163 <application>Privoxy</application> is the

172 <application> Junkbuster</application>-derived software under the same name
176 There are also potential legal complications from the continued use of the
177 <application>Junkbuster</application> name, which is a registered trademark of
178 <ulink url="http://junkbusters.com/">Junkbusters Corporation</ulink>.
179 There are, however, no objections from Junkbusters Corporation to the
180 <application>Privoxy</application> project itself, and they, in fact, still
181 share our ideals and goals.
184 The developers also believed that there are so many changes from the original
185 code, that it was time to make a clean break from the past and make
186 a name in their own right<![%p-not-stable;[, especially now with the pending
187 release of version 3.0]]>.
192 <sect2 renderas="sect3" id="differs"><title>How does <application>Privoxy</application> differ
193 from the old <application>Junkbuster?</application></title>
195 <application>Privoxy</application> picks up where
196 <application>Junkbuster</application> left off. All the old features remain.
197 The new <application>Privoxy</application> still blocks ads and banners,
198 still manages cookies, and still helps protect your privacy. But, these are
199 all enhanced, and many new features have been added, all in the same vein.
202 The configuration has changed significantly as well. This is something that
203 users will notice right off the bat if upgrading from
204 <application>Junkbuster</application> 2.0.x. The <quote>blocklist</quote>
205 <quote>cookielist</quote>, <quote>imagelist</quote> and much more has been
206 combined into the <quote>actions</quote> files, with a completely different
207 syntax. See the <ulink url="../user-manual/upgradersnote.html">note to
208 upgraders</ulink> for details.
211 <application>Privoxy</application>'s new features include:

220 <sect2 renderas="sect3" id="proxymoron"><title>What is a <quote>proxy</quote>? How does
221 <application>Privoxy</application> work? </title>
223 A web proxy is a service, based on a software such as <application>Privoxy</application>,
224 that clients (i.e. browsers) can use instead of connecting directly to the web
225 servers on the Internet. The clients then ask the proxy to fetch the objects
226 they need (web pages, images, movies etc) on their behalf, and when the proxy
227 has done so, it hands the results back to the client.
230 There are many reasons to use web proxies, such as security (firewalling),
231 efficiency (caching) and others, and there are just as many different proxies
232 to accommodate those needs.
235 <application>Privoxy</application> is a proxy that is solely focused on privacy
236 protection and junk elimination. Sitting between your browser(s) and the Internet,
237 it is in a perfect position to filter outbound personal information that your
238 browser is leaking, as well as inbound junk. It uses a variety of techniques to do
239 this, all of which are under your control via the various configuration
245 <sect2 renderas="sect3" id="whatsanad">
246 <title id="knows">How does <application>Privoxy</application> know what is
247 an ad, and what is not?</title>
249 <application>Privoxy</application>'s approach to blocking ads is twofold:
252 First, there are certain patterns in the <emphasis>locations</emphasis> (URLs)
253 of banner images. This applies to both the path (you wouldn't guess how many
254 web sites serve their banners from a directory called <quote>banners</quote>!)
255 and the host (blocking the big banner hosting services like doublecklick.net
256 already helps a lot). <application>Privoxy</application> takes advantage of this
257 fact by using <ulink url="../user-manual/actions-file.html#AF-PATTERNS">URL
258 patterns</ulink> to sort out and block the requests for banners.
261 Second, banners tend to come in certain <emphasis>sizes</emphasis>. But you
262 can't tell the size of an image by its URL without downloading it, and if you
263 do, it's too late to save bandwidth. Therefore, <application>Privoxy</application>
264 also inspects the HTML sources of web pages while they are loaded, and replaces
265 references to images with standard banner sizes by dummy references, so that
266 your browser doesn't request them anymore in the first place.
269 Both of this involves a certain amount of guesswork and is, of course, freely
274 <sect2 renderas="sect3">
275 <title id="mistakes">Can <application>Privoxy</application> make mistakes?
276 This does not sound very scientific.</title>
278 Actually, it's a black art ;-) And yes, it is always possible to have a broad
279 rule accidentally block or change something by mistake. There is a good chance
280 you may run into such a situation at some point. It is tricky writing rules to
281 cover every conceivable possibility, and not occasionally get false positives.
285 But this should not be a big concern since the
286 <application>Privoxy</application> configuration is very flexible, and
287 includes tools to help identify these types of situations so they can be
288 addressed as needed, allowing you to customize your installation.
289 (<link linkend="badsite">See the Troubleshooting section below</link>.)
295 <sect2 renderas="sect3" id="browsers2"><title>My browser does the same things as
296 <application>Privoxy</application>. Why should I use
297 <application>Privoxy</application> at all?</title>
299 Modern browsers do indeed have <emphasis>some</emphasis> of the same
300 functionality as <application>Privoxy</application>. Maybe this is
301 adequate for you. But <application>Privoxy</application> is much more
302 versatile and powerful, and can do a number of things that browsers just can't.
305 In addition, a proxy is good choice if you use multiple browsers, or
306 have a LAN with multiple computers. This way all the configuration
307 is in one place, and you don't have to maintain a similar configuration
308 for possibly many browsers.
314 <sect2 renderas="sect3" id="license"><title>Is there is a license or fee? What about a
315 warranty? Registration?</title>
317 <application>Privoxy</application> is licensed under the <ulink

383 Any browser that can be configured to use a proxy, which
384 should be virtually all browsers. Direct browser support is not necessary
385 since <application>Privoxy</application> runs as a separate application and
386 talks to the browser in the standardized HTTP protocol, just like a web server

400 <title>Can I use <application>Privoxy</application> with my email client?</title>
402 As long as there is some way to set a HTTP proxy for the client, then yes,
403 any application can be used, whether it is strictly speaking a
404 <quote>browser</quote> or not. Though this may not be the best approach for
405 dealing with some of the common abuses of HTML in email. See <link

411 Be aware that HTML email presents a number of unique security and privacy
412 related issues, that can require advanced skills to overcome. The developers
413 recommend using email clients that can be configured to convert HTML to plain
414 text for these reasons.
418 <sect2 renderas="sect3" id="newinstall"><title>Can I install
419 <application>Privoxy</application> over <application>Junkbuster</application>?</title>
421 We recommend you un-install <application>Junkbuster</application>
422 first to minimize conflicts and confusion. You may want to
423 save your old configuration files for future reference. The configuration
424 files and syntax have substantially changed, so you will need to manually
425 port your old patterns. See the <ulink url="../user-manual/upgradersnote.html">note
426 to upgraders</ulink> and <ulink url="../user-manual/installation.html">installation
427 chapter</ulink> in the <ulink url="../user-manual/index.html">user manual</ulink>
431 Note: Some installers may automatically un-install
432 <application>Junkbuster</application>, if present!
437 <sect2 renderas="sect3">
438 <title id="firststep">I just installed <application>Privoxy</application>. Is there anything
439 special I have to do now?</title>
442 All browsers must be told to use <application>Privoxy</application>
443 as a proxy by specifying the correct proxy address and port number
444 in the appropriate configuration area for the browser. See below.
445 You should also flush your browser's memory and disk cache to get rid of any
446 cached junk items, and remove any stored cookies.
453 <sect2 renderas="sect3" id="localhost"><title>What is the proxy address of <application>Privoxy</application>?</title>
455 If you set up the <application>Privoxy</application> to run on
456 the computer you browse from (rather than your ISP's server or some
457 networked computer on a LAN), the proxy will be on <literal>127.0.0.1</literal>
458 (sometimes referred to as <quote>localhost</quote>,
459 which is the special name used by every computer on the Internet to refer
460 to itself) and the port will be 8118 (unless you have <application>Privoxy</application>
461 to run on a different port with the <ulink
462 url="../user-manual/config.html#LISTEN-ADDRESS">listen-address</ulink> config option).
465 When configuring your browser's proxy settings you typically enter
466 the word <quote>localhost</quote> or the IP address <quote>127.0.0.1</quote>
467 in the boxes next to <quote>HTTP</quote> and <quote>Secure</quote> (HTTPS) and
468 then the number <quote>8118</quote> for <quote>port</quote>.
469 This tells your browser to send all web requests to <application>Privoxy</application>
470 instead of directly to the Internet.
473 <application>Privoxy</application> can also be used to proxy for
474 a Local Area Network. In this case, your would enter either the IP
475 address of the LAN host where <application>Privoxy</application>
476 is running, or the equivalent hostname. Port assignment would be
477 same as above. Note that <application>Privoxy</application> doesn't
478 listen on any LAN interfaces by default.
481 <application>Privoxy</application> does not currently handle
482 protocols such as FTP, SMTP, IM, IRC, ICQ, or other Internet
487 <sect2 renderas="sect3" id="nothing">
488 <title>I just installed <application>Privoxy</application>, and nothing is happening.
489 All the ads are there. What's wrong?</title>
492 Did you configure your browser to use <application>Privoxy</application>
493 as a proxy? It does not sound like it. See above. You might also try flushing
494 the browser's caches to force a full re-reading of pages. You can verify
495 that <application>Privoxy</application> is running, and your browser
496 is correctly configured by entering the special URL:
497 <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>.
498 This should take you to a page titled <quote>This is Privoxy..</quote> with
499 access to <application>Privoxy's</application> internal configuration.
500 If you see this, then you are good to go. If you receive a page saying
501 <quote>Privoxy is not running</quote>, then the browser is not set up to use
502 your <application>Privoxy</application> installation.
503 If you receive anything else (probably nothing at all), it could either
504 be that the browser is not set up correctly, or that
505 <application>Privoxy</application> is not running at all. Check the <ulink
506 url="../user-manual/config.html#LOGFILE">log file</ulink>.

521 made available on the <ulink

523 our <ulink url="http://sf.net/projects/ijbswa/">project page</ulink>.

535 <sect2 renderas="sect3" id="newconfig"><title>Can I use my old config files?</title>
537 The syntax, number, and purpose of configuration files has substantially
538 changed from <application>Junkbuster</application> and earlier versions
539 of <application>Privoxy</application>. The old files, like <filename>blocklist</filename>
540 will not work at all. If you are upgrading from a 2.0.x version, you will
541 need to port your configuration data to the new format. Note that even the
542 pattern syntax has changed! Even configuration files from the 2.9.x versions
543 will need to be adapted, as configuration syntax has been very much in flow
548 <sect2 renderas="sect3">
549 <title id="actionsfile">What is an <quote>actions</quote> file?</title>
552 <ulink url="../user-manual/actions-file.html">Actions files</ulink>
553 are where various <ulink url="../user-manual/actions-file.html#ACTIONS">actions</ulink>
554 that <application>Privoxy</application> might take while processing a certain
555 request, are configured. Typically, you would define a set of default actions
556 that apply to all URLs, then add exceptions to these defaults where needed.
560 Actions can be defined on a <ulink
561 url="../user-manual/actions-file.html#AF-PATTERNS">URL pattern</ulink> basis, i.e.
562 for single URLs, whole web sites, groups or parts thereof etc. Actions can also be
563 grouped together and then applied to requests matching one or more patterns.
564 There are many possible actions that might apply to any given site. As an example,
565 if you are blocking cookies as one of your default actions, but need to accept
566 cookies from a given site, you would need to define an exception for this
567 site in one of your actions files, preferably in <filename>user.action</filename>.

604 <title>There are several different <quote>actions</quote> files. What are
605 the differences?</title>
607 As of <application>Privoxy</application> v2.9.15, three actions files
608 are being included, to be used for
609 different purposes: These are
610 <filename>default.action</filename>, the <quote>main</quote> actions file
611 which is actively maintained by the <application>Privoxy</application>
612 developers, <filename>user.action</filename>, where users are encouraged

614 which is for internal <application>Privoxy</application> use only.
615 Please see <ulink url="../user-manual/actions-file.html">the actions chapter</ulink>
616 in the <ulink url="../user-manual/index.html">user manual</ulink> for a more
617 detailed explanation.
621 Earlier versions included three different versions of the
622 <filename>default.action</filename> file. The new scheme allows for
623 greater flexibility of local configuration, and for browser based
624 selection of pre-defined <quote>aggressiveness</quote> levels.
629 <sect2 renderas="sect3" id="yahoo"><title>How can I make my Yahoo/Hotmail/GMX account work?</title>
631 The default configuration shouldn't impact the usability of any of these services.
632 It will, however, make all cookies temporary, so that your browser will forget your
633 login credentials in between browser sessions. If you would like not to have to log
634 in manually each time you access those websites, simply turn off all cookie handling
635 for them in the <filename>user.action</filename> file. An example for yahoo might

678 with a browser? Does that not raise security issues?</title>
680 It may seem strange that regular users can edit the config files with their
681 browsers, although the whole <filename>/etc/privoxy</filename> hierarchy
682 belongs to the user <quote>privoxy</quote>, with only 644 permissions.
685 When you use the browser-based editor, <application>Privoxy</application>
686 itself is writing to the config files. Because
687 <application>Privoxy</application> is running as the user <quote>privoxy</quote>,
688 it can update the config files.
691 If you run <application>Privoxy</application> for multiple untrusted users (e.g. in
692 a LAN), you will probably want to turn the web-based editor and remote toggle
693 features off by setting <quote><literal><ulink
694 url="../user-manual/config.html#ENABLE-EDIT-ACTIONS">enable-edit-actions</ulink>
695 0</literal></quote> and <quote><literal><ulink

700 Note that in the default configuration, only local users (i.e. those on

712 remove, web page content on the fly. Filters apply to <emphasis>anything</emphasis>
713 in the page source, including HTML tags, and JavaScript. Regular expressions are used
714 to accomplish this. There are a number of pre-defined filters to deal with common
715 annoyances. The filters are only defined here, to invoke them, you need to use the
717 url="../user-manual/actions-file.html#FILTER"><literal>filter</literal>

719 disabled for inappropriate MIME types.
723 If you are familiar with regular expressions, and HTML, you can look at
724 the provided <filename>default.filter</filename> with a text editor and define
725 your own filters. This is potentially a very powerful feature, but
726 requires some expertise in both regular expressions and HTML/HTTP.
730 Presently, there is no GUI editor option for this part of the configuration,

841 These are URLs that match something in one of
842 <application>Privoxy's</application> block actions
844 url="../user-manual/actions-file.html#BLOCK"><quote>+block</quote></ulink>).
845 It is meant to be a warning so that you know something has been blocked and
846 an easy way for you to see why. These are handled differently than what has
847 been defined explicitly as <quote>images</quote> (e.g. ads that are GIF image
848 files). Depending on the URL itself, it is sometimes hard for
849 <application>Privoxy</application> to really know whether there is indeed an
850 ad image there or not. And there are limitations as to what
851 <application>Privoxy</application> can do to <quote>fool</quote> the
856 For instance, if the ad is in a frame, then it is embedded in the separate
857 HTML page used for the frame. In this case, you cannot just substitute an
858 aribitrary image (like we would for a <quote>blank</quote> image), for an HTML
859 page. The browser is expecting an HTML page, and that is what it must have
860 for frames. Such situations can be a little trickier to deal with, and
861 <application>Privoxy</application> may show the <quote>Blocked</quote> page,
862 despite your best efforts.
866 If you want these to be treated as if they were images, so that they can be
867 made invisible, you can try moving the offending URL from the
868 <quote>+block</quote> section to the <quote>+imageblock</quote> section of
869 your actions file. Just be forewarned, if any URL is made
870 <quote>invisible</quote>, you may not have any inkling that something has
871 been removed from that page, or why. If this approach does not work, then you are
872 probably dealing with a frame (or <quote>ilayer</quote>), and the only thing
873 that can go there is an HTML page of some sort.
876 To deal with this situation, you could modify the
877 <quote><filename>block</filename></quote> HTML template that is used by
878 <application>Privoxy</application> to display this, and make it something
879 more to your liking. Currently, there is no configuration option for this.
880 You will have to modify, or create your own page, and use this to replace
881 <filename>templates/blocked</filename>, which is what
882 <application>Privoxy</application> uses to display the <quote>Blocked</quote>
886 Another way to deal with this is find why and where
887 <application>Privoxy</application> is blocking the frame, and
888 diable this. Then let the <quote>+set-image-blocker</quote> action
889 handle the ad that is embedded in the frame's HTML page.

904 As of Privoxy 2.9.14, the Blocked banner page is re-sizeable, and tries

914 <title id="blockedbytext">I see some images being replaced by a text

917 This happens when the banners are not embedded in the HTML code of the
918 page itself, but in separate HTML (sub)documents that are loaded into (i)frames
919 or (i)layers, and these external HTML documents are blocked. Being non-images
920 they get replaced by a substitute HTML page rather than a substitute image,
921 which wouldn't work out technically, since the browser expects and accepts
922 only HTML when it has requested an HTML document.
925 The substitute page adapts to the available space and shows itself as a
926 miniature two-liner if loaded into small frames, or full-blown with a
927 large red "BLOCKED" banner if space allows.
930 If you prefer the banners to be blocked by images, you must see to it that
931 the HTML documents in which they are embedded are not blocked. Clicking
932 the <quote>See why</quote> link offered in the substitute page will show
933 you which rule blocked the page. After changing the rule and un-blocking
934 the HTML documents, the browser will try to load the actual banner images
935 and the usual image blocking will (hopefully!) kick in.

1018 distinguish between web pages and HTML mail.
1019 <application>Privoxy</application> just blindly proxies all requests. In the

1033 <title>How can I allow permanent cookies for my trusted sites?</title>
1036 There are several actions that relate to cookies. The default behavior is to

1038 for the current browser session. This eliminates most kinds of abuse related
1039 to cookies. But there may be cases where we want cookies to last.

1099 action, the entire document must be loaded into memory in order for the filtering
1100 mechanism to work, and nothing is sent to the browser during this time.
1103 The loading time does not really change in real numbers, but the feeling is
1104 different, because most browsers are able to start rendering incomplete
1105 content, giving the user a feeling of "it works". This effect is especially
1106 noticeable on slow dialup connections.
1109 Filtering is automatically disabled for inappropriate MIME types. But note
1110 that if the web server mis-reports the MIME type, then content that should
1111 not be filtered, could be. <application>Privoxy</application> only knows how
1112 to differentiate filterable content because of the MIME type as reported by
1113 the server, or because of some configuration setting that enables/disables

1124 address of <application>Privoxy</application>'s built-in user interface, and
1125 <ulink url="http://p.p/">http://p.p/</ulink> is a shortcut for it.
1128 Since <application>Privoxy</application> sits between your web browser and the Internet,
1129 it can simply intercept requests for these addresses and answer them with its built-in
1130 <quote>web server</quote>.
1133 This also makes for a good test for your browser configuration: If entering the
1134 URL <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>
1135 takes you to a page saying <quote>This is Privoxy ...</quote>, everything is OK.
1136 If you get a page saying <quote>Privoxy is not working</quote> instead, then
1137 your browser didn't use <application>Privoxy</application> for the request,
1138 hence it could not be intercepted, and you have accessed the <emphasis>real</emphasis>
1139 web site at config.privoxy.org.
1142 With recent versions of <application>Privoxy</application> (version 2.9.x and

1184 <sect2 renderas="sect3" id="ip"><title>How can I hide my IP address?</title>
1186 If you run both the browser and the proxy locally, you cannot hide your IP
1187 address with <application>Privoxy</application> or any other software. The
1188 server needs to know your IP address to send the answers back to you.
1191 Fortunately there are many publicly usable anonymous proxies out there, which
1192 solve the problem by providing a further level of indirection between you and
1193 the web server, shared by many people, and thus letting your requests "drown"
1194 in white noise of unrelated requests as far as user tracking is concerned.
1197 Most of them will, however, log your IP address and make it available to the
1198 authorities in case you abuse that anonymity for criminal purposes. In fact
1199 you can't even rule out that some of them only exist to *collect* information
1200 on (those suspicious) people with a more than average preference for privacy.
1203 You can find a list of anonymous public proxies at <ulink
1204 url="http://www.multiproxy.org/anon_list.htm">multiproxy.org</ulink> and many
1205 more through Google. A particularly interesting project is the JAP service
1206 offered by the Technical University of Dresden (<ulink
1207 url="http://anon.inf.tu-dresden.de/index_en.html">http://anon.inf.tu-dresden.de/index_en.html</ulink>).
1210 There is, however, even in the single-machine case the possibility to make the
1211 server believe that your machine is in fact a shared proxy serving a whole big
1212 LAN, and we are looking into that.
1216 <sect2 renderas="sect3">
1217 <title id="anonforsure">Can <application>Privoxy</application> guarantee I am anonymous?</title>
1219 No. Your chances of remaining anonymous are greatly improved, but unless you
1220 are an expert on Internet security it would be safest to assume that
1221 everything you do on the Web can be traced back to you.
1224 <application>Privoxy</application> can remove various information about you,
1225 and allows <emphasis>you</emphasis> more freedom to decide which sites
1226 you can trust, and what details you want to reveal. But it's still possible
1227 that web sites can find out who you are. Here's one way this can happen.
1230 A few browsers disclose the user's email address in certain situations, such
1231 as when transferring a file by FTP. <application>Privoxy</application>
1232 does not filter FTP. If you need this feature, or are concerned about the
1233 mail handler of your browser disclosing your email address, you might
1234 consider products such as <application>NSClean</application>.
1237 Browsers available only as binaries could use non-standard headers to give
1238 out any information they can have access to: see the manufacturer's license
1239 agreement. It's impossible to anticipate and prevent every breach of privacy
1240 that might occur. The professionally paranoid prefer browsers available as
1241 source code, because anticipating their behavior is easier. Trust the source,
1247 <sect2 renderas="sect3">
1248 <title id="sitebreak">Might some things break because header information or
1249 content is being altered?</title>
1252 Definitely. More and more sites use HTTP header content to decide what to
1253 display and how to display it. There is many ways that this can be handled,
1254 so having hard and fast rules, is tricky.
1258 <quote>User-Agent</quote> in particular is often used in this way to identify
1259 the browser, and adjust content accordingly. Changing this now (at least not
1260 further than removing the OS information) is not recommended, since so many
1261 sites do look for it. You may get undesirable results by changing this.
1265 For instance, different browsers use different encodings of Russian and Czech
1266 characters, certain web servers convert pages on-the-fly according to the
1267 User Agent header. Giving a <quote>User Agent</quote> with the wrong
1268 operating system or browser manufacturer causes some sites in these languages
1269 to be garbled; Surfers to Eastern European sites should change it to
1270 something closer. And then some page access counters work by looking at the
1271 <quote>Referer</quote> header; they may fail or break if unavailable. The
1272 weather maps of Intellicast have been blocked by their server when no
1273 <quote>Referer</quote> or cookie is provided, is another example. (But you
1274 can forge both headers without giving information away). There are

1279 Similar thoughts apply to modifying JavaScript, and, to a lesser degree,
1284 If you have problems with a site, you will have to adjust your configuration
1285 accordingly. Cookies are probably the most likely adjustment that may
1286 be required, but by no means the only one.

1322 This is not a font problem. The logo is an image that is created by
1323 <application>Privoxy</application> on the fly. So as to not waste
1324 memory, the image is rather small. The blockiness comes when the
1325 image is scaled to fill a largish area. There is not much to be done
1326 about this, other than to use one of the other

1341 It would be technically possible eliminate the banners in a way that frees
1342 their screen estate in many cases, by doing all banner blocking with filters,
1343 i.e. eliminating the whole image references from the HTML pages instead
1344 of letting them stay in, and blocking the resulting requests for the
1348 But this would consume considerable CPU resources, would likely destroy
1349 the layout of many web pages which rely on the banners consuming a certain
1350 amount of screen space, and would fail in other cases, where the screen space
1351 is reserved e.g. by tables anyway. Also, making the banners disappear without
1352 a visual trace complicates troubleshooting.
1355 So we won't support this in the default configuration, but you can of course
1356 define appropriate filters yourself.

1361 <title id="ssl">How can <application>Privoxy</application> filter Secure (HTTPS) URLs?</title>
1363 Since secure HTTP connections are encrypted SSL sessions between your browser
1364 and the secure site, and are meant to be reliably <emphasis>secure</emphasis>,
1365 there is little that <application>Privoxy</application> can do but hand the raw
1366 gibberish data though from one end to the other unprocessed.
1369 The only exception to this is blocking by host patterns, as the client needs
1370 to tell <application>Privoxy</application> the name of the remote server,
1371 so that <application>Privoxy</application> can establish the connection.
1372 If that name matches a host-only pattern, the connection will be blocked.
1375 As far as ad blocking is concerned, this is less of a restriction than it may
1376 seem, since ad sources are often identifiable by the host name, and often
1377 the banners to be placed in an encrypted page come unencrypted nonetheless
1378 for efficiency reasons, which exposes them to the full power of

1385 in an SSL transaction will be impossible to block under these conditions.

1402 <application>Privoxy</application> is not itself directly exposed to the
1403 Internet in this configuration. If you want to have
1404 <application>Privoxy</application> serve as a LAN proxy, this will have to
1405 be opened up to allow for LAN requests. In this case, we'd recommend
1406 you specify only the LAN gateway address, e.g. 192.168.1.1, in the main

1447 banners, but <application>Privoxy</application> uses the same mechanism for

1451 intercepted (i.e. it does not go out to the 'net), and the familiar CGI

1458 <title>Can <application>Privoxy</application> effect files that I download
1459 from a webserver? FTP server?</title>
1461 From the webserver's perspective, there is no difference between
1462 viewing a document (i.e. a page), and downloading a file. The same is true of
1463 <application>Privoxy</application>. If there is a match for a <literal><ulink
1464 url="../user-manual/actions-file.html#BLOCK">block</ulink></literal> pattern,
1465 it will still be blocked, and of course this is obvious. Filtering is
1466 potentially more of a concern since the results are not always so obvious,
1467 and the effects of filtering are there whether the file is simply viewed, or
1471 <application>Privoxy</application> knows the differences in files according
1472 to the <quote>Document Type</quote> as reported by the webserver. If this is
1473 reported accurately (e.g. <quote>application/zip</quote> for a zip archive),
1474 then <application>Privoxy</application> knows to ignore these where
1475 appropriate. <application>Privoxy</application> filters html as well as plain
1476 text documents. Also, documents that are of an unknown type (generally
1477 assumed to be <quote>text/plain</quote>) will be filtered, as will those that
1478 might be incorrectly reported by the webserver. If such a file is a
1479 downloaded file that is intended to be saved to disk, then any content that
1480 might have been altered by filtering, will be saved too, for these (probably
1484 If you download text files, you probably do not want these to be filtered,

1596 and then shift-reloading the problem page (i.e. holding down the shift key

1602 If still a problem, go to <ulink
1603 url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>
1604 and paste the full URL of the page in question into the prompt. See which actions
1605 are being applied to the URL, and which matches in which actions files are
1606 responsible for that. Now, armed with this information, go to <ulink
1607 url="http://config.privoxy.org/show-status">http://config.privoxy.org/show-status</ulink>
1608 and select the appropriate actions files for editing.
1611 You can now either look for a section which disables the actions that
1612 you suspect to cause the problem and add a pattern for your site there,
1613 or make up a completely new section for your site. In any case, the recommended
1614 way is to disable only the prime suspect, reload the problem page, and only
1615 if the problem persists, disable more and more actions until you have
1616 identified the culprit. You may or may not want to turn the other actions
1617 on again. Remember to flush your browser's caches in between any such changes!
1620 Alternately, if you are comfortable with a text editor, you can accomplish
1621 the same thing by editing the appropriate actions file. Probably the easiest
1622 way to deal with such problems when editing by hand is to add your
1623 site to a <literal>{ fragile }</literal> section in <filename>user.action</filename>,
1624 which is an alias that turns off most <quote>dangerous</quote>

1640 <title>After installing <application>Privoxy</application>, I have to log in
1641 every time I start IE. What gives?</title>
1644 This is a quirk that effects the installation of
1645 <application>Privoxy</application>, in conjunction with Internet Explorer and
1646 Internet Connection Sharing on Windows 2000 and Windows XP. The symptoms may
1647 appear to be corrupted or invalid DUN settings, or passwords.
1651 When setting up an NT based Windows system with
1652 <application>Privoxy</application> you may find that things do not seem to be
1653 doing what you expect. When you set your system up you will probably have set
1654 up Internet Connection Sharing (ICS) with Dial up Networking (DUN) when
1655 logged in with administrator privileges. You will probably have made this DUN
1656 connection available to other accounts that you may have set-up on your
1657 system. E.g. Mum or Dad sets up the system and makes accounts suitably
1658 configured for the kids.
1662 When setting up <application>Privoxy</application> in this environment you
1663 will have to alter the proxy set-up of Internet Explorer (IE) for the
1664 specific DUN connection on which you wish to use
1665 <application>Privoxy</application>. When you do this the ICS DUN set-up
1666 becomes user specific. In this instance you will see no difference if you
1667 change the DUN connection under the account used to set-up the connection.
1668 However when you do this from another user you will notice that the DUN
1669 connection changes to make available to "Me only". You will also find that
1670 you have to store the password under each different user!
1674 The reason for this is that each user's set-up for IE is user specific. Each
1675 set-up DUN connection and each LAN connection in IE store the settings for
1676 each user individually. As such this enforces individual configurations
1677 rather than common ones. Hence the first time you use a DUN connection after
1678 re-booting your system it may not perform as you expect, and prompt you for
1679 the password. Just set and save the password again and all should be OK.
