27 # This file holds Privoxy's main configuration. Privoxy detects
28 # configuration changes automatically, so you don't have to restart
29 # it unless you want to load a different configuration file.
31 # The configuration will be reloaded with the first request after
32 # the change was done, this request itself will still use the old
33 # configuration, though. In other words: it takes two requests
34 # before you see the result of your changes. Requests that are
35 # dropped due to ACL don't trigger reloads.
37 # When starting Privoxy on Unix systems, give the location of this
38 # file as last argument. On Windows systems, Privoxy will look for
39 # this file with the name 'config.txt' in the current working
40 # directory of the Privoxy process.
43 # II. FORMAT OF THE CONFIGURATION FILE
44 # ====================================
46 # Configuration lines consist of an initial keyword followed by a
47 # list of values, all separated by whitespace (any number of spaces
48 # or tabs). For example,
50 # actionsfile default.action
52 # Indicates that the actionsfile is named 'default.action'.
54 # The '#' indicates a comment. Any part of a line following a '#' is
55 # ignored, except if the '#' is preceded by a '\'.
57 # Thus, by placing a # at the start of an existing configuration
58 # line, you can make it a comment and it will be treated as if it
59 # weren't there. This is called "commenting out" an option and can
60 # be useful. Removing the # again is called "uncommenting".
62 # Note that commenting out an option and leaving it at its default
63 # are two completely different things! Most options behave very
64 # differently when unset. See the "Effect if unset" explanation in
65 # each option's description for details.
67 # Long lines can be continued on the next line by using a `\' as the
72 # 1. LOCAL SET-UP DOCUMENTATION
73 # ==============================
75 # If you intend to operate Privoxy for more users than just
76 # yourself, it might be a good idea to let them know how to reach
77 # you, what you block and why you do that, your policies, etc.
86 # Location of the Privoxy User Manual.
90 # A fully qualified URI
98 # http://www.privoxy.org/version/user-manual/ will be used,
99 # where version is the Privoxy version.
103 # The User Manual URI is the single best source of information
104 # on Privoxy, and is used for help links from some of the
105 # internal CGI pages. The manual itself is normally packaged
106 # with the binary distributions, so you probably want to set
107 # this to a locally installed copy.
111 # The best all purpose solution is simply to put the full local
112 # PATH to where the User Manual is located:
114 # user-manual /usr/share/doc/privoxy/user-manual
116 # The User Manual is then available to anyone with access to
117 # Privoxy, by following the built-in URL: http://
118 # config.privoxy.org/user-manual/ (or the shortcut: http://p.p/
121 # If the documentation is not on the local system, it can be
122 # accessed from a remote server, as:
124 # user-manual http://example.com/privoxy/user-manual/
128 # If set, this option should be the first option in the
129 # config file, because it is used while the config file is
132 #user-manual http://www.privoxy.org/user-manual/
135 # 1.2. trust-info-url
136 # ====================
140 # A URL to be displayed in the error page that users will see if
141 # access to an untrusted page is denied.
153 # No links are displayed on the "untrusted" error page.
157 # The value of this option only matters if the experimental
158 # trust mechanism has been activated. (See trustfile below.)
160 # If you use the trust mechanism, it is a good idea to write up
161 # some on-line documentation about your trust policy and to
162 # specify the URL(s) here. Use multiple times for multiple URLs.
164 # The URL(s) should be added to the trustfile as well, so users
165 # don't end up locked out from the information on why they were
166 # locked out in the first place!
168 #trust-info-url http://www.example.com/why_we_block.html
169 #trust-info-url http://www.example.com/what_we_allow.html
173 # ===================
177 # An email address to reach the Privoxy administrator.
189 # No email address is displayed on error pages and the CGI user
194 # If both admin-address and proxy-info-url are unset, the whole
195 # "Local Privoxy Support" box on all generated pages will not be
198 #admin-address privoxy-admin@example.com
201 # 1.4. proxy-info-url
202 # ====================
206 # A URL to documentation about the local Privoxy setup,
207 # configuration or policies.
219 # No link to local documentation is displayed on error pages and
220 # the CGI user interface.
224 # If both admin-address and proxy-info-url are unset, the whole
225 # "Local Privoxy Support" box on all generated pages will not be
228 # This URL shouldn't be blocked ;-)
230 #proxy-info-url http://www.example.com/proxy-service.html
233 # 2. CONFIGURATION AND LOG FILE LOCATIONS
234 # ========================================
236 # Privoxy can (and normally does) use a number of other files for
237 # additional configuration, help and logging. This section of the
238 # configuration file tells Privoxy where to find those other files.
240 # The user running Privoxy, must have read permission for all
241 # configuration files, and write permission to any files that would
242 # be modified, such as log files and actions files.
251 # The directory where the other configuration files are located.
259 # /etc/privoxy (Unix) or Privoxy installation dir (Windows)
267 # No trailing "/", please.
277 # An alternative directory where the templates are loaded from.
289 # The templates are assumed to be located in confdir/template.
293 # Privoxy's original templates are usually overwritten with each
294 # update. Use this option to relocate customized templates that
295 # should be kept. As template variables might change between
296 # updates, you shouldn't expect templates to work with Privoxy
297 # releases other than the one they were part of, though.
307 # The directory where all logging takes place (i.e. where the
308 # logfile is located).
316 # /var/log/privoxy (Unix) or Privoxy installation dir (Windows)
324 # No trailing "/", please.
334 # The actions file(s) to use
338 # Complete file name, relative to confdir
342 # match-all.action # Actions that are applied to all sites and maybe overruled later on.
344 # default.action # Main actions file
346 # user.action # User customizations
350 # No actions are taken at all. More or less neutral proxying.
354 # Multiple actionsfile lines are permitted, and are in fact
357 # The default values are default.action, which is the "main"
358 # actions file maintained by the developers, and user.action,
359 # where you can make your personal additions.
361 # Actions files contain all the per site and per URL
362 # configuration for ad blocking, cookie management, privacy
363 # considerations, etc. There is no point in using Privoxy
364 # without at least one actions file.
366 # Note that since Privoxy 3.0.7, the complete filename,
367 # including the ".action" extension has to be specified. The
368 # syntax change was necessary to be consistent with the other
369 # file options and to allow previously forbidden characters.
371 actionsfile match-all.action # Actions that are applied to all sites and maybe overruled later on.
372 actionsfile default.action # Main actions file
373 actionsfile user.action # User customizations
381 # The filter file(s) to use
385 # File name, relative to confdir
389 # default.filter (Unix) or default.filter.txt (Windows)
393 # No textual content filtering takes place, i.e. all +filter{name}
394 # actions in the actions files are turned neutral.
398 # Multiple filterfile lines are permitted.
400 # The filter files contain content modification rules that use
401 # regular expressions. These rules permit powerful changes on
402 # the content of Web pages, and optionally the headers as well,
403 # e.g., you could try to disable your favorite JavaScript
404 # annoyances, re-write the actual displayed text, or just have
405 # some fun playing buzzword bingo with web pages.
407 # The +filter{name} actions rely on the relevant filter (name)
408 # to be defined in a filter file!
410 # A pre-defined filter file called default.filter that contains
411 # a number of useful filters for common problems is included in
412 # the distribution. See the section on the filter action for a
415 # It is recommended to place any locally adapted filters into a
416 # separate file, such as user.filter.
418 filterfile default.filter
419 filterfile user.filter # User customizations
427 # The log file to use
431 # File name, relative to logdir
435 # Unset (commented out). When activated: logfile (Unix) or
436 # privoxy.log (Windows).
440 # No logfile is written.
444 # The logfile is where all logging and error messages are
445 # written. The level of detail and number of messages are set
446 # with the debug option (see below). The logfile can be useful
447 # for tracking down a problem with Privoxy (e.g., it's not
448 # blocking an ad you think it should block) and it can help you
449 # to monitor what your browser is doing.
451 # Depending on the debug options below, the logfile may be a
452 # privacy risk if third parties can get access to it. As most
453 # users will never look at it, Privoxy 3.0.7 and later only log
454 # fatal errors by default.
456 # For most troubleshooting purposes, you will have to change
457 # that, please refer to the debugging section for details.
459 # Your logfile will grow indefinitely, and you will probably
460 # want to periodically remove it. On Unix systems, you can do
461 # this with a cron job (see "man cron").
463 # Any log files must be writable by whatever user Privoxy is
464 # being run as (on Unix, default user id is "privoxy").
474 # The name of the trust file to use
478 # File name, relative to confdir
482 # Unset (commented out). When activated: trust (Unix) or
483 # trust.txt (Windows)
487 # The entire trust mechanism is disabled.
491 # The trust mechanism is an experimental feature for building
492 # white-lists and should be used with care. It is NOT
493 # recommended for the casual user.
495 # If you specify a trust file, Privoxy will only allow access to
496 # sites that are specified in the trustfile. Sites can be listed
497 # in one of two ways:
499 # Prepending a ~ character limits access to this site only (and
500 # any sub-paths within this site), e.g. ~www.example.com allows
501 # access to ~www.example.com/features/news.html, etc.
503 # Or, you can designate sites as trusted referrers, by
504 # prepending the name with a + character. The effect is that
505 # access to untrusted sites will be granted -- but only if a
506 # link from this trusted referrer was used to get there. The
507 # link target will then be added to the "trustfile" so that
508 # future, direct accesses will be granted. Sites added via this
509 # mechanism do not become trusted referrers themselves (i.e.
510 # they are added with a ~ designation). There is a limit of 512
511 # such entries, after which new entries will not be made.
513 # If you use the + operator in the trust file, it may grow
514 # considerably over time.
516 # It is recommended that Privoxy be compiled with the
517 # --disable-force, --disable-toggle and --disable-editor
518 # options, if this feature is to be used.
520 # Possible applications include limiting Internet access for
529 # These options are mainly useful when tracing a problem. Note that
530 # you might also want to invoke Privoxy with the --no-daemon command
531 # line option when debugging.
540 # Key values that determine what information gets logged.
548 # 0 (i.e.: only fatal errors (that cause Privoxy to exit) are
553 # Default value is used (see above).
557 # The available debug levels are:
559 # debug 1 # Log the destination for each request Privoxy let through. See also debug 1024.
560 # debug 2 # show each connection status
561 # debug 4 # show I/O status
562 # debug 8 # show header parsing
563 # debug 16 # log all data written to the network
564 # debug 32 # debug force feature
565 # debug 64 # debug regular expression filters
566 # debug 128 # debug redirects
567 # debug 256 # debug GIF de-animation
568 # debug 512 # Common Log Format
569 # debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
570 # debug 2048 # CGI user interface
571 # debug 4096 # Startup banner and warnings.
572 # debug 8192 # Non-fatal errors
573 # debug 32768 # log all data read from the network
574 # debug 65536 # Log the applying actions
576 # To select multiple debug levels, you can either add them or
577 # use multiple debug lines.
579 # A debug level of 1 is informative because it will show you
580 # each request as it happens. 1, 1024, 4096 and 8192 are
581 # recommended so that you will notice when things go wrong. The
582 # other levels are probably only of interest if you are hunting
583 # down a specific problem. They can produce a hell of an output
586 # Privoxy used to ship with the debug levels recommended above
587 # enabled by default, but due to privacy concerns 3.0.7 and
588 # later are configured to only log fatal errors.
590 # If you are used to the more verbose settings, simply enable
591 # the debug lines below again.
593 # If you want to use pure CLF (Common Log Format), you should
594 # set "debug 512" ONLY and not enable anything else.
596 # Privoxy has a hard-coded limit for the length of log messages.
597 # If it's reached, messages are logged truncated and marked with
598 # "... [too long, truncated]".
600 # Please don't file any support requests without trying to
601 # reproduce the problem with increased debug level first. Once
602 # you read the log messages, you may even be able to solve the
603 # problem on your own.
605 #debug 1 # Log the destination for each request Privoxy let through. See also debug 1024.
606 #debug 1024 # Actions that are applied to all sites and maybe overruled later on.
607 #debug 4096 # Startup banner and warnings
608 #debug 8192 # Non-fatal errors
611 # 3.2. single-threaded
612 # =====================
616 # Whether to run only one server thread.
628 # Multi-threaded (or, where unavailable: forked) operation, i.e.
629 # the ability to serve multiple requests simultaneously.
633 # This option is only there for debugging purposes. It will
634 # drastically reduce performance.
644 # The hostname shown on the CGI pages.
656 # The hostname provided by the operating system is used.
660 # On some misconfigured systems resolving the hostname fails or
661 # takes too much time and slows Privoxy down. Setting a fixed
662 # hostname works around the problem.
664 # In other circumstances it might be desirable to show a
665 # hostname other than the one returned by the operating system.
666 # For example if the system has several different hostnames and
667 # you don't want to use the first one.
669 # Note that Privoxy does not validate the specified hostname
672 #hostname hostname.example.org
675 # 4. ACCESS CONTROL AND SECURITY
676 # ===============================
678 # This section of the config file controls the security-relevant
679 # aspects of Privoxy's configuration.
683 # 4.1. listen-address
684 # ====================
688 # The address and TCP port on which Privoxy will listen for
703 # Bind to 127.0.0.1 (IPv4 localhost), port 8118. This is
704 # suitable and recommended for home users who run Privoxy on the
705 # same machine as their browser.
709 # You will need to configure your browser(s) to this proxy
712 # If you already have another service running on port 8118, or
713 # if you want to serve requests from other machines (e.g. on
714 # your local network) as well, you will need to override the
717 # You can use this statement multiple times to make Privoxy
718 # listen on more ports or more IP addresses. Suitable if your
719 # operating system does not support sharing IPv6 and IPv4
720 # protocols on the same socket.
722 # If a hostname is used instead of an IP address, Privoxy will
723 # try to resolve it to an IP address and if there are multiple,
724 # use the first one returned.
726 # If the address for the hostname isn't already known on the
727 # system (for example because it's in /etc/hostname), this may
728 # result in DNS traffic.
730 # If the specified address isn't available on the system, or if
731 # the hostname can't be resolved, Privoxy will fail to start.
733 # IPv6 addresses containing colons have to be quoted by
734 # brackets. They can only be used if Privoxy has been compiled
735 # with IPv6 support. If you aren't sure if your version supports
736 # it, have a look at http://config.privoxy.org/show-status.
738 # Some operating systems will prefer IPv6 to IPv4 addresses even
739 # if the system has no IPv6 connectivity which is usually not
740 # expected by the user. Some even rely on DNS to resolve
741 # localhost which mean the "localhost" address used may not
744 # It is therefore recommended to explicitly configure the
745 # intended IP address instead of relying on the operating
746 # system, unless there's a strong reason not to.
748 # If you leave out the address, Privoxy will bind to all IPv4
749 # interfaces (addresses) on your machine and may become
750 # reachable from the Internet and/or the local network. Be aware
751 # that some GNU/Linux distributions modify that behaviour
752 # without updating the documentation. Check for non-standard
753 # patches if your Privoxy version behaves differently.
755 # If you configure Privoxy to be reachable from the network,
756 # consider using access control lists (ACL's, see below), and/or
759 # If you open Privoxy to untrusted users, you will also want to
760 # make sure that the following actions are disabled:
761 # enable-edit-actions and enable-remote-toggle
765 # Suppose you are running Privoxy on a machine which has the
766 # address 192.168.0.1 on your local private network
767 # (192.168.0.0) and has another outside connection with a
768 # different address. You want it to serve requests from inside
771 # listen-address 192.168.0.1:8118
773 # Suppose you are running Privoxy on an IPv6-capable machine and
774 # you want it to listen on the IPv6 address of the loopback
777 # listen-address [::1]:8118
779 listen-address 127.0.0.1:8118
787 # Initial state of "toggle" status
799 # Act as if toggled on
803 # If set to 0, Privoxy will start in "toggled off" mode, i.e.
804 # mostly behave like a normal, content-neutral proxy with both
805 # ad blocking and content filtering disabled. See
806 # enable-remote-toggle below.
811 # 4.3. enable-remote-toggle
812 # ==========================
816 # Whether or not the web-based toggle feature may be used
828 # The web-based toggle feature is disabled.
832 # When toggled off, Privoxy mostly acts like a normal,
833 # content-neutral proxy, i.e. doesn't block ads or filter
836 # Access to the toggle feature can not be controlled separately
837 # by "ACLs" or HTTP authentication, so that everybody who can
838 # access Privoxy (see "ACLs" and listen-address above) can
839 # toggle it for all users. So this option is not recommended for
840 # multi-user environments with untrusted users.
842 # Note that malicious client side code (e.g Java) is also
843 # capable of using this option.
845 # As a lot of Privoxy users don't read documentation, this
846 # feature is disabled by default.
848 # Note that you must have compiled Privoxy with support for this
849 # feature, otherwise this option has no effect.
851 enable-remote-toggle 0
854 # 4.4. enable-remote-http-toggle
855 # ===============================
859 # Whether or not Privoxy recognizes special HTTP headers to
860 # change its behaviour.
872 # Privoxy ignores special HTTP headers.
876 # When toggled on, the client can change Privoxy's behaviour by
877 # setting special HTTP headers. Currently the only supported
878 # special header is "X-Filter: No", to disable filtering for the
879 # ongoing request, even if it is enabled in one of the action
882 # This feature is disabled by default. If you are using Privoxy
883 # in a environment with trusted clients, you may enable this
884 # feature at your discretion. Note that malicious client side
885 # code (e.g Java) is also capable of using this feature.
887 # This option will be removed in future releases as it has been
888 # obsoleted by the more general header taggers.
890 enable-remote-http-toggle 0
893 # 4.5. enable-edit-actions
894 # =========================
898 # Whether or not the web-based actions file editor may be used
910 # The web-based actions file editor is disabled.
914 # Access to the editor can not be controlled separately by
915 # "ACLs" or HTTP authentication, so that everybody who can
916 # access Privoxy (see "ACLs" and listen-address above) can
917 # modify its configuration for all users.
919 # This option is not recommended for environments with untrusted
920 # users and as a lot of Privoxy users don't read documentation,
921 # this feature is disabled by default.
923 # Note that malicious client side code (e.g Java) is also
924 # capable of using the actions editor and you shouldn't enable
925 # this options unless you understand the consequences and are
926 # sure your browser is configured correctly.
928 # Note that you must have compiled Privoxy with support for this
929 # feature, otherwise this option has no effect.
931 enable-edit-actions 0
934 # 4.6. enforce-blocks
935 # ====================
939 # Whether the user is allowed to ignore blocks and can "go there
952 # Blocks are not enforced.
956 # Privoxy is mainly used to block and filter requests as a
957 # service to the user, for example to block ads and other junk
958 # that clogs the pipes. Privoxy's configuration isn't perfect
959 # and sometimes innocent pages are blocked. In this situation it
960 # makes sense to allow the user to enforce the request and have
961 # Privoxy ignore the block.
963 # In the default configuration Privoxy's "Blocked" page contains
964 # a "go there anyway" link to adds a special string (the force
965 # prefix) to the request URL. If that link is used, Privoxy will
966 # detect the force prefix, remove it again and let the request
969 # Of course Privoxy can also be used to enforce a network
970 # policy. In that case the user obviously should not be able to
971 # bypass any blocks, and that's what the "enforce-blocks" option
972 # is for. If it's enabled, Privoxy hides the "go there anyway"
973 # link. If the user adds the force prefix by hand, it will not
974 # be accepted and the circumvention attempt is logged.
983 # 4.7. ACLs: permit-access and deny-access
984 # =========================================
988 # Who can access what.
992 # src_addr[:port][/src_masklen] [dst_addr[:port][/dst_masklen]]
994 # Where src_addr and dst_addr are IPv4 addresses in dotted
995 # decimal notation or valid DNS names, port is a port number,
996 # and src_masklen and dst_masklen are subnet masks in CIDR
997 # notation, i.e. integer values from 2 to 30 representing the
998 # length (in bits) of the network address. The masks and the
999 # whole destination part are optional.
1001 # If your system implements RFC 3493, then src_addr and dst_addr
1002 # can be IPv6 addresses delimeted by brackets, port can be a
1003 # number or a service name, and src_masklen and dst_masklen can
1004 # be a number from 0 to 128.
1010 # If no port is specified, any port will match. If no
1011 # src_masklen or src_masklen is given, the complete IP address
1012 # has to match (i.e. 32 bits for IPv4 and 128 bits for IPv6).
1016 # Don't restrict access further than implied by listen-address
1020 # Access controls are included at the request of ISPs and
1021 # systems administrators, and are not usually needed by
1022 # individual users. For a typical home user, it will normally
1023 # suffice to ensure that Privoxy only listens on the localhost
1024 # (127.0.0.1) or internal (home) network address by means of the
1025 # listen-address option.
1027 # Please see the warnings in the FAQ that Privoxy is not
1028 # intended to be a substitute for a firewall or to encourage

1031 # Multiple ACL lines are OK. If any ACLs are specified, Privoxy
1032 # only talks to IP addresses that match at least one
1033 # permit-access line and don't match any subsequent deny-access
1034 # line. In other words, the last match wins, with the default
1035 # being deny-access.
1037 # If Privoxy is using a forwarder (see forward below) for a
1038 # particular destination URL, the dst_addr that is examined is
1039 # the address of the forwarder and NOT the address of the
1040 # ultimate target. This is necessary because it may be
1041 # impossible for the local Privoxy to determine the IP address
1042 # of the ultimate target (that's often what gateways are used
1045 # You should prefer using IP addresses over DNS names, because
1046 # the address lookups take time. All DNS names must resolve! You
1047 # can not use domain patterns like "*.org" or partial domain
1048 # names. If a DNS name resolves to multiple IP addresses, only
1049 # the first one is used.
1051 # Some systems allow IPv4 clients to connect to IPv6 server
1052 # sockets. Then the client's IPv4 address will be translated by
1053 # the system into IPv6 address space with special prefix
1054 # ::ffff:0:0/96 (so called IPv4 mapped IPv6 address). Privoxy
1055 # can handle it and maps such ACL addresses automatically.
1057 # Denying access to particular sites by ACL may have undesired
1058 # side effects if the site in question is hosted on a machine
1059 # which also hosts other sites (most sites are).
1063 # Explicitly define the default behavior if no ACL and
1064 # listen-address are set: "localhost" is OK. The absence of a
1065 # dst_addr implies that all destination addresses are OK:

1112 # Use a 4MB (4096 KB) limit.
1116 # For content filtering, i.e. the +filter and +deanimate-gif
1117 # actions, it is necessary that Privoxy buffers the entire
1118 # document body. This can be potentially dangerous, since a
1119 # server could just keep sending data indefinitely and wait for
1120 # your RAM to exhaust -- with nasty consequences. Hence this
1123 # When a document buffer size reaches the buffer-limit, it is
1124 # flushed to the client unfiltered and no further attempt to
1125 # filter the rest of the document is made. Remember that there
1126 # may be multiple threads running, which might require up to
1127 # buffer-limit Kbytes each, unless you have enabled
1128 # "single-threaded" above.

1143 # Note that parent proxies can severely decrease your privacy level.
1144 # For example a parent proxy could add your IP address to the
1145 # request headers and if it's a caching proxy it may add the "Etag"
1146 # header to revalidation requests again, even though you configured

1264 # remote server as well.
1266 # forward-socks5t works like vanilla forward-socks5 but lets
1267 # Privoxy additionally use Tor-specific SOCKS extensions.
1268 # Currently the only supported SOCKS extension is optimistic
1269 # data which can reduce the latency for the first request made

1298 # To chain Privoxy and Tor, both running on the same system, you
1299 # would use something like:

1303 # The public Tor network can't be used to reach your local

1311 # Unencrypted connections to systems in these address ranges
1312 # will be as (un)secure as the local network is, but the
1313 # alternative is that you can't reach the local network through
1314 # Privoxy at all. Of course this may actually be desired and
1315 # there is no reason to make these exceptions if you aren't sure
1318 # If you also want to be able to reach servers in your local
1319 # network by using their names, you will need additional

1326 # 5.3. forwarded-connect-retries
1327 # ===============================
1331 # How often Privoxy retries if a forwarded connection request
1336 # Number of retries.
1344 # Connections forwarded through other proxies are treated like
1345 # direct connections and no retry attempts are made.
1349 # forwarded-connect-retries is mainly interesting for socks4a
1350 # connections, where Privoxy can't detect why the connections
1351 # failed. The connection might have failed because of a DNS
1352 # timeout in which case a retry makes sense, but it might also
1353 # have failed because the server doesn't exist or isn't
1354 # reachable. In this case the retry will just delay the
1355 # appearance of Privoxy's error message.
1357 # Note that in the context of this option, "forwarded
1358 # connections" includes all connections that Privoxy forwards
1359 # through other proxies. This option is not limited to the HTTP
1362 # Only use this option, if you are getting lots of
1363 # forwarding-related error messages that go away when you try
1364 # again manually. Start with a small value and check Privoxy's
1365 # logfile from time to time, to see how many retries are usually

1379 # 6.1. accept-intercepted-requests
1380 # =================================
1384 # Whether intercepted requests should be treated as valid.
1396 # Only proxy requests are accepted, intercepted requests are
1397 # treated as invalid.
1401 # If you don't trust your clients and want to force them to use
1402 # Privoxy, enable this option and configure your packet filter
1403 # to redirect outgoing HTTP connections into Privoxy.
1405 # Make sure that Privoxy's own requests aren't redirected as
1406 # well. Additionally take care that Privoxy can't intentionally
1407 # connect to itself, otherwise you could run into redirection
1408 # loops if Privoxy's listening port is reachable by the outside

1413 # accept-intercepted-requests 1
1415 accept-intercepted-requests 0
1418 # 6.2. allow-cgi-request-crunching
1419 # =================================
1423 # Whether requests to Privoxy's CGI pages can be blocked or
1436 # Privoxy ignores block and redirect actions for its CGI pages.
1440 # By default Privoxy ignores block or redirect actions for its
1441 # CGI pages. Intercepting these requests can be useful in
1442 # multi-user setups to implement fine-grained access control,
1443 # but it can also render the complete web interface useless and
1444 # make debugging problems painful if done without care.

1456 # 6.3. split-large-forms
1457 # =======================
1461 # Whether the CGI interface should stay compatible with broken
1474 # The CGI form generate long GET URLs.
1478 # Privoxy's CGI forms can lead to rather long URLs. This isn't a
1479 # problem as far as the HTTP standard is concerned, but it can
1480 # confuse clients with arbitrary URL length limitations.
1482 # Enabling split-large-forms causes Privoxy to divide big forms
1483 # into smaller ones to keep the URL length down. It makes
1484 # editing a lot less convenient and you can no longer submit all
1485 # changes at once, but at least it works around this browser
1488 # If you don't notice any editing problems, there is no reason
1489 # to enable this option, but if one of the submit buttons
1490 # appears to be broken, you should give it a try.
1494 # split-large-forms 1
1499 # 6.4. keep-alive-timeout
1500 # ========================
1504 # Number of seconds after which an open connection will no
1517 # Connections are not kept alive.
1521 # This option allows clients to keep the connection to Privoxy
1522 # alive. If the server supports it, Privoxy will keep the
1523 # connection to the server alive as well. Under certain
1524 # circumstances this may result in speed-ups.
1526 # By default, Privoxy will close the connection to the server if
1527 # the client connection gets closed, or if the specified timeout
1528 # has been reached without a new request coming in. This
1529 # behaviour can be changed with the connection-sharing option.
1531 # This option has no effect if Privoxy has been compiled without
1532 # keep-alive support.
1534 # Note that a timeout of five seconds as used in the default
1535 # configuration file significantly decreases the number of
1536 # connections that will be reused. The value is used because
1537 # some browsers limit the number of connections they open to a
1538 # single host and apply the same limit to proxies. This can
1539 # result in a single website "grabbing" all the connections the
1540 # browser allows, which means connections to other websites
1541 # can't be opened until the connections currently in use time
1544 # Several users have reported this as a Privoxy bug, so the
1545 # default value has been reduced. Consider increasing it to 300
1546 # seconds or even more if you think your browser can handle it.
1547 # If your browser appears to be hanging, it probably can't.

1556 # 6.5. tolerate-pipelining
1557 # =========================
1561 # Whether or not pipelined requests should be served.
1573 # If Privoxy receives more than one request at once, it
1574 # terminates the client connection after serving the first one.
1578 # Privoxy currently doesn't pipeline outgoing requests, thus
1579 # allowing pipelining on the client connection is not guaranteed
1580 # to improve the performance.
1582 # By default Privoxy tries to discourage clients from pipelining
1583 # by discarding aggressively pipelined requests, which forces
1584 # the client to resend them through a new connection.
1586 # This option lets Privoxy tolerate pipelining. Whether or not
1587 # that improves performance mainly depends on the client
1590 # If you are seeing problems with pages not properly loading,
1591 # disabling this option could work around the problem.

1601 # ============================
1605 # Assumed server-side keep-alive timeout if not specified by the
1618 # Connections for which the server didn't specify the keep-alive
1619 # timeout are not reused.
1623 # Enabling this option significantly increases the number of
1624 # connections that are reused, provided the keep-alive-timeout
1625 # option is also enabled.
1627 # While it also increases the number of connections problems
1628 # when Privoxy tries to reuse a connection that already has been
1629 # closed on the server side, or is closed while Privoxy is
1630 # trying to reuse it, this should only be a problem if it
1631 # happens for the first request sent by the client. If it
1632 # happens for requests on reused client connections, Privoxy
1633 # will simply close the connection and the client is supposed to
1634 # retry the request without bothering the user.
1636 # Enabling this option is therefore only recommended if the
1637 # connection-sharing option is disabled.
1639 # It is an error to specify a value larger than the
1640 # keep-alive-timeout value.

1652 # 6.7. connection-sharing
1653 # ========================
1657 # Whether or not outgoing connections that have been kept alive
1658 # should be shared between different incoming connections.
1670 # Connections are not shared.
1674 # This option has no effect if Privoxy has been compiled without
1675 # keep-alive support, or if it's disabled.
1679 # Note that reusing connections doesn't necessary cause
1680 # speedups. There are also a few privacy implications you should
1683 # If this option is effective, outgoing connections are shared
1684 # between clients (if there are more than one) and closing the
1685 # browser that initiated the outgoing connection does no longer
1686 # affect the connection between Privoxy and the server unless
1687 # the client's request hasn't been completed yet.
1689 # If the outgoing connection is idle, it will not be closed
1690 # until either Privoxy's or the server's timeout is reached.
1691 # While it's open, the server knows that the system running
1692 # Privoxy is still there.
1694 # If there are more than one client (maybe even belonging to
1695 # multiple users), they will be able to reuse each others
1696 # connections. This is potentially dangerous in case of
1697 # authentication schemes like NTLM where only the connection is
1698 # authenticated, instead of requiring authentication for each
1701 # If there is only a single client, and if said client can keep
1702 # connections alive on its own, enabling this option has next to
1703 # no effect. If the client doesn't support connection
1704 # keep-alive, enabling this option may make sense as it allows
1705 # Privoxy to keep outgoing connections alive even if the client
1706 # itself doesn't support it.
1708 # You should also be aware that enabling this option increases
1709 # the likelihood of getting the "No server or forwarder data"
1710 # error message, especially if you are using a slow connection

1714 # understand the risks and can weight them against the benefits.

1724 # ====================
1728 # Number of seconds after which a socket times out if no data is
1741 # A default value of 300 seconds is used.
1745 # The default is quite high and you probably want to reduce it.
1746 # If you aren't using an occasionally slow proxy like Tor,

1756 # 6.9. max-client-connections
1757 # ============================
1761 # Maximum number of client connections that will be served.
1773 # Connections are served until a resource limit is reached.
1777 # Privoxy creates one thread (or process) for every incoming
1778 # client connection that isn't rejected based on the access
1781 # If the system is powerful enough, Privoxy can theoretically
1782 # deal with several hundred (or thousand) connections at the
1783 # same time, but some operating systems enforce resource limits
1784 # by shutting down offending processes and their default limits
1785 # may be below the ones Privoxy would require under heavy load.
1787 # Configuring Privoxy to enforce a connection limit below the
1788 # thread or process limit used by the operating system makes
1789 # sure this doesn't happen. Simply increasing the operating
1790 # system's limit would work too, but if Privoxy isn't the only
1791 # application running on the system, you may actually want to
1792 # limit the resources used by Privoxy.
1794 # If Privoxy is only used by a single trusted user, limiting the
1795 # number of client connections is probably unnecessary. If there
1796 # are multiple possibly untrusted users you probably still want
1797 # to additionally use a packet filter to limit the maximal
1798 # number of incoming connections per client. Otherwise a
1799 # malicious user could intentionally create a high number of
1800 # connections to prevent other users from using Privoxy.

1957 # This directive allows to sort the headers differently to
1958 # better mimic a different User-Agent. Client headers will be
1959 # emitted in the order given, headers whose name isn't
1960 # explicitly specified are added at the end.

1963 # fingerprinting actually easier. Encrypted headers are not

1981 # =======================
1983 # Privoxy has a number of options specific to the Windows GUI
1988 # If "activity-animation" is set to 1, the Privoxy icon will animate
1989 # when "Privoxy" is active. To turn off, set to 0.
1991 #activity-animation 1
1995 # If "log-messages" is set to 1, Privoxy copies log messages to the
1996 # console window. The log detail depends on the debug directive.
2002 # If "log-buffer-size" is set to 1, the size of the log buffer, i.e.
2003 # the amount of memory used for the log messages displayed in the
2004 # console window, will be limited to "log-max-lines" (see below).
2006 # Warning: Setting this to 0 will result in the buffer to grow
2007 # infinitely and eat up all your memory!
2013 # log-max-lines is the maximum number of lines held in the log
2014 # buffer. See above.
2020 # If "log-highlight-messages" is set to 1, Privoxy will highlight
2021 # portions of the log messages with a bold-faced font:
2023 #log-highlight-messages 1
2027 # The font used in the console window:
2029 #log-font-name Comic Sans MS
2033 # Font size used in the console window:
2039 # "show-on-task-bar" controls whether or not Privoxy will appear as
2040 # a button on the Task bar when minimized:
2046 # If "close-button-minimizes" is set to 1, the Windows close button
2047 # will minimize Privoxy instead of closing the program (close with
2048 # the exit option on the File menu).
2050 #close-button-minimizes 1
2054 # The "hide-console" option is specific to the MS-Win console
2055 # version of Privoxy. If this option is used, Privoxy will
2056 # disconnect from and hide the command console.
