
# need to worry).
#buffered_logs off

# TAG: reload_into_ims on|off
# When you enable this option, client no-cache or ``reload''

# see also refresh_pattern for a more selective approach.
#
#reload_into_ims off

# TAG: always_direct
# Usage: always_direct allow|deny [!]aclname ...
#
# Here you can use ACL elements to specify requests which should
# ALWAYS be forwarded directly to origin servers. For example,
# to always directly forward requests for local servers use
# something like:
#
# acl local-servers dstdomain my.domain.net
# always_direct allow local-servers
#
# To always forward FTP requests directly, use
#
                acl FTP proto FTP
                always_direct allow FTP
#
# NOTE: There is a similar, but opposite option named
# 'never_direct'. You need to be aware that "always_direct deny
# foo" is NOT the same thing as "never_direct allow foo". You
# may need to use a deny rule to exclude a more-specific case of
# some other rule. Example:
#
# acl local-external dstdomain external.foo.net
# acl local-servers dstdomain foo.net
# always_direct deny local-external
# always_direct allow local-servers
#
# This option replaces some v1.1 options such as local_domain
# and local_ip.

# TAG: never_direct
# Usage: never_direct allow|deny [!]aclname ...
#
# never_direct is the opposite of always_direct. Please read
# the description for always_direct if you have not already.
#
# With 'never_direct' you can use ACL elements to specify
# requests which should NEVER be forwarded directly to origin
# servers. For example, to force the use of a proxy for all
# requests, except those in your local domain use something like:
#
# acl local-servers dstdomain foo.net
# acl all src 0.0.0.0/0.0.0.0
# never_direct deny local-servers
# never_direct allow all
#
# or if squid is inside a firewall and there is local intranet
# servers inside the firewall then use something like:
#
# acl local-intranet dstdomain foo.net
# acl local-external dstdomain external.foo.net
# always_direct deny local-external
# always_direct allow local-intranet
# never_direct allow all
#
# This option replaces some v1.1 options such as inside_firewall
# and firewall_ip.

never_direct allow all

# TAG: anonymize_headers
# Usage: anonymize_headers allow|deny header_name ...
#
# This option replaces the old 'http_anonymizer' option with
# something that is much more configurable. You may now
# specify exactly which headers are to be allowed, or which
# are to be removed from outgoing requests.
#
# There are two methods of using this option. You may either
# allow specific headers (thus denying all others), or you
# may deny specific headers (thus allowing all others).
#
# For example, to achieve the same behaviour as the old
# 'http_anonymizer standard' option, you should use:
#
# anonymize_headers deny From Referer Server
# anonymize_headers deny User-Agent WWW-Authenticate Link
#
# Or, to reproduce the old 'http_anonymizer paranoid' feature
# you should use:
#
# anonymize_headers allow Allow Authorization Cache-Control
# anonymize_headers allow Content-Encoding Content-Length
# anonymize_headers allow Content-Type Date Expires Host
# anonymize_headers allow If-Modified-Since Last-Modified
# anonymize_headers allow Location Pragma Accept Charset
# anonymize_headers allow Accept-Encoding Accept-Language
# anonymize_headers allow Content-Language Mime-Version
# anonymize_headers allow Retry-After Title Connection
# anonymize_headers allow Proxy-Connection
#
# NOTE: You can not mix "allow" and "deny". All 'anonymize_headers'
# lines must have the same second argument.
#
# By default, all headers are allowed (no anonymizing is
# performed).
#
#anonymize_headers

# TAG: fake_user_agent
# If you filter the User-Agent header with 'anonymize_headers' it
# may cause some Web servers to refuse your request. Use this to
# fake one up. For example:
#
# fake_user_agent Nutscrape/1.0 (CP/M; 8-bit)
# (credit to Paul Southworth pauls@etext.org for this one!)
#
#fake_user_agent none

# TAG: icon_directory
# Where the icons are stored. These are normally kept in
# /usr/lib/squid/icons

# TAG: error_directory
# Directory where the error files are read from.
# /usr/lib/squid/errors contains sets of error files
# in different languages. The default error directory
# is /etc/squid/errors, which is a link to one of these
# error sets.
# If you wish to create your own versions of the error files,
# either to customise them to suit your
# language or company copy the template english files to another
# directory and point this tag at them.
#
#error_directory /etc/squid/errors

# TAG: minimum_retry_timeout (seconds)
# This specifies the minimum connect timeout, for when the
# connect timeout is reduced to compensate for the availability
# of multiple IP addresses.
#
# When a connection to a host is initiated, and that host has
# several IP addresses, the default connection timeout is reduced
# by dividing it by the number of addresses. So, a site with 15
# addresses would then have a timeout of 8 seconds for each
# address attempted. To avoid having the timeout reduced to the
# point where even a working host would not have a chance to
# respond, this setting is provided. The default, and the
# minimum value, is five seconds, and the maximum value is sixty
# seconds, or half of connect_timeout, whichever is greater and
# less than connect_timeout.
#
#minimum_retry_timeout 5 seconds

# TAG: maximum_single_addr_tries
# This sets the maximum number of connection attempts for a
# host that only has one address (for multiple-address hosts,
# each address is tried once).
#
# The default value is three tries, the (not recommended)
# maximum is 255 tries. A warning message will be generated
# if it is set to a value greater than ten.
#
#maximum_single_addr_tries 3

# TAG: snmp_port
# Squid can now serve statistics and status information via SNMP.
# By default it listens to port 3401 on the machine. If you don't
# wish to use SNMP, set this to '-1'.
#
# NOTE: SNMP support requires use the --enable-snmp configure
# command line option.
#snmp_port 3401

# TAG: forward_snmpd_port
# This configures whether we should be forwarding SNMP requests
# to another snmpd. The reason for putting this piece of
# functionality into Squid was to enable access to the system's
# installed snmpd with minimal changes. This option is turned
# off by default, check with your /etc/services for your system's
# snmp port (usually 161). We do not use getservbyname() to
# allow you to set Squid into port 161 and your system's snmpd to
# another port by changing /etc/services.
#
# WARNING: Because of Squid acting as a proxy snmpd for system
# you have to do security checks on THIS snmpd for all objects.
# Check your snmp_config_file.
#forward_snmpd_port 0

# TAG: snmp_access
# Allowing or denying access to the SNMP port.
#
# All access to the agent is denied by default.
# usage:
#
# snmp_access allow|deny [!]aclname ...
#
#Example:
#snmp_access allow public localhost
#snmp_access deny all

# TAG: snmp_incoming_address
# TAG: snmp_outgoing_address
# Just like 'udp_incoming_address' above, but for the SNMP port.
#
# snmp_incoming_address is used for the SNMP socket receiving
# messages from SNMP agents.
# snmp_outgoing_address is used for SNMP packets returned to SNMP
# agents.
#
# The default behaviour is to not bind to any specific address.
#
# NOTE, snmp_incoming_address and snmp_outgoing_address can not have
# the same value since they both use port 3130.
#
#snmp_incoming_address 0.0.0.0
#snmp_outgoing_address 0.0.0.0

# TAG: as_whois_server
# WHOIS server to query for AS numbers. NOTE: AS numbers are
# queried only when Squid starts up, not for every request.

# DELAY POOL PARAMETERS (all require DELAY_POOLS compilation option)
# -----------------------------------------------------------------------------

# TAG: delay_pools
# This represents the number of delay pools to be used. For example,
# if you have one class 2 delay pool and one class 3 delays pool, you
# have a total of 2 delay pools.
#
#delay_pools 0

# TAG: delay_class
# This defines the class of each delay pool. There must be exactly one
# delay_class line for each delay pool. For example, to define two
# delay pools, one of class 2 and one of class 3, the settings above
# and here would be:
#
#delay_pools 2 # 2 delay pools
#delay_class 1 2 # pool 1 is a class 2 pool
#delay_class 2 3 # pool 2 is a class 3 pool
#
# The delay pool classes are:
#
# class 1 Everything is limited by a single aggregate
# bucket.
#
# class 2 Everything is limited by a single aggregate
# bucket as well as an "individual" bucket chosen
# from bits 25 through 32 of the IP address.
#
# class 3 Everything is limited by a single aggregate
# bucket as well as a "network" bucket chosen
# from bits 17 through 24 of the IP address and a
# "individual" bucket chosen from bits 17 through
# 32 of the IP address.
#
# NOTE: If an IP address is a.b.c.d
# -> bits 25 through 32 are "d"
# -> bits 17 through 24 are "c"
# -> bits 17 through 32 are "c * 256 + d"

# TAG: delay_access
# This is used to determine which delay pool a request falls into.
# The first matched delay pool is always used, ie, if a request falls
# into delay pool number one, no more delay are checked, otherwise the
# rest are checked in order of their delay pool number until they have
# all been checked. For example, if you want some_big_clients in delay
# pool 1 and lotsa_little_clients in delay pool 2:
#
#delay_access 1 allow some_big_clients
#delay_access 1 deny all
#delay_access 2 allow lotsa_little_clients
#delay_access 2 deny all

# TAG: delay_parameters
# This defines the parameters for a delay pool. Each delay pool has
# a number of "buckets" associated with it, as explained in the
# description of delay_class. For a class 1 delay pool, the syntax is:
#
#delay_parameters pool aggregate
#
# For a class 2 delay pool:
#
#delay_parameters pool aggregate individual
#
# For a class 3 delay pool:
#
#delay_parameters pool aggregate network individual
#
# The variables here are:
#
# pool a pool number - ie, a number between 1 and the
# number specified in delay_pools as used in
# delay_class lines.
#
# aggregate the "delay parameters" for the aggregate bucket
# (class 1, 2, 3).
#
# individual the "delay parameters" for the individual
# buckets (class 2, 3).
#
# network the "delay parameters" for the network buckets
# (class 3).
#
# A pair of delay parameters is written restore/maximum, where restore is
# the number of bytes (not bits - modem and network speeds are usually
# quoted in bits) per second placed into the bucket, and maximum is the
# maximum number of bytes which can be in the bucket at any time.
#
# For example, if delay pool number 1 is a class 2 delay pool as in the
# above example, and is being used to strictly limit each host to 64kbps
# (plus overheads), with no overall limit, the line is:
#
#delay_parameters 1 -1/-1 8000/8000
#
# Note that the figure -1 is used to represent "unlimited".
#
# And, if delay pool number 2 is a class 3 delay pool as in the above
# example, and you want to limit it to a total of 256kbps (strict limit)
# with each 8-bit network permitted 64kbps (strict limit) and each
# individual host permitted 4800bps with a bucket maximum size of 64kb
# to permit a decent web page to be downloaded at a decent speed
# (if the network is not being limited due to overuse) but slow down
# large downloads more significantly:
#
#delay_parameters 2 32000/32000 8000/8000 600/64000
#
# There must be one delay_parameters line for each delay pool.

# TAG: delay_initial_bucket_level (percent, 0-100)
# The initial bucket percentage is used to determine how much is put
# in each bucket when squid starts, is reconfigured, or first notices
# a host accessing it (in class 2 and class 3, individual hosts and
# networks only have buckets associated with them once they have been
# "seen" by squid).
#
#delay_initial_bucket_level 50

# TAG: incoming_icp_average

# Are you crazy? Don't even think about adjusting these unless
# you understand the algorithms in comm_select.c first!

# TAG: max_open_disk_fds
# TAG: offline_mode
# Enable this option and Squid will never try to validate cached
# objects.

# TAG: uri_whitespace
# What to do with requests that have whitespace characters in the
# URI. Options:
#
# deny: The request is denied. The user receives an "Invalid
# Request" message.
# allow: The request is allowed and the URI is not changed. The
# whitespace characters remain in the URI. Note the
# whitespace is passed to redirector processes if they
# are in use.
# encode: The request is allowed and the whitespace characters are
# encoded according to RFC1738. This could be considered
# a violation of the HTTP/1.1
# RFC because proxies are not allowed to rewrite URI's.
# chop: The request is allowed and the URI is chopped at the
# first whitespace. This might also be considered a
# violation.
#uri_whitespace deny

# TAG: broken_posts
# A list of ACL elements which, if matched, causes Squid to send
# a extra CRLF pair after the body of a PUT/POST request.
#
# Some HTTP servers has broken implementations of PUT/POST,
# and rely on a extra CRLF pair sent by some WWW clients.
#
# Quote from RFC 2068 section 4.1 on this matter:
#
# Note: certain buggy HTTP/1.0 client implementations generate an
# extra CRLF's after a POST request. To restate what is explicitly
# forbidden by the BNF, an HTTP/1.1 client must not preface or follow
# a request with an extra CRLF.
#
#acl buggy_server url_regex ^http://....
#broken_posts allow buggy_server

# TAG: mcast_miss_addr
# If you enable this option, every "cache miss" URL will
# be sent out on the specified multicast address.
#
# Do not enable this option unless you are are absolutely
# certain you understand what you are doing.

# TAG: mcast_miss_port
# This is the port number to be used in conjuction with
# 'mcast_miss_addr'.

# TAG: mcast_miss_encode_key
# The URLs that are sent in the multicast miss stream are
# encrypted. This is the encryption key.

# TAG: prefer_direct
# By default, if the ICP, HTCP, Cache Digest, etc. techniques
# do not yield a parent cache, Squid gives higher preference
# to forwarding the request direct to origin servers, rather
# than selecting a parent cache anyway.
#
# If you want Squid to give higher precedence to a parent
# cache, instead of going direct, then turn this option off.
#prefer_direct on

# TAG: strip_query_terms
# By default, Squid strips query terms from requested URLs before
# logging. This protects your user's privacy.
#strip_query_terms on

# TAG: coredump_dir
# By default Squid leaves core files in the first cache_dir
# directory. If you set 'coredump_dir' to a directory
# that exists, Squid will chdir() to that directory at startup
# and coredump files will be left there.
