105 This documentation is included with the current &p-status; version of
106 <application>Privoxy</application>, v.&p-version;<![%p-not-stable;[,
107 and is mostly complete at this point. The most up to date reference for the
108 time being is still the comments in the source files and in the individual
109 configuration files. Development of version 3.0 is currently nearing
110 completion, and includes many significant changes and enhancements over
111 earlier versions. The target release date for
112 stable v3.0 is <quote>soon</quote> ;-)]]>.
115 <!-- include only in non-stable versions -->
118 Since this is a &p-status; version, not all new features are well tested. This
119 documentation may be slightly out of sync as a result (especially with
120 CVS sources). And there <emphasis>may be</emphasis> bugs, though hopefully

146 <sect1 id="installation"><title>Installation</title>
149 <application>Privoxy</application> is available both in convenient pre-compiled
150 packages for a wide range of operating systems, and as raw source code.
151 For most users, we recommend using the packages, which can be downloaded from our
152 <ulink url="http://sourceforge.net/projects/ijbswa/">Privoxy Project Page</ulink>.
156 If you like to live on the bleeding edge and are not afraid of using
157 possibly unstable development versions, you can check out the up-to-the-minute
158 version directly from <ulink url="http://sourceforge.net/cvs/?group_id=11118">the

174 will need to remove it. Some platforms do this for you as part
175 of their installation procedure. (See below for your platform).
179 In any case <emphasis>be sure to backup your old configuration
180 if it is valuable to you.</emphasis> See the

185 How to install the binary packages depends on your operating system:
188 <!-- ~~~~~ New section ~~~~~ -->
189 <sect3 id="installation-pack-rpm"><title>Red Hat and SuSE RPMs</title>
192 RPMs can be installed with <literal>rpm -Uvh <name-of-rpm.rpm></literal>,
193 and will use <filename>/etc/privoxy</filename> for the location
194 of configuration files.
198 Note that if you have a <application>Junkbuster</application> RPM installed
199 on your system, you need to remove it first, because the packages conflict.
200 Otherwise, RPM will try to remove <application>Junkbuster</application>

298 <title>Note to Upgraders</title>
300 There are very significant changes from older versions of
301 <application>Junkbuster</application> to the current
302 <application>Privoxy</application>. Configuration is substantially
303 changed. <application>Junkbuster 2.0.x</application> and earlier
304 configuration files will not migrate. The functionality of the old
305 <filename>blockfile</filename>, <filename>cookiefile</filename> and
306 <filename>imagelist</filename>, are now combined into the
307 <quote>actions file</quote> (<filename>default.action</filename>
308 for most installations).
311 A <quote>filter file</quote> (typically <filename>default.filter</filename>)
312 is new as of <application>Privoxy 2.9.x</application>, and provides some
313 of the new sophistication (explained below). <filename>config</filename> is
314 much the same as before.
317 If upgrading from a 2.0.x version, you will have to use the new config
318 files, and possibly adapt any personal rules from your older files.
319 When porting personal rules over from the old <filename>blockfile</filename>
320 to the new actions file, please note that even the pattern syntax has
321 changed. If upgrading from 2.9.x development versions, it is still
322 recommended to use the new configuration files.
325 A quick list of things to be aware of before upgrading:
333 The default listening port is now 8118 due to a conflict with another
339 Some installers may remove earlier versions completely. Save any
340 important configuration files!
345 <application>Privoxy</application> is controllable with a web browser
346 at the special URL: <ulink
347 url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>
348 (Shortcut: <ulink url="http://p.p/">http://p.p/</ulink>). Many
349 aspects of configuration can be done here, including temporarily disabling
350 <application>Privoxy</application>.
355 The primary configuration file for cookie management, ad and banner
356 blocking, and many other aspects of <application>Privoxy</application>
357 configuration is <filename>default.action</filename>. It is strongly
358 recommended to become familiar with the new actions concept below,
359 before modifying this file.
364 <!-- I think it is best to keep this somewhat vague, in case -->
365 <!-- the situation changes under our feet. -->
366 Some installers may not automatically start
367 <application>Privoxy</application> after installation.
376 <!-- ~~~~~ New section ~~~~~ -->
378 <title>Starting <application>Privoxy</application></title>
380 Before launching <application>Privoxy</application> for the first time, you
381 will want to configure your browser(s) to use <application>Privoxy</application>
382 as a HTTP and HTTPS proxy. The default is localhost for the proxy address,
383 and port 8118 (earlier versions used port 8000). This is the one
384 configuration step that must be done!
388 With <application>Netscape</application> (and
389 <application>Mozilla</application>), this can be set under <literal>Edit
390 -> Preferences -> Advanced -> Proxies -> HTTP Proxy</literal>.
391 For <application>Internet Explorer</application>: <literal>Tools ->
392 Internet Properties -> Connections -> LAN Setting</literal>. Then,
393 check <quote>Use Proxy</quote> and fill in the appropriate info (Address:
394 localhost, Port: 8118). Include if HTTPS proxy support too.
398 After doing this, flush your browser's disk and memory caches to force a
399 re-reading of all pages and to get rid of any ads that may be cached. You
400 are now ready to start enjoying the benefits of using
401 <application>Privoxy</application>!
406 <application>Privoxy</application> is typically started by specifying the
407 main configuration file to be used on the command line. Example Unix startup
414 # /usr/sbin/privoxy /etc/privoxy/config
420 See <link linkend="cmdoptions">below</link> for other command line options.
424 An init script is provided for SuSE and Red Hat.
428 For for SuSE: <command>rcprivoxy start</command>
432 For Red Hat: <command>/etc/rc.d/init.d/privoxy start</command>
437 If no configuration file is specified on the command line,
438 <application>Privoxy</application> will look for a file named
439 <filename>config</filename> in the current directory. Except on Win32 where
440 it will try <filename>config.txt</filename>. If no file is specified on the
441 command line and no default configuration file can be found,
442 <application>Privoxy</application> will fail to start.
447 The included default configuration files should give a reasonable starting
448 point. Most of the per site configuration is done in the
449 <quote>actions</quote> files. These are where various cookie actions are
450 defined, ad and banner blocking, and other aspects of
451 <application>Privoxy</application> configuration. There are several such
452 files included, with varying levels of aggressiveness.
456 You will probably want to keep an eye out for sites that require persistent
457 cookies, and add these to <filename>default.action</filename> as needed. By
458 default, most of these will be accepted only during the current browser
459 session (aka <quote>session cookies</quote>), until you add them to the
460 configuration. If you want the browser to handle this instead, you will need
461 to edit <filename>default.action</filename> and disable this feature. If you
462 use more than one browser, it would make more sense to let
463 <application>Privoxy</application> handle this. In which case, the
464 browser(s) should be set to accept all cookies.
468 Another feature where you will probably want to define exceptions for trusted
469 sites is the popup-killing (through the <literal>+popup</literal> and
470 <literal>+filter{popups}</literal> actions), because your favorite shopping,
471 banking, or leisure site may need popups.
475 <application>Privoxy</application> is HTTP/1.1 compliant, but not all of
476 the optional 1.1 features are as yet supported. In the unlikely event that
477 you experience inexplicable problems with browsers that use HTTP/1.1 per default
478 (like <application>Mozilla</application> or recent versions of I.E.), you might
479 try to force HTTP/1.0 compatibility. For Mozilla, look under <literal>Edit ->
480 Preferences -> Debug -> Networking</literal>.
481 Alternatively, set the <quote>+downgrade</quote> config option in
482 <filename>default.action</filename> which will downgrade your browser's HTTP
483 requests from HTTP/1.1 to HTTP/1.0 before processing them.
487 After running <application>Privoxy</application> for a while, you can
488 start to fine tune the configuration to suit your personal, or site,
489 preferences and requirements. There are many, many aspects that can
490 be customized. <quote>Actions</quote> (as specified in <filename>default.action</filename>)
491 can be adjusted by pointing your browser to
492 <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>
493 (shortcut: <ulink url="http://p.p/">http://p.p/</ulink>),
494 and then follow the link to <quote>edit the actions list</quote>.
495 (This is an internal page and does not require Internet access.)
499 In fact, various aspects of <application>Privoxy</application>
500 configuration can be viewed from this page, including
501 current configuration parameters, source code version numbers,
502 the browser's request headers, and <quote>actions</quote> that apply
503 to a given URL. In addition to the <filename>default.action</filename> file
504 editor mentioned above, <application>Privoxy</application> can also
505 be turned <quote>on</quote> and <quote>off</quote> (toggled) from this page.
509 If you encounter problems, try loading the page without
510 <application>Privoxy</application>. If that helps, enter the URL where
511 you have the problems into <ulink url="http://p.p/show-url-info">the browser
512 based rule tracing utility</ulink>. See which rules apply and why, and
513 then try turning them off for that site one after the other, until the problem
514 is gone. When you have found the culprit, you might want to turn the rest on

687 <title>Configuration Files Overview</title>
689 For Unix, *BSD and Linux, all configuration files are located in
690 <filename>/etc/privoxy/</filename> by default. For MS Windows, OS/2, and
691 AmigaOS these are all in the same directory as the
692 <application>Privoxy</application> executable. <![%p-not-stable;[ The name
693 and number of configuration files has changed from previous versions, and is
694 subject to change as development progresses.]]>
698 The installed defaults provide a reasonable starting point, though possibly
699 aggressive by some standards. For the time being, there are only three
700 default configuration files (this may change in time):
708 The main configuration file is named <filename>config</filename>
709 on Linux, Unix, BSD, OS/2, and AmigaOS and <filename>config.txt</filename>
716 <filename>default.action</filename> (the actions file) is used to define
717 which of a set of various <quote>actions</quote> relating to images, banners,
718 pop-ups, access restrictions, banners and cookies are to be applied, and where.
719 There is a web based editor for this file that can be accessed at <ulink
720 url="http://config.privoxy.org/edit-actions/">http://config.privoxy.org/edit-actions/</ulink>
721 (Shortcut: <ulink url="http://p.p/edit-actions/">http://p.p/edit-actions/</ulink>).
722 (Other actions files are included as well with differing levels of filtering
723 and blocking, e.g. <filename>basic.action</filename>.)
729 <filename>default.filter</filename> (the filter file) can be used to re-write the raw
730 page content, including viewable text as well as embedded HTML and JavaScript,
731 and whatever else lurks on any given web page. The filtering jobs are only
732 pre-defined here; whether to apply them or not is up to the actions file.
740 All files use the <quote><literal>#</literal></quote> character to denote a
741 comment (the rest of the line will be ignored) and understand line continuation
742 through placing a backslash ("<literal>\</literal>") as the very last character
743 in a line. If the <literal>#</literal> is preceded by a backslash, it looses
744 its special function. Placing a <literal>#</literal> in front of an otherwise
745 valid configuration line to prevent it from being interpreted is called "commenting
750 <filename>default.action</filename> and <filename>default.filter</filename>
751 can use Perl style <link linkend="regex">regular expressions</link> for
756 After making any changes, there is no need to restart
757 <application>Privoxy</application> in order for the changes to take
758 effect. <application>Privoxy</application> detects such changes
759 automatically. Note, however, that it may take one or two additional
760 requests for the change to take effect. When changing the listening address
761 of <application>Privoxy</application>, these <quote>wake up</quote> requests
762 must obviously be sent to the <emphasis>old</emphasis> listening address.
767 While under development, the configuration content is subject to change.
768 The below documentation may not be accurate by the time you read this.
769 Also, what constitutes a <quote>default</quote> setting, may change, so
770 please check all your configuration files on important issues.
776 <!-- ~~~~~ New section ~~~~~ -->
779 <title>The Main Configuration File</title>
781 Again, the main configuration file is named <filename>config</filename> on
782 Linux/Unix/BSD and OS/2, and <filename>config.txt</filename> on Windows.
783 Configuration lines consist of an initial keyword followed by a list of
784 values, all separated by whitespace (any number of spaces or tabs). For
792 <emphasis>confdir /etc/privoxy</emphasis>
799 Assigns the value <literal>/etc/privoxy</literal> to the option
800 <literal>confdir</literal> and thus indicates that the configuration
801 directory is named <quote>/etc/privoxy/</quote>.
805 All options in the config file except for <literal>confdir</literal> and
806 <literal>logdir</literal> are optional. Watch out in the below description
807 for what happens if you leave them unset.
811 The main config file controls all aspects of <application>Privoxy</application>'s
812 operation that are not location dependent (i.e. they apply universally, no matter
813 where you may be surfing).
817 <!-- ~~~~~ New section ~~~~~ -->
820 <title>Configuration and Log File Locations</title>
823 <application>Privoxy</application> can (and normally does) use a number of
824 other files for additional configuration and logging.

826 where to find those other files.

1758 Access controls are included at the request of ISPs and systems
1759 administrators, and <emphasis>are not usually needed by individual users</emphasis>.

1761 <application>Privoxy</application> only listens on the localhost or internal (home)
1762 network address by means of the <literal>listen-address</literal> option.
1765 Please see the warnings in the FAQ that this proxy is not intended to be a substitute
1766 for a firewall or to encourage anyone to defer addressing basic security
1770 Multiple ACL lines are OK.
1771 If any ACLs are specified, then the <application>Privoxy</application>
1772 talks only to IP addresses that match at least one <literal>permit-access</literal> line
1773 and don't match any subsequent <literal>deny-access</literal> line. In other words, the
1774 last match wins, with the default being <literal>deny-access</literal>.
1777 If <application>Privoxy</application> is using a forwarder (see <literal>forward</literal> below)
1778 for a particular destination URL, the <replaceable class="parameter">dst_addr</replaceable>
1779 that is examined is the address of the forwarder and <emphasis>NOT</emphasis> the address
1780 of the ultimate target. This is necessary because it may be impossible for the local
1781 <application>Privoxy</application> to determine the IP address of the
1782 ultimate target (that's often what gateways are used for).
1785 You should prefer using IP addresses over DNS names, because the address lookups take
1786 time. All DNS names must resolve! You can <emphasis>not</emphasis> use domain patterns
1787 like <quote>*.org</quote> or partial domain names. If a DNS name resolves to multiple
1788 IP addresses, only the first one is used.
1791 Denying access to particular sites by ACL may have undesired side effects
1792 if the site in question is hosted on a machine which also hosts other sites.
1797 <term>Examples:</term>
1800 Explicitly define the default behavior if no ACL and
1801 <literal>listen-address</literal> are set: <quote>localhost</quote>

2043 Multiple lines are OK, they are checked in sequence, and the last match wins.
2046 The difference between <literal>forward-socks4</literal> and <literal>forward-socks4a</literal>
2047 is that in the SOCKS 4A protocol, the DNS resolution of the target hostname happens on the SOCKS
2048 server, while in SOCKS 4 it happens locally.
2051 If <replaceable class="parameter">http_parent</replaceable> is <quote>.</quote>, then requests are not
2052 forwarded to another HTTP proxy but are made (HTTP-wise) directly to the web servers, albeit through
2058 <term>Examples:</term>
2061 From the company example.com, direct connections are made to all
2062 <quote>internal</quote> domains, but everything outbound goes through
2063 their ISP's proxy by way of example.com's corporate SOCKS 4A gateway to
2068 forward-socks4a .*. socks-gw.example.com:1080 www-cache.example-isp.net:8080
2069 forward .example.com .
2073 A rule that uses a SOCKS 4 gateway for all destinations but no HTTP parent looks like this:
2077 forward-socks4 .*. socks-gw.example.com:1080 .
2085 <sect4><title>Advanced Forwarding Examples</title>
2088 If you have links to multiple ISPs that provide various special content
2089 only to their subscribers, you can configure multiple <application>Privoxies</application>
2090 which have connections to the respective ISPs to act as forwarders to each other, so that
2091 <emphasis>your</emphasis> users can see the internal content of all ISPs.
2095 Assume that host-a has a PPP connection to isp-a.net. And host-b has a PPP connection to
2096 isp-b.net. Both run <application>Privoxy</application>. Their forwarding
2097 configuration can look like this:
2107 forward .isp-b.net host-b:8118
2118 forward .isp-a.net host-a:8118
2123 Now, your users can set their browser's proxy to use either
2124 host-a or host-b and be able to browse the internal content
2125 of both isp-a and isp-b.
2129 If you intend to chain <application>Privoxy</application> and
2130 <application>squid</application> locally, then chain as
2131 <literal>browser -> squid -> privoxy</literal> is the recommended way.
2135 Assuming that <application>Privoxy</application> and <application>squid</application>
2136 run on the same box, your squid configuration could then look like this:
2141 # Define Privoxy as parent proxy (without ICP)
2142 cache_peer 127.0.0.1 parent 8118 7 no-query
2144 # Define ACL for protocol FTP
2147 # Do not forward FTP requests to Privoxy
2148 always_direct allow ftp
2150 # Forward all the rest to Privoxy
2151 never_direct allow all
2156 You would then need to change your browser's proxy settings to <application>squid</application>'s address and port.
2157 Squid normally uses port 3128. If unsure consult <literal>http_port</literal> in <filename>squid.conf</filename>.

2209 If <quote>log-buffer-size</quote> is set to 1, the size of the log buffer,
2210 i.e. the amount of memory used for the log messages displayed in the
2211 console window, will be limited to <quote>log-max-lines</quote> (see below).
2215 Warning: Setting this to 0 will result in the buffer to grow infinitely and

2345 <title>The Actions File</title>
2348 The actions file (<filename>default.action</filename>, formerly:
2349 <filename>actionsfile</filename> or <filename>ijb.action</filename>) is used
2350 to define what actions <application>Privoxy</application> takes for which
2351 URLs, and thus determines how ad images, cookies and various other aspects
2352 of HTTP content and transactions are handled on which sites (or even parts
2357 Anything you want can blocked, including ads, banners, or just some obnoxious
2358 URL that you would rather not see. Cookies can be accepted or rejected, or
2359 accepted only during the current browser session (i.e. not written to disk),
2360 content can be modified, JavaScripts tamed, user-tracking fooled, and much more.
2361 See below for a complete list of available actions.
2365 An actions file typically has sections. At the top, <quote>aliases</quote> are
2366 defined (discussed below), then the default set of rules which will apply
2367 universally to all sites and pages. And then below that is generally a lengthy
2368 set of exceptions to the defined universal policies.
2371 <!-- ~~~~~ New section ~~~~~ -->
2373 <title>Finding the Right Mix</title>
2375 Note that some actions like cookie suppression or script disabling may
2376 render some sites unusable, which rely on these techniques to work properly.
2377 Finding the right mix of actions is not easy and certainly a matter of personal
2378 taste. In general, it can be said that the more <quote>aggressive</quote>
2379 your default settings (in the top section of the actions file) are,
2380 the more exceptions for <quote>trusted</quote> sites you will have to
2381 make later. If, for example, you want to kill popup windows per default, you'll
2382 have to make exceptions from that rule for sites that you regularly use
2383 and that require popups for actually useful content, like maybe your bank,
2384 favorite shop, or newspaper.
2388 We have tried to provide you with reasonable rules to start from in the
2389 distribution actions file. But there is no general rule of thumb on these
2390 things. There just are too many variables, and sites are constantly changing.
2391 Sooner or later you will want to change the rules (and read this chapter).
2395 <!-- ~~~~~ New section ~~~~~ -->
2397 <title>How to Edit</title>
2399 The easiest way to edit the <quote>actions</quote> file is with a browser by
2400 using our browser-based editor, which is available at <ulink
2401 url="http://config.privoxy.org/edit-actions">http://config.privoxy.org/edit-actions</ulink>.
2405 If you prefer plain text editing to GUIs, you can of course also directly edit the
2406 <filename>default.action</filename> file.
2412 <title>How Actions are Applied to URLs</title>
2414 The actions file is divided into sections. There are special sections,
2415 like the alias sections which will be discussed later. For now let's
2416 concentrate on regular sections: They have a heading line (often split
2417 up to multiple lines for readability) which consist of a list of actions,
2418 separated by whitespace and enclosed in curly braces. Below that, there
2419 is a list of URL patterns, each on a separate line.
2423 To determine which actions apply to a request, the URL of the request is
2424 compared to all patterns in this file. Every time it matches, the list of
2425 applicable actions for the URL is incrementally updated, using the heading
2426 of the section in which the pattern is located. If multiple matches for
2427 the same URL set the same action differently, the last match wins.
2431 You can trace this process by visiting <ulink
2432 url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>.
2436 More detail on this is provided in the Appendix, <link linkend="ACTIONSANAT">
2437 Anatomy of an Action</link>.
2441 <!-- ~~~~~ New section ~~~~~ -->
2443 <title>Patterns</title>
2445 Generally, a pattern has the form <literal><domain>/<path></literal>,
2446 where both the <literal><domain></literal> and <literal><path></literal>
2447 are optional. (This is why the pattern <literal>/</literal> matches all URLs).
2452 <term><literal>www.example.com/</literal></term>
2455 is a domain-only pattern and will match any request to <literal>www.example.com</literal>,
2456 regardless of which document on that server is requested.
2461 <term><literal>www.example.com</literal></term>
2464 means exactly the same. For domain-only patterns, the trailing <literal>/</literal> may
2470 <term><literal>www.example.com/index.html</literal></term>
2473 matches only the single document <literal>/index.html</literal>
2474 on <literal>www.example.com</literal>.
2479 <term><literal>/index.html</literal></term>
2482 matches the document <literal>/index.html</literal>, regardless of the domain,
2483 i.e. on <emphasis>any</emphasis> web server.
2488 <term><literal>index.html</literal></term>
2491 matches nothing, since it would be interpreted as a domain name and
2492 there is no top-level domain called <literal>.html</literal>.
2498 <sect4><title>The Domain Pattern</title>
2501 The matching of the domain part offers some flexible options: if the
2502 domain starts or ends with a dot, it becomes unanchored at that end.
2508 <term><literal>.example.com</literal></term>
2511 matches any domain that <emphasis>ENDS</emphasis> in
2512 <literal>.example.com</literal>
2517 <term><literal>www.</literal></term>
2520 matches any domain that <emphasis>STARTS</emphasis> with
2521 <literal>www.</literal>
2526 <term><literal>.example.</literal></term>
2529 matches any domain that <emphasis>CONTAINS</emphasis> <literal>.example.</literal>
2530 (Correctly speaking: It matches any FQDN that contains <literal>example</literal> as a domain.)
2537 Additionally, there are wild-cards that you can use in the domain names
2538 themselves. They work pretty similar to shell wild-cards: <quote>*</quote>
2539 stands for zero or more arbitrary characters, <quote>?</quote> stands for
2540 any single character, you can define character classes in square
2541 brackets and all of that can be freely mixed:
2546 <term><literal>ad*.example.com</literal></term>
2549 matches <quote>adserver.example.com</quote>,
2550 <quote>ads.example.com</quote>, etc but not <quote>sfads.example.com</quote>
2555 <term><literal>*ad*.example.com</literal></term>
2558 matches all of the above, and then some.
2563 <term><literal>.?pix.com</literal></term>
2566 matches <literal>www.ipix.com</literal>,
2567 <literal>pictures.epix.com</literal>, <literal>a.b.c.d.e.upix.com</literal> etc.
2572 <term><literal>www[1-9a-ez].example.c*</literal></term>
2575 matches <literal>www1.example.com</literal>,
2576 <literal>www4.example.cc</literal>, <literal>wwwd.example.cy</literal>,
2577 <literal>wwwz.example.com</literal> etc., but <emphasis>not</emphasis>
2578 <literal>wwww.example.com</literal>.
2586 <sect4><title>The Path Pattern</title>
2589 <application>Privoxy</application> uses Perl compatible regular expressions
2590 (through the <ulink url="http://www.pcre.org/">PCRE</ulink> library) for
2595 There is an <link linkend="regex">Appendix</link> with a brief quick-start into regular
2596 expressions, and full (very technical) documentation on PCRE regex syntax is available on-line
2597 at <ulink url="http://www.pcre.org/man.txt">http://www.pcre.org/man.txt</ulink>.
2598 You might also find the Perl man page on regular expressions (<literal>man perlre</literal>)
2599 useful, which is available on-line at <ulink
2600 url="http://www.perldoc.com/perl5.6/pod/perlre.html">http://www.perldoc.com/perl5.6/pod/perlre.html</ulink>.
2604 Note that the path pattern is automatically left-anchored at the <quote>/</quote>,
2605 i.e. it matches as if it would start with a <quote>^</quote>.
2609 Please also note that matching in the path is case
2610 <emphasis>INSENSITIVE</emphasis> by default, but you can switch to case
2611 sensitive at any point in the pattern by using the
2612 <quote>(?-i)</quote> switch:
2613 <literal>www.example.com/(?-i)PaTtErN.*</literal> will match only
2614 documents whose path starts with <literal>PaTtErN</literal> in
2615 <emphasis>exactly</emphasis> this capitalization.

2626 <sect3 id="actions">
2627 <title>Actions</title>
2629 Actions are enabled if preceded with a <quote>+</quote>, and disabled if
2630 preceded with a <quote>-</quote>. Actions are invoked by enclosing the
2631 action name in curly braces (e.g. {+some_action}), followed by a list of
2632 URLs (or patterns that match URLs) to which the action applies. There are
2633 three classes of actions:
2641 Boolean, i.e the action can only be <quote>on</quote> or
2642 <quote>off</quote>. Examples:
2648 <emphasis>{+name}</emphasis> # enable this action
2649 <emphasis>{-name}</emphasis> # disable this action
2659 Parameterized, e.g. <quote>+/-hide-user-agent{ Mozilla 1.0 }</quote>,
2660 where some value is required in order to enable this type of action.
2667 <emphasis>{+name{param}}</emphasis> # enable action and set parameter to <quote>param</quote>
2668 <emphasis>{-name}</emphasis> # disable action (<quote>parameter</quote>) can be omitted
2677 <!-- oes, or someone, check this. Re-worded 04/20/02 HB. -->
2678 Multi-value, e.g. <quote>{+/-add-header{Name: value}}</quote> ot
2679 <quote>{+/-wafer{name=value}}</quote>), where some value needs to be defined
2680 in addition to simply enabling the actino. Examples:
2686 <emphasis>{+name{param=value}}</emphasis> # enable action and set <quote>param</quote> to <quote>value</quote>
2687 <emphasis>{-name{param=value}}</emphasis> # remove the parameter <quote>param</quote> completely
2688 <emphasis>{-name}</emphasis> # disable this action totally and remove <application>param</application> too
2699 If nothing is specified in this file, no <quote>actions</quote> are taken.
2700 So in this case <application>Privoxy</application> would just be a
2701 normal, non-blocking, non-anonymizing proxy. You must specifically
2702 enable the privacy and blocking features you need (although the
2703 provided default <filename>default.action</filename> file will
2704 give a good starting point).
2708 Later defined actions always over-ride earlier ones. So exceptions
2709 to any rules you make, should come in the latter part of the file. For
2710 multi-valued actions, the actions are applied in the order they are
2714 <!-- start actions listing -->

2895 is used as the replacement. If <quote>last</quote> is given, the last
2896 frame of the animation is used instead, which probably makes more sense for

3012 Many sites, like yahoo.com, don't just link to other sites. Instead, they
3013 will link to some script on their own server, giving the destination as a
3014 parameter, which will then redirect you to the final target. URLs
3015 resulting from this scheme typically look like:
3016 <emphasis>http://some.place/some_script?http://some.where-else</emphasis>.
3019 Sometimes, there are even multiple consecutive redirects encoded in the
3020 URL. These redirections via scripts make your web browsing more traceable,
3021 since the server from which you follow such a link can see where you go
3022 to. Apart from that, valuable bandwidth and time is wasted, while your
3023 browser ask the server for one redirect after the other. Plus, it feeds

3147 Filtering requires buffering the page content, which may appear to
3148 slow down page rendering since nothing is displayed until all content has
3149 passed the filters. (It does not really take longer, but seems that way
3150 since the page is not incrementally displayed.) This effect will be more
3151 noticeable on slower connections.

3572 The CONNECT methods exists in HTTP to allow access to secure websites
3573 (https:// URLs) through proxies. It works very simply: the proxy connects
3574 to the server on the specified port, and then short-circuits its
3575 connections to the client <emphasis>and</emphasis> to the remote proxy.
3576 This can be a big security hole, since CONNECT-enabled proxies can be
3577 abused as TCP relays very easily.
3580 If you want to allow CONNECT for more ports than this, or want to forbid
3581 CONNECT altogether, you can specify a comma separated list of ports and

4168 as <quote>aliases</quote>, can be defined by combining other <quote>actions</quote>.
4169 These can in turn be invoked just like the built-in <quote>actions</quote>.
4170 Currently, an alias can contain any character except space, tab, <quote>=</quote>,
4171 <quote>{</quote> or <quote>}</quote>. But please use only <quote>a</quote>-
4172 <quote>z</quote>, <quote>0</quote>-<quote>9</quote>, <quote>+</quote>, and
4173 <quote>-</quote>. Alias names are not case sensitive, and
4174 <emphasis>must be defined before anything</emphasis> else in the
4175 <filename>default.action</filename>file! And there can only be one set of
4176 <quote>aliases</quote> defined.
4180 Now let's define a few aliases:
4187 # Useful custom aliases we can use later. These must come first!
4189 +no-cookies = +no-cookies-set +no-cookies-read
4190 -no-cookies = -no-cookies-set -no-cookies-read
4191 fragile = -block -no-cookies -filter -fast-redirects -hide-referer -no-popups

4195 #For people who don't like to type too much: ;-)
4198 c2 = -no-cookies-set +no-cookies-read
4199 c3 = +no-cookies-set -no-cookies-read

4252 <sect2 id="filterfile">
4253 <title>The Filter File</title>
4255 Any web page can be dynamically modified with the filter file. This
4256 modification can be removal, or re-writing, of any web page content,
4257 including tags and non-visible content. The default filter file is
4258 <filename>default.filter</filename>, located in the config directory.
4262 This is potentially a very powerful feature, and requires knowledge of both
4263 <quote>regular expression</quote> and HTML in order create custom
4264 filters. But, there are a number of useful filters included with
4265 <application>Privoxy</application> for many common situations.
4269 The included example file is divided into sections. Each section begins
4270 with the <literal>FILTER</literal> keyword, followed by the identifier
4271 for that section, e.g. <quote>FILTER: webbugs</quote>. Each section performs
4272 a similar type of filtering, such as <quote>html-annoyances</quote>.
4276 This file uses regular expressions to alter or remove any string in the
4277 target page. The expressions can only operate on one line at a time. Some
4278 examples from the included default <filename>default.filter</filename>:
4282 Stop web pages from displaying annoying messages in the status bar by
4283 deleting such references:
4290 FILTER: html-annoyances
4292 # New browser windows should be resizeable and have a location and status
4295 s/resizable="?(no|0)"?/resizable=1/ig s/noresize/yesresize/ig
4296 s/location="?(no|0)"?/location=1/ig s/status="?(no|0)"?/status=1/ig
4297 s/scrolling="?(no|0|Auto)"?/scrolling=1/ig
4298 s/menubar="?(no|0)"?/menubar=1/ig
4300 # The <BLINK> tag was a crime!
4302 s*<blink>|</blink>**ig
4306 #s/framespacing="?(no|0)"?//ig
4307 #s/margin(height|width)=[0-9]*//gi

4365 <filename>/etc/privoxy/templates</filename> by default. These may be
4366 customized, if desired. <filename>cgi-style.css</filename> is
4367 used to control the HTML attributes (fonts, etc).
4370 The default <quote>Blocked</quote> banner page with the bright red top
4371 banner, is called just <quote><filename>blocked</filename></quote>. This
4372 may be customized or replaced with something else if desired.

4462 <title>Regular Expressions</title>
4464 <application>Privoxy</application> can use <quote>regular expressions</quote>
4465 in various config files. Assuming support for <quote>pcre</quote> (Perl
4466 Compatible Regular Expressions) is compiled in, which is the default. Such
4467 configuration directives do not require regular expressions, but they can be
4468 used to increase flexibility by matching a pattern with wild-cards against
4473 If you are reading this, you probably don't understand what <quote>regular
4474 expressions</quote> are, or what they can do. So this will be a very brief
4475 introduction only. A full explanation would require a book ;-)
4479 <quote>Regular expressions</quote> is a way of matching one character
4480 expression against another to see if it matches or not. One of the
4481 <quote>expressions</quote> is a literal string of readable characters
4482 (letter, numbers, etc), and the other is a complex string of literal
4483 characters combined with wild-cards, and other special characters, called
4484 meta-characters. The <quote>meta-characters</quote> have special meanings and
4485 are used to build the complex pattern to be matched against. Perl Compatible
4486 Regular Expressions is an enhanced form of the regular expression language
4487 with backward compatibility.
4491 To make a simple analogy, we do something similar when we use wild-card
4492 characters when listing files with the <command>dir</command> command in DOS.
4493 <literal>*.*</literal> matches all filenames. The <quote>special</quote>
4494 character here is the asterisk which matches any and all characters. We can be
4495 more specific and use <literal>?</literal> to match just individual
4496 characters. So <quote>dir file?.text</quote> would match
4497 <quote>file1.txt</quote>, <quote>file2.txt</quote>, etc. We are pattern
4498 matching, using a similar technique to <quote>regular expressions</quote>!
4502 Regular expressions do essentially the same thing, but are much, much more
4503 powerful. There are many more <quote>special characters</quote> and ways of
4504 building complex patterns however. Let's look at a few of the common ones,
4505 and then some examples:
4510 <emphasis>.</emphasis> - Matches any single character, e.g. <quote>a</quote>,
4511 <quote>A</quote>, <quote>4</quote>, <quote>:</quote>, or <quote>@</quote>.
4513 </simplelist></para>
4517 <emphasis>?</emphasis> - The preceding character or expression is matched ZERO or ONE
4520 </simplelist></para>
4524 <emphasis>+</emphasis> - The preceding character or expression is matched ONE or MORE
4527 </simplelist></para>
4531 <emphasis>*</emphasis> - The preceding character or expression is matched ZERO or MORE
4534 </simplelist></para>
4538 <emphasis>\</emphasis> - The <quote>escape</quote> character denotes that
4539 the following character should be taken literally. This is used where one of the
4540 special characters (e.g. <quote>.</quote>) needs to be taken literally and
4541 not as a special meta-character. Example: <quote>example\.com</quote>, makes
4542 sure the period is recognized only as a period (and not expanded to its
4543 metacharacter meaning of any single character).
4545 </simplelist></para>
4549 <emphasis>[]</emphasis> - Characters enclosed in brackets will be matched if
4550 any of the enclosed characters are encountered. For instance, <quote>[0-9]</quote>
4551 matches any numeric digit (zero through nine). As an example, we can combine
4552 this with <quote>+</quote> to match any digit one of more times: <quote>[0-9]+</quote>.
4554 </simplelist></para>
4558 <emphasis>()</emphasis> - parentheses are used to group a sub-expression,
4559 or multiple sub-expressions.
4561 </simplelist></para>
4565 <emphasis>|</emphasis> - The <quote>bar</quote> character works like an
4566 <quote>or</quote> conditional statement. A match is successful if the
4567 sub-expression on either side of <quote>|</quote> matches. As an example:
4568 <quote>/(this|that) example/</quote> uses grouping and the bar character
4569 and would match either <quote>this example</quote> or <quote>that
4570 example</quote>, and nothing else.
4572 </simplelist></para>
4576 <emphasis>s/string1/string2/g</emphasis> - This is used to rewrite strings of text.
4577 <quote>string1</quote> is replaced by <quote>string2</quote> in this
4578 example. There must of course be a match on <quote>string1</quote> first.
4580 </simplelist></para>
4583 These are just some of the ones you are likely to use when matching URLs with
4584 <application>Privoxy</application>, and is a long way from a definitive
4585 list. This is enough to get us started with a few simple examples which may
4586 be more illuminating:
4590 <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
4591 that uses the common combination of <quote>.</quote> and <quote>*</quote> to
4592 denote any character, zero or more times. In other words, any string at all.
4593 So we start with a literal forward slash, then our regular expression pattern
4594 (<quote>.*</quote>) another literal forward slash, the string
4595 <quote>banners</quote>, another forward slash, and lastly another
4596 <quote>.*</quote>. We are building
4597 a directory path here. This will match any file with the path that has a
4598 directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
4599 any characters, and this could conceivably be more forward slashes, so it
4600 might expand into a much longer looking path. For example, this could match:
4601 <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
4602 <quote>/banners/annoying.html</quote>, or almost an infinite number of other
4603 possible combinations, just so it has <quote>banners</quote> in the path
4608 A now something a little more complex:
4612 <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
4613 We have several literal forward slashes again (<quote>/</quote>), so we are
4614 building another expression that is a file path statement. We have another
4615 <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
4616 it matches our expression. The only true literal that <emphasis>must
4617 match</emphasis> our pattern is <application>adv</application>, together with
4618 the forward slashes. What comes after the <quote>adv</quote> string is the
4623 Remember the <quote>?</quote> means the preceding expression (either a
4624 literal character or anything grouped with <quote>(...)</quote> in this case)
4625 can exist or not, since this means either zero or one match. So
4626 <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
4627 individual sub-expressions: <quote>(er)</quote>,
4628 <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
4629 means <quote>or</quote>. We have two of those. For instance,
4630 <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
4631 <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
4632 attempt at matching as many variations of <quote>advertisement</quote>, and
4633 similar, as possible. So this would expand to match just <quote>adv</quote>,
4634 or <quote>advert</quote>, or <quote>adverts</quote>, or
4635 <quote>advertising</quote>, or <quote>advertisement</quote>, or
4636 <quote>advertisements</quote>. You get the idea. But it would not match
4637 <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
4638 changing our regular expression to:
4639 <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
4644 <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
4645 another path statement with forward slashes. Anything in the square brackets
4646 <quote>[]</quote> can be matched. This is using <quote>0-9</quote> as a
4647 shorthand expression to mean any digit one through nine. It is the same as
4648 saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
4649 means one or more of the preceding expression must be included. The preceding
4650 expression here is what is in the square brackets -- in this case, any digit
4651 one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
4652 This includes a <quote>|</quote>, so this needs to match the expression on
4653 either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
4654 side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
4655 since the <quote>?</quote> means the letter <quote>e</quote> is optional and
4656 can be matched once or not at all. So we are building an expression here to
4657 match image GIF or JPEG type image file. It must include the literal
4658 string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
4659 (which is now a literal, and not a special character, since it is escaped
4660 with <quote>\</quote>), and lastly either <quote>gif</quote>, or
4661 <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
4662 include: <quote>//advert1.jpg</quote>,
4663 <quote>/nasty/ads/advert1234.gif</quote>,
4664 <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
4665 <quote>advert1.gif</quote> (no leading slash), or
4666 <quote>/adverts232.jpg</quote> (the expression does not include an
4667 <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
4668 in the expression anywhere).
4672 <emphasis><literal>s/microsoft(?!.com)/MicroSuck/i</literal></emphasis> - This is
4673 a substitution. <quote>MicroSuck</quote> will replace any occurrence of
4674 <quote>microsoft</quote>. The <quote>i</quote> at the end of the expression
4675 means ignore case. The <quote>(?!.com)</quote> means
4676 the match should fail if <quote>microsoft</quote> is followed by
4677 <quote>.com</quote>. In other words, this acts like a <quote>NOT</quote>
4678 modifier. In case this is a hyperlink, we don't want to break it ;-).
4682 We are barely scratching the surface of regular expressions here so that you
4683 can understand the default <application>Privoxy</application>
4684 configuration files, and maybe use this knowledge to customize your own
4685 installation. There is much, much more that can be done with regular
4686 expressions. Now that you know enough to get started, you can learn more on

4708 <application>Privoxy</application>, and see how it is

4902 <title>Anatomy of an Action</title>
4905 The way <application>Privoxy</application> applies <quote>actions</quote>
4906 and <quote>filters</quote> to any given URL can be complex, and not always so
4907 easy to understand what is happening. And sometimes we need to be able to
4908 <emphasis>see</emphasis> just what <application>Privoxy</application> is
4909 doing. Especially, if something <application>Privoxy</application> is doing
4910 is causing us a problem inadvertently. It can be a little daunting to look at
4911 the actions and filters files themselves, since they tend to be filled with
4912 <quote>regular expressions</quote> whose consequences are not always
4917 One quick test to see if <application>Privoxy</application> is causing a problem
4918 or not, is to disable it temporarily. This should be the first troubleshooting
4919 step. See <link linkend="bookmarklets">the Bookmarklets</link> section on a quick
4920 and easy way to do this.
4924 <application>Privoxy</application> also provides the
4925 <ulink url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>
4926 page that can show us very specifically how <application>actions</application>
4927 are being applied to any given URL. This is a big help for troubleshooting.
4931 First, enter one URL (or partial URL) at the prompt, and then
4932 <application>Privoxy</application> will tell us
4933 how the current configuration will handle it. This will not
4934 help with filtering effects from the <filename>default.filter</filename> file! It
4935 also will not tell you about any other URLs that may be embedded within the
4936 URL you are testing (i.e. a web page). For instance, images such as ads are expressed as URLs
4937 within the raw page source of HTML pages. So you will only get info for the
4938 actual URL that is pasted into the prompt area -- not any sub-URLs. If you
4939 want to know about embedded URLs like ads, you will have to dig those out of
4940 the HTML source. Use your browser's <quote>View Page Source</quote> option
4941 for this. Or right click on the ad, and grab the URL.
4945 Let's look at an example, <ulink url="http://google.com">google.com</ulink>,
4946 one section at a time:
4951 System default actions:
4953 { -add-header -block -deanimate-gifs -downgrade -fast-redirects -filter
4954 -hide-forwarded -hide-from -hide-referer -hide-user-agent -image
4955 -image-blocker -limit-connect -no-compression -no-cookies-keep
4956 -no-cookies-read -no-cookies-set -no-popups -vanilla-wafer -wafer }
4962 This is the top section, and only tells us of the compiled in defaults. This
4963 is basically what <application>Privoxy</application> would do if there
4964 were not any <quote>actions</quote> defined, i.e. it does nothing. Every action
4965 is disabled. This is not particularly informative for our purposes here. OK,
4972 Matches for http://google.com:
4974 { -add-header -block +deanimate-gifs -downgrade +fast-redirects
4975 +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
4976 +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}
4977 +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge}
4978 -hide-user-agent -image +image-blocker{blank} +no-compression
4979 +no-cookies-keep -no-cookies-read -no-cookies-set +no-popups
4980 -vanilla-wafer -wafer }
4983 { -no-cookies-keep -no-cookies-read -no-cookies-set }
4993 This is much more informative, and tells us how we have defined our
4994 <quote>actions</quote>, and which ones match for our example,
4995 <quote>google.com</quote>. The first grouping shows our default
4996 settings, which would apply to all URLs. If you look at your <quote>actions</quote>
4997 file, this would be the section just below the <quote>aliases</quote> section
4998 near the top. This applies to all URLs as signified by the single forward
4999 slash -- <quote>/</quote>.
5004 These are the default actions we have enabled. But we can define additional
5005 actions that would be exceptions to these general rules, and then list
5006 specific URLs that these exceptions would apply to. Last match wins.
5007 Just below this then are two explicit matches for <quote>.google.com</quote>.
5008 The first is negating our various cookie blocking actions (i.e. we will allow
5009 cookies here). The second is allowing <quote>fast-redirects</quote>. Note
5010 that there is a leading dot here -- <quote>.google.com</quote>. This will
5011 match any hosts and sub-domains, in the google.com domain also, such as
5012 <quote>www.google.com</quote>. So, apparently, we have these actions defined
5013 somewhere in the lower part of our actions file, and
5014 <quote>google.com</quote> is referenced in these sections.
5019 And now we pull it altogether in the bottom section and summarize how
5020 <application>Privoxy</application> is applying all its <quote>actions</quote>
5021 to <quote>google.com</quote>:
5030 -add-header -block -deanimate-gifs -downgrade -fast-redirects
5031 +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
5032 +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}
5033 +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge}
5034 -hide-user-agent -image +image-blocker{blank} -limit-connect +no-compression
5035 -no-cookies-keep -no-cookies-read -no-cookies-set +no-popups -vanilla-wafer
5042 Now another example, <quote>ad.doubleclick.net</quote>:
5061 We'll just show the interesting part here, the explicit matches. It is
5062 matched three different times. Each as an <quote>+block +image</quote>,
5063 which is the expanded form of one of our aliases that had been defined as:
5064 <quote>+imageblock</quote>. (<quote>Aliases</quote> are defined in the
5065 first section of the actions file and typically used to combine more
5070 Any one of these would have done the trick and blocked this as an unwanted
5071 image. This is unnecessarily redundant since the last case effectively
5072 would also cover the first. No point in taking chances with these guys
5073 though ;-) Note that if you want an ad or obnoxious
5074 URL to be invisible, it should be defined as <quote>ad.doubleclick.net</quote>
5075 is done here -- as both a <quote>+block</quote> <emphasis>and</emphasis> an
5076 <quote>+image</quote>. The custom alias <quote>+imageblock</quote> does this
5081 One last example. Let's try <quote>http://www.rhapsodyk.net/adsl/HOWTO/</quote>.
5082 This one is giving us problems. We are getting a blank page. Hmmm...
5088 Matches for http://www.rhapsodyk.net/adsl/HOWTO/:
5090 { -add-header -block +deanimate-gifs -downgrade +fast-redirects

5106 Ooops, the <quote>/adsl/</quote> is matching <quote>/ads</quote>! But
5107 we did not want this at all! Now we see why we get the blank page. We could
5108 now add a new action below this that explicitly does <emphasis>not</emphasis>
5109 block (-block) pages with <quote>adsl</quote>. There are various ways to
5110 handle such exceptions. Example:
5123 Now the page displays ;-) Be sure to flush your browser's caches when
5124 making such changes. Or, try using <literal>Shift+Reload</literal>.
5128 But now what about a situation where we get no explicit matches like
5142 That actually was very telling and pointed us quickly to where the problem
5143 was. If you don't get this kind of match, then it means one of the default
5144 rules in the first section is causing the problem. This would require some
5145 guesswork, and maybe a little trial and error to isolate the offending rule.
5146 One likely cause would be one of the <quote>{+filter}</quote> actions. Try
5147 adding the URL for the site to one of aliases that turn off <quote>+filter</quote>:
5155 .worldpay.com # for quietpc.com
5164 <quote>{shop}</quote> is an <quote>alias</quote> that expands to
5165 <quote>{ -filter -no-cookies -no-cookies-keep }</quote>. Or you could do
5166 your own exception to negate filtering:
5180 <quote>{fragile}</quote> is an alias that disables most actions. This can be
5181 used as a last resort for problem sites. Remember to flush caches! If this
5182 still does not work, you will have to go through the remaining actions one by
5183 one to find which one(s) is causing the problem.
