If you modify this -# file, you will need to stop & restart Junkbuster, or use the -# "Reload Config" option (Windows) before any changes take effect. +# I. INTRODUCTION +# =============== # -# When starting Junkbuster on Unix systems, give the name of this -# file as an argument. On Windows systems, Junkbuster will look for -# this file with the name 'junkbustr.txt' in the same directory where -# Junkbuster is installed. +# 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. # -# 2. FORMAT OF THE 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. # -# 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, +# 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. # -# blockfile blocklist.ini # -# Indicates that the blockfile is named 'blocklist.ini'. +# II. FORMAT OF THE CONFIGURATION FILE +# ==================================== # -# The '#' indicates a comment. Any part of a line following a '#' is +# 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 to turn -# off features: If you comment out the "logfile" line, junkbuster will -# not log to a file at all. Watch for the "default:" section in each -# explanation to see what happens if the option is left unset (or -# commented out). -# -# Long lines can be continued on the next line by using a `\' as -# the last character. -# - -# -# 3. OTHER CONFIGURATION FILES -# -# Junkbuster uses a number of other files to tell it what ads to -# block, what cookies to accept, etc. This section of the -# configuration file tells Junkbuster where to find all those other -# files. -# -# On Windows, Junkbuster looks for these files in the same -# directory as the executable. On Unix, Junkbuster looks for these -# files in the current working directory. In either case, an -# absolute path name can be used to avoid problems. - -# While we go modular and multiuser, the blocker, filter, and -# per-user config will be stored in subdirectories of confdir. -# Now, only confdir/templates is used for storing HTML templates -# for CGI results. -# -# No trailing /, please. +# 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: +# +# https://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 https://www.privoxy.org/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.

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 . - # -# The directory where all logging (i.e. logfile and jarfile) takes place -# No trailing /, please. +# 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. temporary-directory +# ========================= +# +# Specifies: +# +# A directory where Privoxy can create temporary files. +# +# Type of value: +# +# Path name +# +# Default value: +# +# unset +# +# Effect if unset: +# +# No temporary files are created, external filters don't work. +# +# Notes: +# +# To execute external filters, Privoxy has to create temporary +# files.

You can also mark -# sites as trusted referrers, with the effect that access to -# untrusted sites will be granted, if a link from a trusted -# referrer was used. The link target will then be added to the -# trustfile. -# Note that this is a very restrictive feature that typical users -# most propably want to leave disabled. +# No textual content filtering takes place, i.e. all +filter{name} +# actions in the actions files are turned neutral. # -# Default: Don't use the trust mechanism +# 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.

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 only logs fatal errors by +# default. +# +# For most troubleshooting purposes, you will have to change +# that, please refer to the debugging section for details. +# +# Any log files must be writable by whatever user Privoxy is +# being run as (on Unix, default user id is "privoxy"). +# +# To prevent the logfile from growing indefinitely, it is +# recommended to periodically rotate or shorten it. Many +# operating systems support log rotation out of the box, some +# require additional software to do it. For details, please +# refer to the documentation for your operating system. +# +logfile logfile +# +# 2.8. 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 - # -# If you use the trust mechanism, it is a good idea to write up -# some online documentation about your blocking policy and to -# specify the URL(s) here.

DEBUGGING +# ============= # -# Default: Don't display links on the "untrusted" info page. +# These options are mainly useful when tracing a problem.

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 +# +# 6.8. 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: +# +# The default is quite high and you probably want to reduce it. +# If you aren't using an occasionally slow proxy like Tor, +# reducing it to a few seconds should be fine. +# +# Examples: +# +# socket-timeout 300 +# +socket-timeout 300 +# +# 6.9. max-client-connections +# ============================ +# +# Specifies: +# +# Maximum number of client connections that will be served. +# +# Type of value: +# +# Positive number. +# +# Default value: +# +# 128 +# +# 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.

It is recommended that ACL are used to +# make sure only trusted systems can reach Privoxy. +# +# If access to Privoxy isn't limited to trusted systems, this +# option would allow malicious clients to change the client tags +# for other clients or increase Privoxy's memory requirements by +# registering lots of client tag settings for clients that don't +# exist. +# +# Examples: +# +# # Allow systems that can reach Privoxy to provide the client +# # IP address with a X-Forwarded-For header. +# trust-x-forwarded-for 1 +# +# +# +# 6.19. receive-buffer-size +# ========================== +# +# Specifies: +# +# The size of the buffer Privoxy uses to receive data from the +# server. +# +# Type of value: +# +# Size in bytes +# +# Default value: +# +# 5000 +# +# Notes: +# +# Increasing the receive-buffer-size increases Privoxy's memory +# usage but can lower the number of context switches and thereby +# reduce the cpu usage and potentially increase the throughput. +# +# This is mostly relevant for fast network connections and large +# downloads that don't require filtering. +# +# Reducing the buffer size reduces the amount of memory Privoxy +# needs to handle the request but increases the number of +# systemcalls and may reduce the throughput. +# +# A dtrace command like: "sudo dtrace -n 'syscall::read:return / +# execname == "privoxy"/ { @[execname] = llquantize(arg0, 10, 0, +# 5, 20); @m = max(arg0)}'" can be used to properly tune the +# receive-buffer-size. On systems without dtrace, strace or +# truss may be used as less convenient alternatives. +# +# If the buffer is too large it will increase Privoxy's memory +# footprint without any benefit. As the memory is (currently) +# cleared before using it, a buffer that is too large can +# actually reduce the throughput. +# +# Examples: +# +# # Increase the receive buffer size +# receive-buffer-size 32768 +# +# +# +# 7.
