- #
- # 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").
- #
- # 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
- # debug 65536 # Log the applying actions
- #
- # 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. See also debug 1024.
- #debug 1024 # Actions that are applied to all sites and maybe overruled later on.
- #debug 4096 # Startup banner and warnings
- #debug 8192 # 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 Privoxy version behaves differently.
- #
- # If you configure Privoxy to 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
- #
- # 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 localhost: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.
- #
- 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
- #
- # 4.9. enable-proxy-authentication-forwarding
- # ============================================
- #
- # Specifies:
- #
- # Whether or not proxy authentication through Privoxy should
- # work.
- #
- # Type of value:
- #
- # 0 or 1
- #
- # Default value:
- #
- # 0
- #
- # Effect if unset:
- #
- # Proxy authentication headers are removed.
- #
- # Notes:
- #
- # Privoxy itself does not support proxy authentication, but can
- # allow clients to authenticate against Privoxy's parent proxy.
- #
- # By default Privoxy (3.0.21 and later) don't do that and remove
- # Proxy-Authorization headers in requests and Proxy-Authenticate
- # headers in responses to make it harder for malicious sites to
- # trick inexperienced users into providing login information.
- #
- # If this option is enabled the headers are forwarded.
- #
- # Enabling this option is not recommended if there is no parent
- # proxy that requires authentication or if the local network
- # between Privoxy and the parent proxy isn't trustworthy. If
- # proxy authentication is only required for some requests, it is
- # recommended to use a client header filter to remove the
- # authentication headers for requests where they aren't needed.
- #
- enable-proxy-authentication-forwarding 0
- #
- # 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, forward-socks5 and forward-socks5t
- # =========================================================================
- #
- # 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.
- #
- # forward-socks5t works like vanilla forward-socks5 but lets
- # Privoxy additionally use Tor-specific SOCKS extensions.
- # Currently the only supported SOCKS extension is optimistic
- # data which can reduce the latency for the first request made
- # on a newly created connection.
- #
- # 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/ .
- #
- #
- # 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.
- #
- # 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 probably can't.
- #
- # Examples:
- #
- # keep-alive-timeout 300
- #
- keep-alive-timeout 5
- #
- # 6.5. tolerate-pipelining
- # =========================
- #
- # Specifies:
- #
- # Whether or not pipelined requests should be served.
- #
- # Type of value:
- #
- # 0 or 1.
- #
- # Default value:
- #
- # None
- #
- # Effect if unset:
- #
- # If Privoxy receives more than one request at once, it
- # terminates the client connection after serving the first one.
- #
- # Notes:
- #
- # Privoxy currently doesn't pipeline outgoing requests, thus
- # allowing pipelining on the client connection is not guaranteed
- # to improve the performance.
- #
- # By default Privoxy tries to discourage clients from pipelining
- # by discarding aggressively pipelined requests, which forces
- # the client to resend them through a new connection.
- #
- # This option lets Privoxy tolerate pipelining. Whether or not
- # that improves performance mainly depends on the client
- # configuration.
- #
- # If you are seeing problems with pages not properly loading,
- # disabling this option could work around the problem.
- #
- # Examples:
- #
- # tolerate-pipelining 1
- #
- tolerate-pipelining 1
- #
- # 6.6. 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
- #
- # 6.7. 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

- # 6.8. 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. 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.
- #
- # One most POSIX-compliant systems Privoxy can't properly deal
- # with more than FD_SETSIZE file descriptors at the same time
- # and has to reject connections if the limit is reached. This
- # will likely change in a future version, but currently this
- # limit can't be increased without recompiling Privoxy with a
- # different FD_SETSIZE limit.
- #
- # Examples:
- #
- # max-client-connections 256
- #
- #max-client-connections 256
- #
- # 6.10. 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
- #
- # 6.11. 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
- #
- # 6.12. 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
- #
- # 6.13. client-header-order
- # ==========================
- #
- # Specifies:
- #
- # The order in which client headers are sorted before forwarding
- # them.
- #
- # Type of value:
- #
- # Client header names delimited by spaces or tabs
- #
- # Default value:
- #
- # None
- #
- # Notes:
- #
- # By default Privoxy leaves the client headers in the order they
- # were sent by the client. Headers are modified in-place, new
- # headers are added at the end of the already existing headers.
- #
- # The header order can be used to fingerprint client requests
- # independently of other headers like the User-Agent.
- #
- # This directive allows to sort the headers differently to
- # better mimic a different User-Agent. Client headers will be
- # emitted in the order given, headers whose name isn't
- # explicitly specified are added at the end.
- #
- # Note that sorting headers in an uncommon way will make
- # fingerprinting actually easier. Encrypted headers are not
- # affected by this directive.
- #
- #client-header-order Host \
- # Accept \
- # Accept-Language \
- # Accept-Encoding \
- # Proxy-Connection \
- # Referer \
- # Cookie \
- # DNT \
- # If-Modified-Since \
- # Cache-Control \
- # Content-Length \
- # Content-Type
- #
- #
- # 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 copies log messages to the
- # console window. The log detail depends on the debug directive.
- #
- #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
