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

172 Note: If you have a previous <application>Junkbuster</application> or
173 <application>Privoxy</application> installation on your system, you
174 will either need to remove it, or that might be done by the setup
175 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> In that case, also see the
181 <link linkend="upgradersnote">note to upgraders</link>.
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>
201 automatically, before installing <application>Privoxy</application>.

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

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

1045 think it should block) but in most cases you probably will never look at it.
1048 Your logfile will grow indefinitely, and you will probably want to
1049 periodically remove it. On Unix systems, you can do this with a cron job
1050 (see <quote>man cron</quote>). For Red Hat, a <command>logrotate</command>

1054 On SuSE Linux systems, you can place a line like <quote>/var/log/privoxy.*
1055 +1024k 644 nobody.nogroup</quote> in <filename>/etc/logfiles</filename>, with

1141 The trust mechanism is an experimental feature for building white-lists and should

1145 If you specify a trust file, <application>Privoxy</application> will only allow
1146 access to sites that are named in the trustfile.
1147 You can also mark sites as trusted referrers (with <literal>+</literal>), with
1148 the effect that access to untrusted sites will be granted, if a link from a
1149 trusted referrer was used.
1150 The link target will then be added to the <quote>trustfile</quote>.
1151 Possible applications include limiting Internet access for children.

1217 If you use the trust mechanism, it is a good idea to write up some on-line
1218 documentation about your trust policy and to specify the URL(s) here.
1219 Use multiple times for multiple URLs.
1222 The URL(s) should be added to the trustfile as well, so users don't end up

1392 To select multiple debug levels, you can either add them or use
1393 multiple <literal>debug</literal> lines.
1396 A debug level of 1 is informative because it will show you each request
1397 as it happens. <emphasis>1, 4096 and 8192 are highly recommended</emphasis>
1398 so that you will notice when things go wrong. The other levels are probably
1399 only of interest if you are hunting down a specific problem. They can produce

1749 Access controls are included at the request of ISPs and systems
1750 administrators, and <emphasis>are not usually needed by individual users</emphasis>.
1751 For a typical home user, it will normally suffice to ensure that
1752 <application>Privoxy</application> only listens on the localhost or internal (home)
1753 network address by means of the <literal>listen-address</literal> option.
1756 Please see the warnings in the FAQ that this proxy is not intended to be a substitute
1757 for a firewall or to encourage anyone to defer addressing basic security
1761 Multiple ACL lines are OK.
1762 If any ACLs are specified, then the <application>Privoxy</application>
1763 talks only to IP addresses that match at least one <literal>permit-access</literal> line
1764 and don't match any subsequent <literal>deny-access</literal> line. In other words, the
1765 last match wins, with the default being <literal>deny-access</literal>.
1768 If <application>Privoxy</application> is using a forwarder (see <literal>forward</literal> below)
1769 for a particular destination URL, the <replaceable class="parameter">dst_addr</replaceable>
1770 that is examined is the address of the forwarder and <emphasis>NOT</emphasis> the address
1771 of the ultimate target. This is necessary because it may be impossible for the local
1772 <application>Privoxy</application> to determine the IP address of the
1773 ultimate target (that's often what gateways are used for).
1776 You should prefer using IP addresses over DNS names, because the address lookups take
1777 time. All DNS names must resolve! You can <emphasis>not</emphasis> use domain patterns
1778 like <quote>*.org</quote> or partial domain names. If a DNS name resolves to multiple
1779 IP addresses, only the first one is used.
1782 Denying access to particular sites by ACL may have undesired side effects
1783 if the site in question is hosted on a machine which also hosts other sites.
1788 <term>Examples:</term>
1791 Explicitly define the default behavior if no ACL and
1792 <literal>listen-address</literal> are set: <quote>localhost</quote>
1793 is OK. The absence of a <replaceable class="parameter">dst_addr</replaceable> implies that
1794 <emphasis>all</emphasis> destination addresses are OK:
1798 permit-access localhost

1803 nothing but www.example.com:

1869 flushed to the client unfiltered and no further attempt to

2034 Multiple lines are OK, they are checked in sequence, and the last match wins.
2037 The difference between <literal>forward-socks4</literal> and <literal>forward-socks4a</literal>
2038 is that in the SOCKS 4A protocol, the DNS resolution of the target hostname happens on the SOCKS
2039 server, while in SOCKS 4 it happens locally.
2042 If <replaceable class="parameter">http_parent</replaceable> is <quote>.</quote>, then requests are not
2043 forwarded to another HTTP proxy but are made (HTTP-wise) directly to the web servers, albeit through
2049 <term>Examples:</term>
2052 From the company example.com, direct connections are made to all
2053 <quote>internal</quote> domains, but everything outbound goes through
2054 their ISP's proxy by way of example.com's corporate SOCKS 4A gateway to
2059 forward-socks4a .*. socks-gw.example.com:1080 www-cache.example-isp.net:8080
2060 forward .example.com .
2064 A rule that uses a SOCKS 4 gateway for all destinations but no HTTP parent looks like this:
2068 forward-socks4 .*. socks-gw.example.com:1080 .
2076 <sect4><title>Advanced Forwarding Examples</title>
2079 If you have links to multiple ISPs that provide various special content
2080 only to their subscribers, you can configure multiple <application>Privoxies</application>
2081 which have connections to the respective ISPs to act as forwarders to each other, so that
2082 <emphasis>your</emphasis> users can see the internal content of all ISPs.
2086 Assume that host-a has a PPP connection to isp-a.net. And host-b has a PPP connection to
2087 isp-b.net. Both run <application>Privoxy</application>. Their forwarding
2088 configuration can look like this:
2098 forward .isp-b.net host-b:8118
2109 forward .isp-a.net host-a:8118
2114 Now, your users can set their browser's proxy to use either
2115 host-a or host-b and be able to browse the internal content
2116 of both isp-a and isp-b.
2120 If you intend to chain <application>Privoxy</application> and
2121 <application>squid</application> locally, then chain as
2122 <literal>browser -> squid -> privoxy</literal> is the recommended way.
2126 Assuming that <application>Privoxy</application> and <application>squid</application>
2127 run on the same box, your squid configuration could then look like this:
2132 # Define Privoxy as parent proxy (without ICP)
2133 cache_peer 127.0.0.1 parent 8118 7 no-query
2135 # Define ACL for protocol FTP
2138 # Do not forward FTP requests to Privoxy
2139 always_direct allow ftp
2141 # Forward all the rest to Privoxy
2142 never_direct allow all
2147 You would then need to change your browser's proxy settings to <application>squid</application>'s address and port.
2148 Squid normally uses port 3128. If unsure consult <literal>http_port</literal> in <filename>squid.conf</filename>.

2200 If <quote>log-buffer-size</quote> is set to 1, the size of the log buffer,
2201 i.e. the amount of memory used for the log messages displayed in the
2202 console window, will be limited to <quote>log-max-lines</quote> (see below).

2336 <title>The Actions File</title>
2339 The actions file (<filename>default.action</filename>, formerly:
2340 <filename>actionsfile</filename> or <filename>ijb.action</filename>) is used
2341 to define what actions <application>Privoxy</application> takes for which
2342 URLs, and thus determines how ad images, cookies and various other aspects
2343 of HTTP content and transactions are handled on which sites (or even parts
2348 Anything you want can blocked, including ads, banners, or just some obnoxious
2349 URL that you would rather not see. Cookies can be accepted or rejected, or
2350 accepted only during the current browser session (i.e. not written to disk),
2351 content can be modified, JavaScripts tamed, user-tracking fooled, and much more.
2352 See below for a complete list of available actions.
2356 An actions file typically has sections. At the top, <quote>aliases</quote> are
2357 defined (discussed below), then the default set of rules which will apply
2358 universally to all sites and pages. And then below that is generally a lengthy
2359 set of exceptions to the defined universal policies.
2362 <!-- ~~~~~ New section ~~~~~ -->
2364 <title>Finding the Right Mix</title>
2366 Note that some actions like cookie suppression or script disabling may
2367 render some sites unusable, which rely on these techniques to work properly.
2368 Finding the right mix of actions is not easy and certainly a matter of personal
2369 taste. In general, it can be said that the more <quote>aggressive</quote>
2370 your default settings (in the top section of the actions file) are,
2371 the more exceptions for <quote>trusted</quote> sites you will have to
2372 make later. If, for example, you want to kill popup windows per default, you'll
2373 have to make exceptions from that rule for sites that you regularly use
2374 and that require popups for actually useful content, like maybe your bank,
2375 favorite shop, or newspaper.
2379 We have tried to provide you with reasonable rules to start from in the
2380 distribution actions file. But there is no general rule of thumb on these
2381 things. There just are too many variables, and sites are constantly changing.
2382 Sooner or later you will want to change the rules (and read this chapter).
2386 <!-- ~~~~~ New section ~~~~~ -->
2388 <title>How to Edit</title>
2390 The easiest way to edit the <quote>actions</quote> file is with a browser by
2391 using our browser-based editor, which is available at <ulink
2392 url="http://config.privoxy.org/edit-actions">http://config.privoxy.org/edit-actions</ulink>.
2396 If you prefer plain text editing to GUIs, you can of course also directly edit the
2397 <filename>default.action</filename> file.
2403 <title>How Actions are Applied to URLs</title>
2405 The actions file is divided into sections. There are special sections,
2406 like the alias sections which will be discussed later. For now let's
2407 concentrate on regular sections: They have a heading line (often split
2408 up to multiple lines for readability) which consist of a list of actions,
2409 separated by whitespace and enclosed in curly braces. Below that, there
2410 is a list of URL patterns, each on a separate line.
2414 To determine which actions apply to a request, the URL of the request is
2415 compared to all patterns in this file. Every time it matches, the list of
2416 applicable actions for the URL is incrementally updated, using the heading
2417 of the section in which the pattern is located. If multiple matches for
2418 the same URL set the same action differently, the last match wins.
2422 You can trace this process by visiting <ulink
2423 url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>.
2427 More detail on this is provided in the Appendix, <link linkend="ACTIONSANAT">
2428 Anatomy of an Action</link>.
2432 <!-- ~~~~~ New section ~~~~~ -->
2434 <title>Patterns</title>
2436 Generally, a pattern has the form <literal><domain>/<path></literal>,
2437 where both the <literal><domain></literal> and <literal><path></literal>
2438 are optional. (This is why the pattern <literal>/</literal> matches all URLs).
2443 <term><literal>www.example.com/</literal></term>
2446 is a domain-only pattern and will match any request to <literal>www.example.com</literal>,
2447 regardless of which document on that server is requested.
2452 <term><literal>www.example.com</literal></term>
2455 means exactly the same. For domain-only patterns, the trailing <literal>/</literal> may
2461 <term><literal>www.example.com/index.html</literal></term>
2464 matches only the single document <literal>/index.html</literal>
2465 on <literal>www.example.com</literal>.
2470 <term><literal>/index.html</literal></term>
2473 matches the document <literal>/index.html</literal>, regardless of the domain,
2474 i.e. on <emphasis>any</emphasis> web server.
2479 <term><literal>index.html</literal></term>
2482 matches nothing, since it would be interpreted as a domain name and
2483 there is no top-level domain called <literal>.html</literal>.
2489 <sect4><title>The Domain Pattern</title>
2492 The matching of the domain part offers some flexible options: if the
2493 domain starts or ends with a dot, it becomes unanchored at that end.
2499 <term><literal>.example.com</literal></term>
2502 matches any domain that <emphasis>ENDS</emphasis> in
2503 <literal>.example.com</literal>
2508 <term><literal>www.</literal></term>
2511 matches any domain that <emphasis>STARTS</emphasis> with
2512 <literal>www.</literal>
2517 <term><literal>.example.</literal></term>
2520 matches any domain that <emphasis>CONTAINS</emphasis> <literal>.example.</literal>
2521 (Correctly speaking: It matches any FQDN that contains <literal>example</literal> as a domain.)
2528 Additionally, there are wild-cards that you can use in the domain names
2529 themselves. They work pretty similar to shell wild-cards: <quote>*</quote>
2530 stands for zero or more arbitrary characters, <quote>?</quote> stands for
2531 any single character, you can define character classes in square
2532 brackets and all of that can be freely mixed:
2537 <term><literal>ad*.example.com</literal></term>
2540 matches <quote>adserver.example.com</quote>,
2541 <quote>ads.example.com</quote>, etc but not <quote>sfads.example.com</quote>
2546 <term><literal>*ad*.example.com</literal></term>
2549 matches all of the above, and then some.
2554 <term><literal>.?pix.com</literal></term>
2557 matches <literal>www.ipix.com</literal>,
2558 <literal>pictures.epix.com</literal>, <literal>a.b.c.d.e.upix.com</literal> etc.
2563 <term><literal>www[1-9a-ez].example.c*</literal></term>
2566 matches <literal>www1.example.com</literal>,
2567 <literal>www4.example.cc</literal>, <literal>wwwd.example.cy</literal>,
2568 <literal>wwwz.example.com</literal> etc., but <emphasis>not</emphasis>
2569 <literal>wwww.example.com</literal>.
2577 <sect4><title>The Path Pattern</title>
2580 <application>Privoxy</application> uses Perl compatible regular expressions
2581 (through the <ulink url="http://www.pcre.org/">PCRE</ulink> library) for
2586 There is an <link linkend="regex">Appendix</link> with a brief quick-start into regular
2587 expressions, and full (very technical) documentation on PCRE regex syntax is available on-line
2588 at <ulink url="http://www.pcre.org/man.txt">http://www.pcre.org/man.txt</ulink>.
2589 You might also find the Perl man page on regular expressions (<literal>man perlre</literal>)
2590 useful, which is available on-line at <ulink
2591 url="http://www.perldoc.com/perl5.6/pod/perlre.html">http://www.perldoc.com/perl5.6/pod/perlre.html</ulink>.
2595 Note that the path pattern is automatically left-anchored at the <quote>/</quote>,
2596 i.e. it matches as if it would start with a <quote>^</quote>.
2600 Please also note that matching in the path is case
2601 <emphasis>INSENSITIVE</emphasis> by default, but you can switch to case
2602 sensitive at any point in the pattern by using the
2603 <quote>(?-i)</quote> switch:
2604 <literal>www.example.com/(?-i)PaTtErN.*</literal> will match only
2605 documents whose path starts with <literal>PaTtErN</literal> in
2606 <emphasis>exactly</emphasis> this capitalization.

2617 <sect3 id="actions">
2618 <title>Actions</title>
2620 Actions are enabled if preceded with a <quote>+</quote>, and disabled if
2621 preceded with a <quote>-</quote>. Actions are invoked by enclosing the
2622 action name in curly braces (e.g. {+some_action}), followed by a list of
2623 URLs (or patterns that match URLs) to which the action applies. There are
2624 three classes of actions:
2632 Boolean, i.e the action can only be <quote>on</quote> or
2633 <quote>off</quote>. Examples:
2639 <emphasis>{+name}</emphasis> # enable this action
2640 <emphasis>{-name}</emphasis> # disable this action
2650 Parameterized, e.g. <quote>+/-hide-user-agent{ Mozilla 1.0 }</quote>,
2651 where some value is required in order to enable this type of action.
2658 <emphasis>{+name{param}}</emphasis> # enable action and set parameter to <quote>param</quote>
2659 <emphasis>{-name}</emphasis> # disable action (<quote>parameter</quote>) can be omitted
2668 <!-- oes, or someone, check this. Re-worded 04/20/02 HB. -->
2669 Multi-value, e.g. <quote>{+/-add-header{Name: value}}</quote> ot
2670 <quote>{+/-wafer{name=value}}</quote>), where some value needs to be defined
2671 in addition to simply enabling the actino. Examples:
2677 <emphasis>{+name{param=value}}</emphasis> # enable action and set <quote>param</quote> to <quote>value</quote>
2678 <emphasis>{-name{param=value}}</emphasis> # remove the parameter <quote>param</quote> completely
2679 <emphasis>{-name}</emphasis> # disable this action totally and remove <application>param</application> too
2690 If nothing is specified in this file, no <quote>actions</quote> are taken.
2691 So in this case <application>Privoxy</application> would just be a
2692 normal, non-blocking, non-anonymizing proxy. You must specifically
2693 enable the privacy and blocking features you need (although the
2694 provided default <filename>default.action</filename> file will
2695 give a good starting point).
2699 Later defined actions always over-ride earlier ones. So exceptions
2700 to any rules you make, should come in the latter part of the file. For
2701 multi-valued actions, the actions are applied in the order they are
2705 <!-- start actions listing -->

2886 is used as the replacement. If <quote>last</quote> is given, the last
2887 frame of the animation is used instead, which probably makes more sense for

3003 Many sites, like yahoo.com, don't just link to other sites. Instead, they
3004 will link to some script on their own server, giving the destination as a
3005 parameter, which will then redirect you to the final target. URLs
3006 resulting from this scheme typically look like:
3007 <emphasis>http://some.place/some_script?http://some.where-else</emphasis>.
3010 Sometimes, there are even multiple consecutive redirects encoded in the
3011 URL. These redirections via scripts make your web browsing more traceable,
3012 since the server from which you follow such a link can see where you go
3013 to. Apart from that, valuable bandwidth and time is wasted, while your
3014 browser ask the server for one redirect after the other. Plus, it feeds

3563 The CONNECT methods exists in HTTP to allow access to secure websites
3564 (https:// URLs) through proxies. It works very simply: the proxy connects
3565 to the server on the specified port, and then short-circuits its
3566 connections to the client <emphasis>and</emphasis> to the remote proxy.
3567 This can be a big security hole, since CONNECT-enabled proxies can be
3568 abused as TCP relays very easily.
3571 If you want to allow CONNECT for more ports than this, or want to forbid
3572 CONNECT altogether, you can specify a comma separated list of ports and

4159 as <quote>aliases</quote>, can be defined by combining other <quote>actions</quote>.
4160 These can in turn be invoked just like the built-in <quote>actions</quote>.
4161 Currently, an alias can contain any character except space, tab, <quote>=</quote>,
4162 <quote>{</quote> or <quote>}</quote>. But please use only <quote>a</quote>-
4163 <quote>z</quote>, <quote>0</quote>-<quote>9</quote>, <quote>+</quote>, and
4164 <quote>-</quote>. Alias names are not case sensitive, and
4165 <emphasis>must be defined before anything</emphasis> else in the
4166 <filename>default.action</filename>file! And there can only be one set of
4167 <quote>aliases</quote> defined.
4171 Now let's define a few aliases:
4178 # Useful custom aliases we can use later. These must come first!
4180 +no-cookies = +no-cookies-set +no-cookies-read
4181 -no-cookies = -no-cookies-set -no-cookies-read
4182 fragile = -block -no-cookies -filter -fast-redirects -hide-referer -no-popups
4183 shop = -no-cookies -filter -fast-redirects

4186 #For people who don't like to type too much: ;-)
4189 c2 = -no-cookies-set +no-cookies-read
4190 c3 = +no-cookies-set -no-cookies-read

4243 <sect2 id="filterfile">
4244 <title>The Filter File</title>
4246 Any web page can be dynamically modified with the filter file. This
4247 modification can be removal, or re-writing, of any web page content,
4248 including tags and non-visible content. The default filter file is
4249 <filename>default.filter</filename>, located in the config directory.
4253 This is potentially a very powerful feature, and requires knowledge of both
4254 <quote>regular expression</quote> and HTML in order create custom
4255 filters. But, there are a number of useful filters included with
4256 <application>Privoxy</application> for many common situations.
4260 The included example file is divided into sections. Each section begins
4261 with the <literal>FILTER</literal> keyword, followed by the identifier
4262 for that section, e.g. <quote>FILTER: webbugs</quote>. Each section performs
4263 a similar type of filtering, such as <quote>html-annoyances</quote>.
4267 This file uses regular expressions to alter or remove any string in the
4268 target page. The expressions can only operate on one line at a time. Some
4269 examples from the included default <filename>default.filter</filename>:
4273 Stop web pages from displaying annoying messages in the status bar by
4274 deleting such references:
4281 FILTER: html-annoyances
4283 # New browser windows should be resizeable and have a location and status
4286 s/resizable="?(no|0)"?/resizable=1/ig s/noresize/yesresize/ig
4287 s/location="?(no|0)"?/location=1/ig s/status="?(no|0)"?/status=1/ig
4288 s/scrolling="?(no|0|Auto)"?/scrolling=1/ig
4289 s/menubar="?(no|0)"?/menubar=1/ig
4291 # The <BLINK> tag was a crime!
4293 s*<blink>|</blink>**ig
4297 #s/framespacing="?(no|0)"?//ig
4298 #s/margin(height|width)=[0-9]*//gi

4356 <filename>/etc/privoxy/templates</filename> by default. These may be
4357 customized, if desired. <filename>cgi-style.css</filename> is
4358 used to control the HTML attributes (fonts, etc).
4361 The default <quote>Blocked</quote> banner page with the bright red top
4362 banner, is called just <quote><filename>blocked</filename></quote>. This
4363 may be customized or replaced with something else if desired.

4453 <title>Regular Expressions</title>
4455 <application>Privoxy</application> can use <quote>regular expressions</quote>
4456 in various config files. Assuming support for <quote>pcre</quote> (Perl
4457 Compatible Regular Expressions) is compiled in, which is the default. Such
4458 configuration directives do not require regular expressions, but they can be
4459 used to increase flexibility by matching a pattern with wild-cards against
4464 If you are reading this, you probably don't understand what <quote>regular
4465 expressions</quote> are, or what they can do. So this will be a very brief
4466 introduction only. A full explanation would require a book ;-)
4470 <quote>Regular expressions</quote> is a way of matching one character
4471 expression against another to see if it matches or not. One of the
4472 <quote>expressions</quote> is a literal string of readable characters
4473 (letter, numbers, etc), and the other is a complex string of literal
4474 characters combined with wild-cards, and other special characters, called
4475 meta-characters. The <quote>meta-characters</quote> have special meanings and
4476 are used to build the complex pattern to be matched against. Perl Compatible
4477 Regular Expressions is an enhanced form of the regular expression language
4478 with backward compatibility.
4482 To make a simple analogy, we do something similar when we use wild-card
4483 characters when listing files with the <command>dir</command> command in DOS.
4484 <literal>*.*</literal> matches all filenames. The <quote>special</quote>
4485 character here is the asterisk which matches any and all characters. We can be
4486 more specific and use <literal>?</literal> to match just individual
4487 characters. So <quote>dir file?.text</quote> would match
4488 <quote>file1.txt</quote>, <quote>file2.txt</quote>, etc. We are pattern
4489 matching, using a similar technique to <quote>regular expressions</quote>!
4493 Regular expressions do essentially the same thing, but are much, much more
4494 powerful. There are many more <quote>special characters</quote> and ways of
4495 building complex patterns however. Let's look at a few of the common ones,
4496 and then some examples:
4501 <emphasis>.</emphasis> - Matches any single character, e.g. <quote>a</quote>,
4502 <quote>A</quote>, <quote>4</quote>, <quote>:</quote>, or <quote>@</quote>.
4504 </simplelist></para>
4508 <emphasis>?</emphasis> - The preceding character or expression is matched ZERO or ONE
4511 </simplelist></para>
4515 <emphasis>+</emphasis> - The preceding character or expression is matched ONE or MORE
4518 </simplelist></para>
4522 <emphasis>*</emphasis> - The preceding character or expression is matched ZERO or MORE
4525 </simplelist></para>
4529 <emphasis>\</emphasis> - The <quote>escape</quote> character denotes that
4530 the following character should be taken literally. This is used where one of the
4531 special characters (e.g. <quote>.</quote>) needs to be taken literally and
4532 not as a special meta-character. Example: <quote>example\.com</quote>, makes
4533 sure the period is recognized only as a period (and not expanded to its
4534 metacharacter meaning of any single character).
4536 </simplelist></para>
4540 <emphasis>[]</emphasis> - Characters enclosed in brackets will be matched if
4541 any of the enclosed characters are encountered. For instance, <quote>[0-9]</quote>
4542 matches any numeric digit (zero through nine). As an example, we can combine
4543 this with <quote>+</quote> to match any digit one of more times: <quote>[0-9]+</quote>.
4545 </simplelist></para>
4549 <emphasis>()</emphasis> - parentheses are used to group a sub-expression,
4550 or multiple sub-expressions.
4552 </simplelist></para>
4556 <emphasis>|</emphasis> - The <quote>bar</quote> character works like an
4557 <quote>or</quote> conditional statement. A match is successful if the
4558 sub-expression on either side of <quote>|</quote> matches. As an example:
4559 <quote>/(this|that) example/</quote> uses grouping and the bar character
4560 and would match either <quote>this example</quote> or <quote>that
4561 example</quote>, and nothing else.
4563 </simplelist></para>
4567 <emphasis>s/string1/string2/g</emphasis> - This is used to rewrite strings of text.
4568 <quote>string1</quote> is replaced by <quote>string2</quote> in this
4569 example. There must of course be a match on <quote>string1</quote> first.
4571 </simplelist></para>
4574 These are just some of the ones you are likely to use when matching URLs with
4575 <application>Privoxy</application>, and is a long way from a definitive
4576 list. This is enough to get us started with a few simple examples which may
4577 be more illuminating:
4581 <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
4582 that uses the common combination of <quote>.</quote> and <quote>*</quote> to
4583 denote any character, zero or more times. In other words, any string at all.
4584 So we start with a literal forward slash, then our regular expression pattern
4585 (<quote>.*</quote>) another literal forward slash, the string
4586 <quote>banners</quote>, another forward slash, and lastly another
4587 <quote>.*</quote>. We are building
4588 a directory path here. This will match any file with the path that has a
4589 directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
4590 any characters, and this could conceivably be more forward slashes, so it
4591 might expand into a much longer looking path. For example, this could match:
4592 <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
4593 <quote>/banners/annoying.html</quote>, or almost an infinite number of other
4594 possible combinations, just so it has <quote>banners</quote> in the path
4599 A now something a little more complex:
4603 <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
4604 We have several literal forward slashes again (<quote>/</quote>), so we are
4605 building another expression that is a file path statement. We have another
4606 <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
4607 it matches our expression. The only true literal that <emphasis>must
4608 match</emphasis> our pattern is <application>adv</application>, together with
4609 the forward slashes. What comes after the <quote>adv</quote> string is the
4614 Remember the <quote>?</quote> means the preceding expression (either a
4615 literal character or anything grouped with <quote>(...)</quote> in this case)
4616 can exist or not, since this means either zero or one match. So
4617 <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
4618 individual sub-expressions: <quote>(er)</quote>,
4619 <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
4620 means <quote>or</quote>. We have two of those. For instance,
4621 <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
4622 <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
4623 attempt at matching as many variations of <quote>advertisement</quote>, and
4624 similar, as possible. So this would expand to match just <quote>adv</quote>,
4625 or <quote>advert</quote>, or <quote>adverts</quote>, or
4626 <quote>advertising</quote>, or <quote>advertisement</quote>, or
4627 <quote>advertisements</quote>. You get the idea. But it would not match
4628 <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
4629 changing our regular expression to:
4630 <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
4635 <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
4636 another path statement with forward slashes. Anything in the square brackets
4637 <quote>[]</quote> can be matched. This is using <quote>0-9</quote> as a
4638 shorthand expression to mean any digit one through nine. It is the same as
4639 saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
4640 means one or more of the preceding expression must be included. The preceding
4641 expression here is what is in the square brackets -- in this case, any digit
4642 one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
4643 This includes a <quote>|</quote>, so this needs to match the expression on
4644 either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
4645 side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
4646 since the <quote>?</quote> means the letter <quote>e</quote> is optional and
4647 can be matched once or not at all. So we are building an expression here to
4648 match image GIF or JPEG type image file. It must include the literal
4649 string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
4650 (which is now a literal, and not a special character, since it is escaped
4651 with <quote>\</quote>), and lastly either <quote>gif</quote>, or
4652 <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
4653 include: <quote>//advert1.jpg</quote>,
4654 <quote>/nasty/ads/advert1234.gif</quote>,
4655 <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
4656 <quote>advert1.gif</quote> (no leading slash), or
4657 <quote>/adverts232.jpg</quote> (the expression does not include an
4658 <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
4659 in the expression anywhere).
4663 <emphasis><literal>s/microsoft(?!.com)/MicroSuck/i</literal></emphasis> - This is
4664 a substitution. <quote>MicroSuck</quote> will replace any occurrence of
4665 <quote>microsoft</quote>. The <quote>i</quote> at the end of the expression
4666 means ignore case. The <quote>(?!.com)</quote> means
4667 the match should fail if <quote>microsoft</quote> is followed by
4668 <quote>.com</quote>. In other words, this acts like a <quote>NOT</quote>
4669 modifier. In case this is a hyperlink, we don't want to break it ;-).
4673 We are barely scratching the surface of regular expressions here so that you
4674 can understand the default <application>Privoxy</application>
4675 configuration files, and maybe use this knowledge to customize your own
4676 installation. There is much, much more that can be done with regular
4677 expressions. Now that you know enough to get started, you can learn more on

4699 <application>Privoxy</application>, and see how it is

4893 <title>Anatomy of an Action</title>
4896 The way <application>Privoxy</application> applies <quote>actions</quote>
4897 and <quote>filters</quote> to any given URL can be complex, and not always so
4898 easy to understand what is happening. And sometimes we need to be able to
4899 <emphasis>see</emphasis> just what <application>Privoxy</application> is
4900 doing. Especially, if something <application>Privoxy</application> is doing
4901 is causing us a problem inadvertently. It can be a little daunting to look at
4902 the actions and filters files themselves, since they tend to be filled with
4903 <quote>regular expressions</quote> whose consequences are not always
4908 One quick test to see if <application>Privoxy</application> is causing a problem
4909 or not, is to disable it temporarily. This should be the first troubleshooting
4910 step. See <link linkend="bookmarklets">the Bookmarklets</link> section on a quick
4911 and easy way to do this.
4915 <application>Privoxy</application> also provides the
4916 <ulink url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>
4917 page that can show us very specifically how <application>actions</application>
4918 are being applied to any given URL. This is a big help for troubleshooting.
4922 First, enter one URL (or partial URL) at the prompt, and then
4923 <application>Privoxy</application> will tell us
4924 how the current configuration will handle it. This will not
4925 help with filtering effects from the <filename>default.filter</filename> file! It
4926 also will not tell you about any other URLs that may be embedded within the
4927 URL you are testing (i.e. a web page). For instance, images such as ads are expressed as URLs
4928 within the raw page source of HTML pages. So you will only get info for the
4929 actual URL that is pasted into the prompt area -- not any sub-URLs. If you
4930 want to know about embedded URLs like ads, you will have to dig those out of
4931 the HTML source. Use your browser's <quote>View Page Source</quote> option
4932 for this. Or right click on the ad, and grab the URL.
4936 Let's look at an example, <ulink url="http://google.com">google.com</ulink>,
4937 one section at a time:
4942 System default actions:
4944 { -add-header -block -deanimate-gifs -downgrade -fast-redirects -filter
4945 -hide-forwarded -hide-from -hide-referer -hide-user-agent -image
4946 -image-blocker -limit-connect -no-compression -no-cookies-keep
4947 -no-cookies-read -no-cookies-set -no-popups -vanilla-wafer -wafer }
4953 This is the top section, and only tells us of the compiled in defaults. This
4954 is basically what <application>Privoxy</application> would do if there
4955 were not any <quote>actions</quote> defined, i.e. it does nothing. Every action
4956 is disabled. This is not particularly informative for our purposes here. OK,
4963 Matches for http://google.com:
4965 { -add-header -block +deanimate-gifs -downgrade +fast-redirects
4966 +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
4967 +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}
4968 +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge}
4969 -hide-user-agent -image +image-blocker{blank} +no-compression
4970 +no-cookies-keep -no-cookies-read -no-cookies-set +no-popups
4971 -vanilla-wafer -wafer }
4974 { -no-cookies-keep -no-cookies-read -no-cookies-set }
4984 This is much more informative, and tells us how we have defined our
4985 <quote>actions</quote>, and which ones match for our example,
4986 <quote>google.com</quote>. The first grouping shows our default
4987 settings, which would apply to all URLs. If you look at your <quote>actions</quote>
4988 file, this would be the section just below the <quote>aliases</quote> section
4989 near the top. This applies to all URLs as signified by the single forward
4990 slash -- <quote>/</quote>.
4995 These are the default actions we have enabled. But we can define additional
4996 actions that would be exceptions to these general rules, and then list
4997 specific URLs that these exceptions would apply to. Last match wins.
4998 Just below this then are two explicit matches for <quote>.google.com</quote>.
4999 The first is negating our various cookie blocking actions (i.e. we will allow
5000 cookies here). The second is allowing <quote>fast-redirects</quote>. Note
5001 that there is a leading dot here -- <quote>.google.com</quote>. This will
5002 match any hosts and sub-domains, in the google.com domain also, such as
5003 <quote>www.google.com</quote>. So, apparently, we have these actions defined
5004 somewhere in the lower part of our actions file, and
5005 <quote>google.com</quote> is referenced in these sections.
5010 And now we pull it altogether in the bottom section and summarize how
5011 <application>Privoxy</application> is applying all its <quote>actions</quote>
5012 to <quote>google.com</quote>:
5021 -add-header -block -deanimate-gifs -downgrade -fast-redirects
5022 +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
5023 +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}
5024 +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge}
5025 -hide-user-agent -image +image-blocker{blank} -limit-connect +no-compression
5026 -no-cookies-keep -no-cookies-read -no-cookies-set +no-popups -vanilla-wafer
5033 Now another example, <quote>ad.doubleclick.net</quote>:
5052 We'll just show the interesting part here, the explicit matches. It is
5053 matched three different times. Each as an <quote>+block +image</quote>,
5054 which is the expanded form of one of our aliases that had been defined as:
5055 <quote>+imageblock</quote>. (<quote>Aliases</quote> are defined in the
5056 first section of the actions file and typically used to combine more
5061 Any one of these would have done the trick and blocked this as an unwanted
5062 image. This is unnecessarily redundant since the last case effectively
5063 would also cover the first. No point in taking chances with these guys
5064 though ;-) Note that if you want an ad or obnoxious
5065 URL to be invisible, it should be defined as <quote>ad.doubleclick.net</quote>
5066 is done here -- as both a <quote>+block</quote> <emphasis>and</emphasis> an
5067 <quote>+image</quote>. The custom alias <quote>+imageblock</quote> does this
5072 One last example. Let's try <quote>http://www.rhapsodyk.net/adsl/HOWTO/</quote>.
5073 This one is giving us problems. We are getting a blank page. Hmmm...
5079 Matches for http://www.rhapsodyk.net/adsl/HOWTO/:
5081 { -add-header -block +deanimate-gifs -downgrade +fast-redirects
5082 +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
5083 +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}
5084 +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge}
5085 -hide-user-agent -image +image-blocker{blank} +no-compression
5086 +no-cookies-keep -no-cookies-read -no-cookies-set +no-popups
5087 -vanilla-wafer -wafer }
5097 Ooops, the <quote>/adsl/</quote> is matching <quote>/ads</quote>! But
5098 we did not want this at all! Now we see why we get the blank page. We could
5099 now add a new action below this that explicitly does <emphasis>not</emphasis>
5100 block (-block) pages with <quote>adsl</quote>. There are various ways to
5101 handle such exceptions. Example:
5114 Now the page displays ;-) Be sure to flush your browser's caches when
5115 making such changes. Or, try using <literal>Shift+Reload</literal>.
5119 But now what about a situation where we get no explicit matches like
5133 That actually was very telling and pointed us quickly to where the problem
5134 was. If you don't get this kind of match, then it means one of the default
5135 rules in the first section is causing the problem. This would require some
5136 guesswork, and maybe a little trial and error to isolate the offending rule.
5137 One likely cause would be one of the <quote>{+filter}</quote> actions. Try
5138 adding the URL for the site to one of aliases that turn off <quote>+filter</quote>:
5146 .worldpay.com # for quietpc.com
5155 <quote>{shop}</quote> is an <quote>alias</quote> that expands to
5156 <quote>{ -filter -no-cookies -no-cookies-keep }</quote>. Or you could do
5157 your own exception to negate filtering:
5171 <quote>{fragile}</quote> is an alias that disables most actions. This can be
5172 used as a last resort for problem sites. Remember to flush caches! If this
5173 still does not work, you will have to go through the remaining actions one by
5174 one to find which one(s) is causing the problem.
