####################################################################
#
#
# I. INTRODUCTION
# ===============
#
# This file holds Privoxy's main configuration. Privoxy detects
# configuration changes automatically, so you don't have to restart
# it unless you want to load a different configuration file.
#
# The configuration will be reloaded with the first request after
# the change was done, this request itself will still use the old
# configuration, though. In other words: it takes two requests before
# you see the result of your changes. Requests that are dropped due
# to ACL don't trigger reloads.
#
# When starting Privoxy on Unix systems, give the location of this
# file as last argument. On Windows systems, Privoxy will look for
# this file with the name 'config.txt' in the current working directory
# of the Privoxy process.
#
#
# II. FORMAT OF THE CONFIGURATION FILE
# ====================================
#
# Configuration lines consist of an initial keyword followed by a
# list of values, all separated by whitespace (any number of spaces
# or tabs). For example,
#
# actionsfile default.action
#
# Indicates that the actionsfile is named 'default.action'.
#
# The '#' indicates a comment. Any part of a line following a '#'
# is ignored, except if the '#' is preceded by a '\'.
#
# Thus, by placing a # at the start of an existing configuration
# line, you can make it a comment and it will be treated as if it
# weren't there. This is called "commenting out" an option and can
# be useful. Removing the # again is called "uncommenting".
#
# Note that commenting out an option and leaving it at its default
# are two completely different things! Most options behave very
# differently when unset. See the "Effect if unset" explanation in
# each option's description for details.
#
# Long lines can be continued on the next line by using a `\' as the
# last character.
#
#
#
# 1. LOCAL SET-UP DOCUMENTATION
# ==============================
#
# If you intend to operate Privoxy for more users than just yourself,
# it might be a good idea to let them know how to reach you, what
# you block and why you do that, your policies, etc.
#
#
#
# 1.1. user-manual
# =================
#
# Specifies:
#
# Location of the Privoxy User Manual.
#
# Type of value:
#
# A fully qualified URI
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# http://www.privoxy.org/version/user-manual/ will be used,
# where version is the Privoxy version.
#
# Notes:
#
# The User Manual URI is the single best source of information on
# Privoxy, and is used for help links from some of the internal
# CGI pages. The manual itself is normally packaged with the
# binary distributions, so you probably want to set this to a
# locally installed copy.
#
# Examples:
#
# The best all purpose solution is simply to put the full local
# PATH to where the User Manual is located:
#
# user-manual /usr/share/doc/privoxy/user-manual
#
# The User Manual is then available to anyone with
# access to Privoxy, by following the built-in URL:
# http://config.privoxy.org/user-manual/ (or the shortcut:
# http://p.p/user-manual/).
#
# If the documentation is not on the local system, it can be
# accessed from a remote server, as:
#
# user-manual http://example.com/privoxy/user-manual/
#
# WARNING!!!
#
# If set, this option should be the first option in the config
# file, because it is used while the config file is being read.
#
user-manual /usr/share/doc/privoxy/user-manual
#
#
# 1.2. trust-info-url
# ====================
#
# Specifies:
#
# A URL to be displayed in the error page that users will see if
# access to an untrusted page is denied.
#
# Type of value:
#
# URL
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# No links are displayed on the "untrusted" error page.
#
# Notes:
#
# The value of this option only matters if the experimental trust
# mechanism has been activated. (See trustfile below.)
#
# If you use the trust mechanism, it is a good idea to write
# up some on-line documentation about your trust policy and to
# specify the URL(s) here. Use multiple times for multiple URLs.
#
# The URL(s) should be added to the trustfile as well, so users
# don't end up locked out from the information on why they were
# locked out in the first place!
#
#trust-info-url http://www.example.com/why_we_block.html
#trust-info-url http://www.example.com/what_we_allow.html
#
#
# 1.3. admin-address
# ===================
#
# Specifies:
#
# An email address to reach the Privoxy administrator.
#
# Type of value:
#
# Email address
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# No email address is displayed on error pages and the CGI user
# interface.
#
# Notes:
#
# If both admin-address and proxy-info-url are unset, the whole
# "Local Privoxy Support" box on all generated pages will not
# be shown.
#
#admin-address privoxy-admin@example.com
#
#
# 1.4. proxy-info-url
# ====================
#
# Specifies:
#
# A URL to documentation about the local Privoxy setup,
# configuration or policies.
#
# Type of value:
#
# URL
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# No link to local documentation is displayed on error pages and
# the CGI user interface.
#
# Notes:
#
# If both admin-address and proxy-info-url are unset, the whole
# "Local Privoxy Support" box on all generated pages will not
# be shown.
#
# This URL shouldn't be blocked ;-)
#
#proxy-info-url http://www.example.com/proxy-service.html
#
#
# 2. CONFIGURATION AND LOG FILE LOCATIONS
# ========================================
#
# Privoxy can (and normally does) use a number of other files for
# additional configuration, help and logging. This section of the
# configuration file tells Privoxy where to find those other files.
#
# The user running Privoxy, must have read permission for all
# configuration files, and write permission to any files that would
# be modified, such as log files and actions files.
#
#
#
# 2.1. confdir
# =============
#
# Specifies:
#
# The directory where the other configuration files are located.
#
# Type of value:
#
# Path name
#
# Default value:
#
# /etc/privoxy (Unix) or Privoxy installation dir (Windows)
#
# Effect if unset:
#
# Mandatory
#
# Notes:
#
# No trailing "/", please.
#
confdir /etc/privoxy
#
#
# 2.2. templdir
# ==============
#
# Specifies:
#
# An alternative directory where the templates are loaded from.
#
# Type of value:
#
# Path name
#
# Default value:
#
# unset
#
# Effect if unset:
#
# The templates are assumed to be located in confdir/template.
#
# Notes:
#
# Privoxy's original templates are usually overwritten with each
# update. Use this option to relocate customized templates that
# should be kept. As template variables might change between
# updates, you shouldn't expect templates to work with Privoxy
# releases other than the one they were part of, though.
#
#templdir .
#
#
# 2.3. logdir
# ============
#
# Specifies:
#
# The directory where all logging takes place (i.e. where the
# logfile is located).
#
# Type of value:
#
# Path name
#
# Default value:
#
# /var/log/privoxy (Unix) or Privoxy installation dir (Windows)
#
# Effect if unset:
#
# Mandatory
#
# Notes:
#
# No trailing "/", please.
#
logdir /var/log/privoxy
#
#
# 2.4. actionsfile
# =================
#
# Specifies:
#
# The actions file(s) to use
#
# Type of value:
#
# Complete file name, relative to confdir
#
# Default values:
#
# match-all.action # Actions that are applied to all sites and maybe overruled later on.
#
# default.action # Main actions file
#
# user.action # User customizations
#
# Effect if unset:
#
# No actions are taken at all. More or less neutral proxying.
#
# Notes:
#
# Multiple actionsfile lines are permitted, and are in fact
# recommended!
#
# The default values are default.action, which is the "main"
# actions file maintained by the developers, and user.action,
# where you can make your personal additions.
#
# Actions files contain all the per site and per URL configuration
# for ad blocking, cookie management, privacy considerations,
# etc. There is no point in using Privoxy without at least one
# actions file.
#
# Note that since Privoxy 3.0.7, the complete filename, including
# the ".action" extension has to be specified. The syntax change
# was necessary to be consistent with the other file options and
# to allow previously forbidden characters.
#
actionsfile match-all.action # Actions that are applied to all sites and maybe overruled later on.
actionsfile default.action # Main actions file
actionsfile user.action # User customizations
#
#
# 2.5. filterfile
# ================
#
# Specifies:
#
# The filter file(s) to use
#
# Type of value:
#
# File name, relative to confdir
#
# Default value:
#
# default.filter (Unix) or default.filter.txt (Windows)
#
# Effect if unset:
#
# No textual content filtering takes place, i.e. all +filter{name}
# actions in the actions files are turned neutral.
#
# Notes:
#
# Multiple filterfile lines are permitted.
#
# The filter files contain content modification rules that use
# regular expressions. These rules permit powerful changes on the
# content of Web pages, and optionally the headers as well, e.g.,
# you could try to disable your favorite JavaScript annoyances,
# re-write the actual displayed text, or just have some fun
# playing buzzword bingo with web pages.
#
# The +filter{name} actions rely on the relevant filter (name)
# to be defined in a filter file!
#
# A pre-defined filter file called default.filter that contains a
# number of useful filters for common problems is included in the
# distribution. See the section on the filter action for a list.
#
# It is recommended to place any locally adapted filters into a
# separate file, such as user.filter.
#
filterfile default.filter
filterfile user.filter # User customizations
#
#
# 2.6. logfile
# =============
#
# Specifies:
#
# The log file to use
#
# Type of value:
#
# File name, relative to logdir
#
# Default value:
#
# Unset (commented out). When activated: logfile (Unix) or
# privoxy.log (Windows).
#
# Effect if unset:
#
# No logfile is written.
#
# Notes:
#
# The logfile is where all logging and error messages are
# written. The level of detail and number of messages are set with
# the debug option (see below). The logfile can be useful for
# tracking down a problem with Privoxy (e.g., it's not blocking
# an ad you think it should block) and it can help you to monitor
# what your browser is doing.
#
# Depending on the debug options below, the logfile may be a
# privacy risk if third parties can get access to it. As most
# users will never look at it, Privoxy 3.0.7 and later only log
# fatal errors by default.
#
# For most troubleshooting purposes, you will have to change that,
# please refer to the debugging section for details.
#
# Your logfile will grow indefinitely, and you will probably
# want to periodically remove it. On Unix systems, you can do
# this with a cron job (see "man cron"). For Red Hat based Linux
# distributions, a logrotate script has been included.
#
# Any log files must be writable by whatever user Privoxy is
# being run as (on Unix, default user id is "privoxy").
#
logfile logfile
#
#
# 2.7. trustfile
# ===============
#
# Specifies:
#
# The name of the trust file to use
#
# Type of value:
#
# File name, relative to confdir
#
# Default value:
#
# Unset (commented out). When activated: trust (Unix) or trust.txt
# (Windows)
#
# Effect if unset:
#
# The entire trust mechanism is disabled.
#
# Notes:
#
# The trust mechanism is an experimental feature for building
# white-lists and should be used with care. It is NOT recommended
# for the casual user.
#
# If you specify a trust file, Privoxy will only allow access to
# sites that are specified in the trustfile. Sites can be listed
# in one of two ways:
#
# Prepending a ~ character limits access to this site only (and
# any sub-paths within this site), e.g. ~www.example.com allows
# access to ~www.example.com/ features/news.html, etc.
#
# Or, you can designate sites as trusted referrers, by prepending
# the name with a + character. The effect is that access to
# untrusted sites will be granted -- but only if a link from
# this trusted referrer was used to get there. The link target
# will then be added to the "trustfile" so that future, direct
# accesses will be granted. Sites added via this mechanism do
# not become trusted referrers themselves (i.e. they are added
# with a ~ designation). There is a limit of 512 such entries,
# after which new entries will not be made.
#
# If you use the + operator in the trust file, it may grow
# considerably over time.
#
# It is recommended that Privoxy be compiled with the
# --disable-force, --disable-toggle and --disable-editor options,
# if this feature is to be used.
#
# Possible applications include limiting Internet access for
# children.
#
#trustfile trust
#
#
# 3. DEBUGGING
# =============
#
# These options are mainly useful when tracing a problem. Note that
# you might also want to invoke Privoxy with the --no-daemon command
# line option when debugging.
#
#
#
# 3.1. debug
# ===========
#
# Specifies:
#
# Key values that determine what information gets logged.
#
# Type of value:
#
# Integer values
#
# Default value:
#
# 0 (i.e.: only fatal errors (that cause Privoxy to exit) are logged)
#
# Effect if unset:
#
# Default value is used (see above).
#
# Notes:
#
# The available debug levels are:
debug 1 # Log the destination for each request Privoxy let through. See also debug 1024.
# debug 2 # show each connection status
# debug 4 # show I/O status
# debug 8 # show header parsing
# debug 16 # log all data written to the network
# debug 32 # debug force feature
# debug 64 # debug regular expression filters
# debug 128 # debug redirects
# debug 256 # debug GIF de-animation
# debug 512 # Common Log Format
# debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
# debug 2048 # CGI user interface
# debug 4096 # Startup banner and warnings.
# debug 8192 # Non-fatal errors
# debug 32768 # log all data read from the network
#
#
# To select multiple debug levels, you can either add them or
# use multiple debug lines.
#
# A debug level of 1 is informative because it will show you each
# request as it happens. 1, 1024, 4096 and 8192 are recommended
# so that you will notice when things go wrong. The other levels
# are probably only of interest if you are hunting down a specific
# problem. They can produce a hell of an output (especially 16).
#
# Privoxy used to ship with the debug levels recommended above
# enabled by default, but due to privacy concerns 3.0.7 and later
# are configured to only log fatal errors.
#
# If you are used to the more verbose settings, simply enable
# the debug lines below again.
#
# If you want to use pure CLF (Common Log Format), you should set
# "debug 512" ONLY and not enable anything else.
#
# Privoxy has a hard-coded limit for the length of log messages. If
# it's reached, messages are logged truncated and marked with
# "... [too long, truncated]".
#
# Please don't file any support requests without trying to
# reproduce the problem with increased debug level first. Once
# you read the log messages, you may even be able to solve the
# problem on your own.
#
#debug 1 # Log the destination for each request Privoxy let through.
#debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
#debug 4096 # Startup banner and warnings
debug 8192 # Non-fatal errors
#debug 32768 # Non-fatal errors
#
#
# 3.2. single-threaded
# =====================
#
# Specifies:
#
# Whether to run only one server thread.
#
# Type of value:
#
# None
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# Multi-threaded (or, where unavailable: forked) operation,
# i.e. the ability to serve multiple requests simultaneously.
#
# Notes:
#
# This option is only there for debugging purposes. It will
# drastically reduce performance.
#
#single-threaded
#
#
# 3.3. hostname
# ==============
#
# Specifies:
#
# The hostname shown on the CGI pages.
#
# Type of value:
#
# Text
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# The hostname provided by the operating system is used.
#
# Notes:
#
# On some misconfigured systems resolving the hostname fails or
# takes too much time and slows Privoxy down. Setting a fixed
# hostname works around the problem.
#
# In other circumstances it might be desirable to show a hostname
# other than the one returned by the operating system. For example
# if the system has several different hostnames and you don't
# want to use the first one.
#
# Note that Privoxy does not validate the specified hostname value.
#
#hostname hostname.example.org
#
#
# 4. ACCESS CONTROL AND SECURITY
# ===============================
#
# This section of the config file controls the security-relevant
# aspects of Privoxy's configuration.
#
#
#
# 4.1. listen-address
# ====================
#
# Specifies:
#
# The address and TCP port on which Privoxy will listen for
# client requests.
#
# Type of value:
#
# [IP-Address]:Port
#
# [Hostname]:Port
#
# Default value:
#
# 127.0.0.1:8118
#
# Effect if unset:
#
# Bind to 127.0.0.1 (IPv4 localhost), port 8118. This is suitable
# and recommended for home users who run Privoxy on the same
# machine as their browser.
#
# Notes:
#
# You will need to configure your browser(s) to this proxy address
# and port.
#
# If you already have another service running on port 8118, or
# if you want to serve requests from other machines (e.g. on your
# local network) as well, you will need to override the default.
#
# You can use this statement multiple times to make Privoxy listen
# on more ports or more IP addresses. Suitable if your operating
# system does not support sharing IPv6 and IPv4 protocols on the
# same socket.
#
# If a hostname is used instead of an IP address, Privoxy will
# try to resolve it to an IP address and if there are multiple,
# use the first one returned.
#
# If the address for the hostname isn't already known on the
# system (for example because it's in /etc/hostname), this may
# result in DNS traffic.
#
# If the specified address isn't available on the system, or if
# the hostname can't be resolved, Privoxy will fail to start.
#
# IPv6 addresses containing colons have to be quoted by
# brackets. They can only be used if Privoxy has been compiled
# with IPv6 support. If you aren't sure if your version supports
# it, have a look at http://config.privoxy.org/ show-status.
#
# Some operating systems will prefer IPv6 to IPv4 addresses even if
# the system has no IPv6 connectivity which is usually not expected
# by the user. Some even rely on DNS to resolve localhost which
# mean the "localhost" address used may not actually be local.
#
# It is therefore recommended to explicitly configure the intended
# IP address instead of relying on the operating system, unless
# there's a strong reason not to.
#
# If you leave out the address, Privoxy will bind to all IPv4
# interfaces (addresses) on your machine and may become reachable
# from the Internet and/ or the local network. Be aware that
# some GNU/Linux distributions modify that behaviour without
# updating the documentation. Check for non-standard patches if
# your Privoxyversion behaves differently.
#
# If you configure Privoxyto be reachable from the network,
# consider using access control lists (ACL's, see below), and/or
# a firewall.
#
# If you open Privoxy to untrusted users, you will also
# want to make sure that the following actions are disabled:
# enable-edit-actions and enable-remote-toggle
#
# With the exception noted above, listening on multiple addresses
# is currently not supported by Privoxy directly. It can be done
# on most operating systems by letting a packet filter redirect
# request for certain addresses to Privoxy, though.
#
# Example:
#
# Suppose you are running Privoxy on a machine which has the
# address 192.168.0.1 on your local private network (192.168.0.0)
# and has another outside connection with a different address. You
# want it to serve requests from inside only:
#
# listen-address 192.168.0.1:8118
#
# Suppose you are running Privoxy on an IPv6-capable machine and
# you want it to listen on the IPv6 address of the loopback device:
#
# listen-address [::1]:8118
#
listen-address 0.0.0.0:8118
#
#
# 4.2. toggle
# ============
#
# Specifies:
#
# Initial state of "toggle" status
#
# Type of value:
#
# 1 or 0
#
# Default value:
#
# 1
#
# Effect if unset:
#
# Act as if toggled on
#
# Notes:
#
# If set to 0, Privoxy will start in "toggled off" mode,
# i.e. mostly behave like a normal, content-neutral proxy
# with both ad blocking and content filtering disabled. See
# enable-remote-toggle below.
#
# The windows version will only display the toggle icon in the
# system tray if this option is present.
#
toggle 1
#
#
# 4.3. enable-remote-toggle
# ==========================
#
# Specifies:
#
# Whether or not the web-based toggle feature may be used
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# The web-based toggle feature is disabled.
#
# Notes:
#
# When toggled off, Privoxy mostly acts like a normal,
# content-neutral proxy, i.e. doesn't block ads or filter content.
#
# Access to the toggle feature can not be controlled separately by
# "ACLs" or HTTP authentication, so that everybody who can access
# Privoxy (see "ACLs" and listen-address above) can toggle it
# for all users. So this option is not recommended for multi-user
# environments with untrusted users.
#
# Note that malicious client side code (e.g Java) is also capable
# of using this option.
#
# As a lot of Privoxy users don't read documentation, this feature
# is disabled by default.
#
# Note that you must have compiled Privoxy with support for this
# feature, otherwise this option has no effect.
#
enable-remote-toggle 0
#
#
# 4.4. enable-remote-http-toggle
# ===============================
#
# Specifies:
#
# Whether or not Privoxy recognizes special HTTP headers to change
# its behaviour.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Privoxy ignores special HTTP headers.
#
# Notes:
#
# When toggled on, the client can change Privoxy's behaviour by
# setting special HTTP headers. Currently the only supported
# special header is "X-Filter: No", to disable filtering for
# the ongoing request, even if it is enabled in one of the
# action files.
#
# This feature is disabled by default. If you are using Privoxy in
# a environment with trusted clients, you may enable this feature
# at your discretion. Note that malicious client side code (e.g
# Java) is also capable of using this feature.
#
# This option will be removed in future releases as it has been
# obsoleted by the more general header taggers.
#
enable-remote-http-toggle 0
#
#
# 4.5. enable-edit-actions
# =========================
#
# Specifies:
#
# Whether or not the web-based actions file editor may be used
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# The web-based actions file editor is disabled.
#
# Notes:
#
# Access to the editor can not be controlled separately by
# "ACLs" or HTTP authentication, so that everybody who can access
# Privoxy (see "ACLs" and listen-address above) can modify its
# configuration for all users.
#
# This option is not recommended for environments with untrusted
# users and as a lot of Privoxy users don't read documentation,
# this feature is disabled by default.
#
# Note that malicious client side code (e.g Java) is also capable
# of using the actions editor and you shouldn't enable this
# options unless you understand the consequences and are sure
# your browser is configured correctly.
#
# Note that you must have compiled Privoxy with support for this
# feature, otherwise this option has no effect.
#
enable-edit-actions 0
#
#
# 4.6. enforce-blocks
# ====================
#
# Specifies:
#
# Whether the user is allowed to ignore blocks and can "go there
# anyway".
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Blocks are not enforced.
#
# Notes:
#
# Privoxy is mainly used to block and filter requests as a service
# to the user, for example to block ads and other junk that clogs
# the pipes. Privoxy's configuration isn't perfect and sometimes
# innocent pages are blocked. In this situation it makes sense to
# allow the user to enforce the request and have Privoxy ignore
# the block.
#
# In the default configuration Privoxy's "Blocked" page contains
# a "go there anyway" link to adds a special string (the force
# prefix) to the request URL. If that link is used, Privoxy
# will detect the force prefix, remove it again and let the
# request pass.
#
# Of course Privoxy can also be used to enforce a network
# policy. In that case the user obviously should not be able to
# bypass any blocks, and that's what the "enforce-blocks" option
# is for. If it's enabled, Privoxy hides the "go there anyway"
# link. If the user adds the force prefix by hand, it will not
# be accepted and the circumvention attempt is logged.
#
# Examples:
#
# enforce-blocks 1
#
enforce-blocks 0
#
#
# 4.7. ACLs: permit-access and deny-access
# =========================================
#
# Specifies:
#
# Who can access what.
#
# Type of value:
#
# src_addr[:port][/src_masklen] [dst_addr[:port][/dst_masklen]]
#
# Where src_addr and dst_addr are IPv4 addresses in dotted
# decimal notation or valid DNS names, port is a port number, and
# src_masklen and dst_masklen are subnet masks in CIDR notation,
# i.e. integer values from 2 to 30 representing the length
# (in bits) of the network address. The masks and the whole
# destination part are optional.
#
# If your system implements RFC 3493, then src_addr and dst_addr
# can be IPv6 addresses delimeted by brackets, port can be a
# number or a service name, and src_masklen and dst_masklen can
# be a number from 0 to 128.
#
# Default value:
#
# Unset
#
# If no port is specified, any port will match. If no src_masklen
# or src_masklen is given, the complete IP address has to match
# (i.e. 32 bits for IPv4 and 128 bits for IPv6).
#
# Effect if unset:
#
# Don't restrict access further than implied by listen-address
#
# Notes:
#
# Access controls are included at the request of ISPs and systems
# administrators, and are not usually needed by individual
# users. For a typical home user, it will normally suffice to
# ensure that Privoxy only listens on the localhost (127.0.0.1)
# or internal (home) network address by means of the listen-address
# option.
#
# Please see the warnings in the FAQ that Privoxy is not intended
# to be a substitute for a firewall or to encourage anyone to
# defer addressing basic security weaknesses.
#
# Multiple ACL lines are OK. If any ACLs are specified, Privoxy
# only talks to IP addresses that match at least one permit-access
# line and don't match any subsequent deny-access line. In other
# words, the last match wins, with the default being deny-access.
#
# If Privoxy is using a forwarder (see forward below) for a
# particular destination URL, the dst_addr that is examined is
# the address of the forwarder and NOT the address of the ultimate
# target. This is necessary because it may be impossible for the
# local Privoxy to determine the IP address of the ultimate target
# (that's often what gateways are used for).
#
# You should prefer using IP addresses over DNS names, because
# the address lookups take time. All DNS names must resolve! You
# can not use domain patterns like "*.org" or partial domain
# names. If a DNS name resolves to multiple IP addresses, only
# the first one is used.
#
# Some systems allow IPv4 clients to connect to IPv6 server
# sockets. Then the client's IPv4 address will be translated by the
# system into IPv6 address space with special prefix ::ffff:0:0/96
# (so called IPv4 mapped IPv6 address). Privoxy can handle it
# and maps such ACL addresses automatically.
#
# Denying access to particular sites by ACL may have undesired
# side effects if the site in question is hosted on a machine
# which also hosts other sites (most sites are).
#
# Examples:
#
# Explicitly define the default behavior if no ACL and
# listen-address are set: "localhost" is OK. The absence of a
# dst_addr implies that all destination addresses are OK:
#
# permit-access localhost
#
#
# Allow any host on the same class C subnet as www.privoxy.org
# access to nothing but www.example.com (or other domains hosted
# on the same system):
#
# permit-access www.privoxy.org/24 www.example.com/32
#
#
# Allow access from any host on the 26-bit subnet 192.168.45.64 to
# anywhere, with the exception that 192.168.45.73 may not access
# the IP address behind www.dirty-stuff.example.com:
#
# permit-access 192.168.45.64/26
# deny-access 192.168.45.73 www.dirty-stuff.example.com
#
# Allow access from the IPv4 network 192.0.2.0/24 even if listening
# on an IPv6 wild card address (not supported on all platforms):
#
# permit-access 192.0.2.0/24
#
#
# This is equivalent to the following line even if listening on
# an IPv4 address (not supported on all platforms):
#
# permit-access [::ffff:192.0.2.0]/120
#
#
# 4.8. buffer-limit
# ==================
#
# Specifies:
#
# Maximum size of the buffer for content filtering.
#
# Type of value:
#
# Size in Kbytes
#
# Default value:
#
# 4096
#
# Effect if unset:
#
# Use a 4MB (4096 KB) limit.
#
# Notes:
#
# For content filtering, i.e. the +filter and +deanimate-gif
# actions, it is necessary that Privoxy buffers the entire document
# body. This can be potentially dangerous, since a server could
# just keep sending data indefinitely and wait for your RAM to
# exhaust -- with nasty consequences. Hence this option.
#
# When a document buffer size reaches the buffer-limit, it is
# flushed to the client unfiltered and no further attempt to filter
# the rest of the document is made. Remember that there may be
# multiple threads running, which might require up to buffer-limit
# Kbytes each, unless you have enabled "single-threaded" above.
#
buffer-limit 4096
#
#
# 5. FORWARDING
# ==============
#
# This feature allows routing of HTTP requests through a chain of
# multiple proxies.
#
# Forwarding can be used to chain Privoxy with a caching proxy to
# speed up browsing. Using a parent proxy may also be necessary if
# the machine that Privoxy runs on has no direct Internet access.
#
# Note that parent proxies can severely decrease your privacy
# level. For example a parent proxy could add your IP address to the
# request headers and if it's a caching proxy it may add the "Etag"
# header to revalidation requests again, even though you configured
# Privoxy to remove it. It may also ignore Privoxy's header time
# randomization and use the original values which could be used by
# the server as cookie replacement to track your steps between visits.
#
# Also specified here are SOCKS proxies. Privoxy supports the SOCKS
# 4 and SOCKS 4A protocols.
#
#
#
# 5.1. forward
# =============
#
# Specifies:
#
# To which parent HTTP proxy specific requests should be routed.
#
# Type of value:
#
# target_pattern http_parent[:port]
#
# where target_pattern is a URL pattern that specifies to which
# requests (i.e. URLs) this forward rule shall apply. Use /
# to denote "all URLs". http_parent[:port] is the DNS name or
# IP address of the parent HTTP proxy through which the requests
# should be forwarded, optionally followed by its listening port
# (default: 8000). Use a single dot (.) to denote "no forwarding".
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# Don't use parent HTTP proxies.
#
# Notes:
#
# If http_parent is ".", then requests are not forwarded to
# another HTTP proxy but are made directly to the web servers.
#
# http_parent can be a numerical IPv6 address (if RFC 3493 is
# implemented). To prevent clashes with the port delimiter,
# the whole IP address has to be put into brackets. On the other
# hand a target_pattern containing an IPv6 address has to be put
# into angle brackets (normal brackets are reserved for regular
# expressions already).
#
# Multiple lines are OK, they are checked in sequence, and the
# last match wins.
#
# Examples:
#
# Everything goes to an example parent proxy, except SSL on port
# 443 (which it doesn't handle):
#
# forward / parent-proxy.example.org:8080
# forward :443 .
#
#
# Everything goes to our example ISP's caching proxy, except for
# requests to that ISP's sites:
#
# forward / caching-proxy.isp.example.net:8000
# forward .isp.example.net .
#
#
# Parent proxy specified by an IPv6 address:
#
# forward / [2001:DB8::1]:8000
#
#
# Suppose your parent proxy doesn't support IPv6:
#
# forward / parent-proxy.example.org:8000
# forward ipv6-server.example.org .
# forward <[2-3][0-9a-f][0-9a-f][0-9a-f]:*> .
#
#
# 5.2. forward-socks4, forward-socks4a and forward-socks5
# ========================================================
#
# Specifies:
#
# Through which SOCKS proxy (and optionally to which parent HTTP
# proxy) specific requests should be routed.
#
# Type of value:
#
# target_pattern socks_proxy[:port] http_parent[:port]
#
# where target_pattern is a URL pattern that specifies to which
# requests (i.e. URLs) this forward rule shall apply. Use / to
# denote "all URLs". http_parent and socks_proxy are IP addresses
# in dotted decimal notation or valid DNS names (http_parent may
# be "." to denote "no HTTP forwarding"), and the optional port
# parameters are TCP ports, i.e. integer values from 1 to 65535
#
# Default value:
#
# Unset
#
# Effect if unset:
#
# Don't use SOCKS proxies.
#
# Notes:
#
# Multiple lines are OK, they are checked in sequence, and the
# last match wins.
#
# The difference between forward-socks4 and forward-socks4a
# is that in the SOCKS 4A protocol, the DNS resolution of the
# target hostname happens on the SOCKS server, while in SOCKS 4
# it happens locally.
#
# With forward-socks5 the DNS resolution will happen on the remote
# server as well.
#
# socks_proxy and http_parent can be a numerical IPv6 address
# (if RFC 3493 is implemented). To prevent clashes with the port
# delimiter, the whole IP address has to be put into brackets. On
# the other hand a target_pattern containing an IPv6 address has
# to be put into angle brackets (normal brackets are reserved
# for regular expressions already).
#
# If http_parent is ".", then requests are not forwarded to another
# HTTP proxy but are made (HTTP-wise) directly to the web servers,
# albeit through a SOCKS proxy.
#
# Examples:
#
# From the company example.com, direct connections are made to all
# "internal" domains, but everything outbound goes through their
# ISP's proxy by way of example.com's corporate SOCKS 4A gateway
# to the Internet.
#
# forward-socks4a / socks-gw.example.com:1080 www-cache.isp.example.net:8080
# forward .example.com .
#
#
# A rule that uses a SOCKS 4 gateway for all destinations but no
# HTTP parent looks like this:
#
# forward-socks4 / socks-gw.example.com:1080 .
#
#
# To chain Privoxy and Tor, both running on the same system,
# you would use something like:
#
# forward-socks5 / 127.0.0.1:9050 .
#
#
# The public Tor network can't be used to reach your local network,
# if you need to access local servers you therefore might want
# to make some exceptions:
#
# forward 192.168.*.*/ .
# forward 10.*.*.*/ .
# forward 127.*.*.*/ .
#
#
# Unencrypted connections to systems in these address ranges will
# be as (un) secure as the local network is, but the alternative
# is that you can't reach the local network through Privoxy at
# all. Of course this may actually be desired and there is no
# reason to make these exceptions if you aren't sure you need them.
#
# If you also want to be able to reach servers in your local
# network by using their names, you will need additional exceptions
# that look like this:
#
# forward localhost/ .
#
#
forward-socks5 / torproxy:9050 .
#
# 5.3. forwarded-connect-retries
# ===============================
#
# Specifies:
#
# How often Privoxy retries if a forwarded connection request
# fails.
#
# Type of value:
#
# Number of retries.
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Connections forwarded through other proxies are treated like
# direct connections and no retry attempts are made.
#
# Notes:
#
# forwarded-connect-retries is mainly interesting for socks4a
# connections, where Privoxy can't detect why the connections
# failed. The connection might have failed because of a DNS timeout
# in which case a retry makes sense, but it might also have failed
# because the server doesn't exist or isn't reachable. In this
# case the retry will just delay the appearance of Privoxy's
# error message.
#
# Note that in the context of this option, "forwarded connections"
# includes all connections that Privoxy forwards through other
# proxies. This option is not limited to the HTTP CONNECT method.
#
# Only use this option, if you are getting lots of
# forwarding-related error messages that go away when you try again
# manually. Start with a small value and check Privoxy's logfile
# from time to time, to see how many retries are usually needed.
#
# Due to a bug, this option currently also causes Privoxy to
# retry in case of certain problems with direct connections.
#
# Examples:
#
# forwarded-connect-retries 1
#
forwarded-connect-retries 0
#
#
# 6. MISCELLANEOUS
# =================
#
# 6.1. accept-intercepted-requests
# =================================
#
# Specifies:
#
# Whether intercepted requests should be treated as valid.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Only proxy requests are accepted, intercepted requests are
# treated as invalid.
#
# Notes:
#
# If you don't trust your clients and want to force them to use
# Privoxy, enable this option and configure your packet filter
# to redirect outgoing HTTP connections into Privoxy.
#
# Make sure that Privoxy's own requests aren't redirected as well.
# Additionally take care that Privoxy can't intentionally connect
# to itself, otherwise you could run into redirection loops if
# Privoxy's listening port is reachable by the outside or an
# attacker has access to the pages you visit.
#
# Examples:
#
# accept-intercepted-requests 1
#
accept-intercepted-requests 0
#
#
# 6.2. allow-cgi-request-crunching
# =================================
#
# Specifies:
#
# Whether requests to Privoxy's CGI pages can be blocked or
# redirected.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Privoxy ignores block and redirect actions for its CGI pages.
#
# Notes:
#
# By default Privoxy ignores block or redirect actions for
# its CGI pages. Intercepting these requests can be useful in
# multi-user setups to implement fine-grained access control,
# but it can also render the complete web interface useless and
# make debugging problems painful if done without care.
#
# Don't enable this option unless you're sure that you really
# need it.
#
# Examples:
#
# allow-cgi-request-crunching 1
#
allow-cgi-request-crunching 0
#
#
# 6.3. split-large-forms
# =======================
#
# Specifies:
#
# Whether the CGI interface should stay compatible with broken
# HTTP clients.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# The CGI form generate long GET URLs.
#
# Notes:
#
# Privoxy's CGI forms can lead to rather long URLs. This isn't
# a problem as far as the HTTP standard is concerned, but it can
# confuse clients with arbitrary URL length limitations.
#
# Enabling split-large-forms causes Privoxy to divide big forms
# into smaller ones to keep the URL length down. It makes editing
# a lot less convenient and you can no longer submit all changes
# at once, but at least it works around this browser bug.
#
# If you don't notice any editing problems, there is no reason
# to enable this option, but if one of the submit buttons appears
# to be broken, you should give it a try.
#
# Examples:
#
# split-large-forms 1
#
split-large-forms 0
#
#
# 6.4. keep-alive-timeout
# ========================
#
# Specifies:
#
# Number of seconds after which an open connection will no longer
# be reused.
#
# Type of value:
#
# Time in seconds.
#
# Default value:
#
# None
#
# Effect if unset:
#
# Connections are not kept alive.
#
# Notes:
#
# This option allows clients to keep the connection to Privoxy
# alive. If the server supports it, Privoxy will keep the
# connection to the server alive as well. Under certain
# circumstances this may result in speed-ups.
#
# By default, Privoxy will close the connection to the server if
# the client connection gets closed, or if the specified timeout
# has been reached without a new request coming in. This behaviour
# can be changed with the connection-sharing option.
#
# This option has no effect if Privoxy has been compiled without
# keep-alive support.
#
# Note that a timeout of five seconds as used in the default
# configuration file significantly decreases the number of
# connections that will be reused. The value is used because some
# browsers limit the number of connections they open to a single
# host and apply the same limit to proxies. This can result in a
# single website "grabbing" all the connections the browser allows,
# which means connections to other websites can't be opened until
# the connections currently in use time out.
#
# Several users have reported this as a Privoxy bug, so the default
# value has been reduced. Consider increasing it to 300 seconds
# or even more if you think your browser can handle it. If your
# browser appears to be hanging it can't.
#
# Examples:
#
# keep-alive-timeout 300
#
keep-alive-timeout 5
#
#
# 6.5. default-server-timeout
# ============================
#
# Specifies:
#
# Assumed server-side keep-alive timeout if not specified by
# the server.
#
# Type of value:
#
# Time in seconds.
#
# Default value:
#
# None
#
# Effect if unset:
#
# Connections for which the server didn't specify the keep-alive
# timeout are not reused.
#
# Notes:
#
# Enabling this option significantly increases the number of
# connections that are reused, provided the keep-alive-timeout
# option is also enabled.
#
# While it also increases the number of connections problems when
# Privoxy tries to reuse a connection that already has been closed
# on the server side, or is closed while Privoxy is trying to
# reuse it, this should only be a problem if it happens for the
# first request sent by the client. If it happens for requests
# on reused client connections, Privoxy will simply close the
# connection and the client is supposed to retry the request
# without bothering the user.
#
# Enabling this option is therefore only recommended if the
# connection-sharing option is disabled.
#
# It is an error to specify a value larger than the
# keep-alive-timeout value.
#
# This option has no effect if Privoxy has been compiled without
# keep-alive support.
#
# Examples:
#
# default-server-timeout 60
#
#default-server-timeout 60
#
#
# 6.6. connection-sharing
# ========================
#
# Specifies:
#
# Whether or not outgoing connections that have been kept alive
# should be shared between different incoming connections.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# None
#
# Effect if unset:
#
# Connections are not shared.
#
# Notes:
#
# This option has no effect if Privoxy has been compiled without
# keep-alive support, or if it's disabled.
#
# Notes:
#
# Note that reusing connections doesn't necessary cause
# speedups. There are also a few privacy implications you should
# be aware of.
#
# If this option is effective, outgoing connections are shared
# between clients (if there are more than one) and closing the
# browser that initiated the outgoing connection does no longer
# affect the connection between Privoxy and the server unless
# the client's request hasn't been completed yet.
#
# If the outgoing connection is idle, it will not be closed until
# either Privoxy's or the server's timeout is reached. While
# it's open, the server knows that the system running Privoxy is
# still there.
#
# If there are more than one client (maybe even belonging to
# multiple users), they will be able to reuse each others
# connections. This is potentially dangerous in case of
# authentication schemes like NTLM where only the connection
# is authenticated, instead of requiring authentication for
# each request.
#
# If there is only a single client, and if said client can keep
# connections alive on its own, enabling this option has next to
# no effect. If the client doesn't support connection keep-alive,
# enabling this option may make sense as it allows Privoxy to keep
# outgoing connections alive even if the client itself doesn't
# support it.
#
# You should also be aware that enabling this option increases
# the likelihood of getting the "No server or forwarder data"
# error message, especially if you are using a slow connection
# to the Internet.
#
# This option should only be used by experienced users who
# understand the risks and can weight them against the benefits.
#
# Examples:
#
# connection-sharing 1
#
#connection-sharing 1
#
#
# 6.7. socket-timeout
# ====================
#
# Specifies:
#
# Number of seconds after which a socket times out if no data
# is received.
#
# Type of value:
#
# Time in seconds.
#
# Default value:
#
# None
#
# Effect if unset:
#
# A default value of 300 seconds is used.
#
# Notes:
#
# For SOCKS requests the timeout currently doesn't start until
# the SOCKS server accepted the request. This will be fixed in
# the next release.
#
# Examples:
#
# socket-timeout 300
#
socket-timeout 300
#
#
# 6.8. max-client-connections
# ============================
#
# Specifies:
#
# Maximum number of client connections that will be served.
#
# Type of value:
#
# Positive number.
#
# Default value:
#
# None
#
# Effect if unset:
#
# Connections are served until a resource limit is reached.
#
# Notes:
#
# Privoxy creates one thread (or process) for every incoming
# client connection that isn't rejected based on the access
# control settings.
#
# If the system is powerful enough, Privoxy can theoretically deal
# with several hundred (or thousand) connections at the same time,
# but some operating systems enforce resource limits by shutting
# down offending processes and their default limits may be below
# the ones Privoxy would require under heavy load.
#
# Configuring Privoxy to enforce a connection limit below the
# thread or process limit used by the operating system makes
# sure this doesn't happen. Simply increasing the operating
# system's limit would work too, but if Privoxy isn't the only
# application running on the system, you may actually want to
# limit the resources used by Privoxy.
#
# If Privoxy is only used by a single trusted user, limiting the
# number of client connections is probably unnecessary. If there
# are multiple possibly untrusted users you probably still want
# to additionally use a packet filter to limit the maximal number
# of incoming connections per client. Otherwise a malicious user
# could intentionally create a high number of connections to
# prevent other users from using Privoxy.
#
# Obviously using this option only makes sense if you choose a
# limit below the one enforced by the operating system.
#
# Examples:
#
# max-client-connections 256
#
#max-client-connections 256
#
# 6.9. handle-as-empty-doc-returns-ok
# ====================================
#
# Specifies:
#
# The status code Privoxy returns for pages blocked with
# +handle-as-empty-document.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Privoxy returns a status 403(forbidden) for all blocked pages.
#
# Effect if set:
#
# Privoxy returns a status 200(OK) for pages blocked with
# +handle-as-empty-document and a status 403(Forbidden) for all
# other blocked pages.
#
# Notes:
#
# This is a work-around for Firefox bug 492459: " Websites are no
# longer rendered if SSL requests for JavaScripts are blocked by a
# proxy. " (https:/ /bugzilla.mozilla.org/show_bug.cgi?id=492459)
# As the bug has been fixed for quite some time this option
# should no longer be needed and will be removed in a future
# release. Please speak up if you have a reason why the option
# should be kept around.
#
#handle-as-empty-doc-returns-ok 1
#
#
# 1.6.10. enable-compression
#
# Specifies:
#
# Whether or not buffered content is compressed before delivery.
#
# Type of value:
#
# 0 or 1
#
# Default value:
#
# 0
#
# Effect if unset:
#
# Privoxy does not compress buffered content.
#
# Effect if set:
#
# Privoxy compresses buffered content before delivering it to
# the client, provided the client supports it.
#
# Notes:
#
# This directive is only supported if Privoxy has been compiled
# with FEATURE_COMPRESSION, which should not to be confused
# with FEATURE_ZLIB.
#
# Compressing buffered content is mainly useful if Privoxy and the
# client are running on different systems. If they are running on
# the same system, enabling compression is likely to slow things
# down. If you didn't measure otherwise, you should assume that
# it does and keep this option disabled.
#
# Privoxy will not compress buffered content below a certain
# length.
#
#enable-compression 1
#
#
# 1.6.11. compression-level
#
# Specifies:
#
# The compression level that is passed to the zlib library when
# compressing buffered content.
#
# Type of value:
#
# Positive number ranging from 0 to 9.
#
# Default value:
#
# 1

# Notes:
#
# Compressing the data more takes usually longer than compressing
# it less or not compressing it at all. Which level is best
# depends on the connection between Privoxy and the client. If
# you can't be bothered to benchmark it for yourself, you should
# stick with the default and keep compression disabled.
#
# If compression is disabled, the compression level is irrelevant.
#
# Examples:
#
# # Best speed (compared to the other levels)
# compression-level 1
#
# # Best compression
# compression-level 9
#
# # No compression. Only useful for testing as the added header
# # slightly increases the amount of data that has to be sent.
# # If your benchmark shows that using this compression level
# # is superior to using no compression at all, the benchmark
# # is likely to be flawed.
# compression-level 0
#
#
#compression-level 1

# 7. WINDOWS GUI OPTIONS
# =======================
#
# Privoxy has a number of options specific to the Windows GUI
# interface:
#
#
# If "activity-animation" is set to 1, the Privoxy icon will animate
# when "Privoxy" is active. To turn off, set to 0.
#
#activity-animation 1
#
# If "log-messages" is set to 1, Privoxy will log messages to the
# console window:
#
#log-messages 1
#
# If "log-buffer-size" is set to 1, the size of the log buffer,
# i.e. the amount of memory used for the log messages displayed in
# the console window, will be limited to "log-max-lines" (see below).
#
# Warning: Setting this to 0 will result in the buffer to grow
# infinitely and eat up all your memory!
#
#log-buffer-size 1
#
# log-max-lines is the maximum number of lines held in the log
# buffer. See above.
#
#log-max-lines 200
#
# If "log-highlight-messages" is set to 1, Privoxy will highlight
# portions of the log messages with a bold-faced font:
#
#log-highlight-messages 1
#
# The font used in the console window:
#
#log-font-name Comic Sans MS
#
# Font size used in the console window:
#
#log-font-size 8
#
# "show-on-task-bar" controls whether or not Privoxy will appear as
# a button on the Task bar when minimized:
#
#show-on-task-bar 0
#
# If "close-button-minimizes" is set to 1, the Windows close button
# will minimize Privoxy instead of closing the program (close with
# the exit option on the File menu).
#
#close-button-minimizes 1
#
# The "hide-console" option is specific to the MS-Win console version
# of Privoxy. If this option is used, Privoxy will disconnect from
# and hide the command console.
#
#hide-console
