- </p>
- <p>
- One of <span class="APPLICATION">Privoxy's</span> strengths is that
- it is highly configurable giving you the ability to completely

- having an interest in learning about <a href=

- very basic configuration. The user should take this as a starting
- point only, and enhance it as he or she sees fit. In fact, the user
- is encouraged, and expected to, fine-tune the configuration.
- </p>
- <p>
- Much of <span class="APPLICATION">Privoxy's</span> configuration
- can be done with a <a href=

- the web-based action editor doesn't use authentication and should
- only be enabled in environments where all clients with access to

- <a name="PROXYMORON">1.3. What is a <span class=

- </h3>
- <p>
- A <a href="http://en.wikipedia.org/wiki/Proxy_server" target=
- "_top">web proxy</a> is a service, based on a software such as
- <span class="APPLICATION">Privoxy</span>, that clients (i.e.
- browsers) can use instead of connecting to web servers directly.
- The clients then ask the proxy to request objects (web pages,
- images, movies etc) on their behalf and to forward the data to the
- clients. It is a <span class="QUOTE">"go-between"</span>. For
- details, see <a href="http://en.wikipedia.org/wiki/Proxy_server"
- target="_top">Wikipedia's proxy definition</a>.
- </p>
- <p>
- There are many reasons to use web proxies, such as security
- (firewalling), efficiency (caching) and others, and there are any
- number of proxies to accommodate those needs.
- </p>
- <p>
- <span class="APPLICATION">Privoxy</span> is a proxy that is
- primarily focused on privacy enhancement, ad and junk elimination
- and freeing the user from restrictions placed on his activities.
- Sitting between your browser(s) and the Internet, it is in a
- perfect position to filter outbound personal information that your
- browser is leaking, as well as inbound junk. It uses a variety of
- techniques to do this, all of which are under your complete control
- via the various configuration files and options. Being a proxy also
- makes it easier to share configurations among multiple browsers
- and/or users.

- <a name="OTHERSTUFF">1.4. Does Privoxy do anything more than ad

- <a name="NEWJB">1.5. What is this new version of <span class=
- "QUOTE">"Junkbuster"</span>?</a>
- </h3>
- <p>
- A long time ago, there was the <span class="APPLICATION">Internet
- Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
- This saved many users a lot of pain in the early days of web
- advertising and user tracking.
- </p>
- <p>
- But the web, its protocols and standards, and with it, the
- techniques for forcing ads on users, give up autonomy over their
- browsing, and for tracking them, keeps evolving. Unfortunately, the
- <span class="APPLICATION">Internet Junkbuster</span> did not.
- Version 2.0.2, published in 1998, was the last official release,
- available from Junkbusters Corporation. Fortunately, it had been
- released under the GNU <a href=
- "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
- "_top">GPL</a>, which allowed further development by others.
- </p>
- <p>
- So Stefan Waldherr started maintaining an improved version of the
- software, to which eventually a number of people contributed
- patches. It could already replace banners with a transparent image,
- and had a first version of pop-up killing, but it was still very
- closely based on the original, with all its limitations, such as
- the lack of HTTP/1.1 support, flexible per-site configuration, or
- content modification. The last release from this effort was version
- 2.0.2-10, published in 2000.
- </p>
- <p>
- Then, some <a href=
- "https://www.privoxy.org/user-manual/copyright.html#AUTHORS"
- target="_top">developers</a> picked up the thread, and started
- turning the software inside out, upside down, and then reassembled
- it, adding many <a href=
- "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
- target="_top">new features</a> along the way.
- </p>
- <p>
- The result of this is <span class="APPLICATION">Privoxy</span>,
- whose first stable version, 3.0, was released August, 2002.
- </p>
- <p>
- As of 2012 the Junkbusters Corporation's website
- (http://www.junkbusters.com/) has been shut down, but Privoxy is
- still actively maintained.

- <p>
- Though outdated, Junkbusters Corporation continued to offer their
- original version of the <span class="APPLICATION">Internet
- Junkbuster</span> for a while, so publishing our <span class=
- "APPLICATION">Junkbuster</span>-derived software under the same
- name would have led to confusion.
- </p>
- <p>
- There were also potential legal reasons not to use the <span class=
- "APPLICATION">Junkbuster</span> name, as it was (and maybe still
- is) a registered trademark of Junkbusters Corporation. There were,
- however, no objections from Junkbusters Corporation to the <span
- class="APPLICATION">Privoxy</span> project itself, and they, in
- fact, shared our ideals and goals.
- </p>
- <p>
- The Privoxy developers also believed that there were so many
- improvements over the original code, that it was time to make a
- clean break from the past and make a name in their own right.

- <span class="APPLICATION">Privoxy</span> is the <span class=

- <p>
- <span class="APPLICATION">Privoxy</span> picks up where <span

- "APPLICATION">Privoxy</span> still blocks ads and banners, still
- manages <a href="http://en.wikipedia.org/wiki/Browser_cookie"

- But, most of these features have been enhanced, and many new ones
- have been added, all in the same vein.
- </p>
- <p>
- <span class="APPLICATION">Privoxy</span>'s new features include:
- </p>
- <p>
- </p>
- <ul>
- <li>
- <p>
- Supports "Connection: keep-alive". Outgoing connections can be
- kept alive independently from the client.
- </p>
- </li>
- <li>
- <p>
- Supports IPv6, provided the operating system does so too, and
- the configure script detects it.
- </p>
- </li>
- <li>
- <p>
- Supports tagging which allows to change the behaviour based on
- client and server headers.
- </p>
- </li>
- <li>
- <p>
- Can be run as an "intercepting" proxy, which obviates the need
- to configure browsers individually.
- </p>
- </li>
- <li>
- <p>
- Sophisticated actions and filters for manipulating both server
- and client headers.
- </p>
- </li>
- <li>
- <p>
- Can be chained with other proxies.
- </p>
- </li>
- <li>
- <p>
- Integrated browser-based configuration and control utility at
- <a href="http://config.privoxy.org/" target=
- "_top">http://config.privoxy.org/</a> (shortcut: <a href=
- "http://p.p/" target="_top">http://p.p/</a>). Browser-based
- tracing of rule and filter effects. Remote toggling.
- </p>
- </li>
- <li>
- <p>
- Web page filtering (text replacements, removes banners based on
- size, invisible <span class="QUOTE">"web-bugs"</span> and HTML
- annoyances, etc.)
- </p>
- </li>
- <li>
- <p>
- Modularized configuration that allows for standard settings and
- user settings to reside in separate files, so that installing
- updated actions files won't overwrite individual user settings.
- </p>
- </li>
- <li>
- <p>
- Support for Perl Compatible Regular Expressions in the
- configuration files, and a more sophisticated and flexible
- configuration syntax.
- </p>
- </li>
- <li>
- <p>
- GIF de-animation.
- </p>
- </li>
- <li>
- <p>
- Bypass many click-tracking scripts (avoids script redirection).
- </p>
- </li>
- <li>
- <p>
- User-customizable HTML templates for most proxy-generated pages
- (e.g. "blocked" page).
- </p>
- </li>
- <li>
- <p>
- Auto-detection and re-reading of config file changes.
- </p>
- </li>
- <li>
- <p>
- Most features are controllable on a per-site or per-location

- <a name="WHATSANAD">1.8. How does Privoxy know what is an ad, and
- what is not?</a>
- </h3>
- <p>
- <span class="APPLICATION">Privoxy</span>'s approach to blocking ads
- is twofold:
- </p>
- <p>
- First, there are certain patterns in the <span class="emphasis"><i
- class="EMPHASIS">locations</i></span> (URLs) of banner images. This
- applies to both the path (you wouldn't guess how many web sites
- serve their banners from a directory called <span class=
- "QUOTE">"banners"</span>!) and the host (blocking the big banner
- hosting services like doublecklick.net already helps a lot). <span
- class="APPLICATION">Privoxy</span> takes advantage of this fact by
- using <a href="../user-manual/actions-file.html#AF-PATTERNS"
- target="_top">URL patterns</a> to sort out and block the requests
- for things that sound like they would be ads or banners.
- </p>
- <p>
- Second, banners tend to come in certain <span class="emphasis"><i
- class="EMPHASIS">sizes</i></span>. But you can't tell the size of
- an image by its URL without downloading it, and if you do, it's too
- late to save bandwidth. Therefore, <span class=
- "APPLICATION">Privoxy</span> also inspects the HTML sources of web
- pages while they are loaded, and replaces references to images with
- standard banner sizes by dummy references, so that your browser
- doesn't request them anymore in the first place.
- </p>
- <p>
- Both of this involves a certain amount of guesswork and is, of
- course, freely and readily configurable.
- </p>
- </div>
- <div class="SECT2">
- <h3 class="SECT2">
- <a name="MISTAKES">1.9. Can Privoxy make mistakes? This does not
- sound very scientific.</a>
- </h3>
- <p>
- Actually, it's a black art ;-) And yes, it is always possible to
- have a broad rule accidentally block or change something by
- mistake. You will almost surely run into such situations at some
- point. It is tricky writing rules to cover every conceivable
- possibility, and not occasionally get false positives.
- </p>
- <p>
- But this should not be a big concern since the <span class=
- "APPLICATION">Privoxy</span> configuration is very flexible, and
- includes tools to help identify these types of situations so they
- can be addressed as needed, allowing you to customize your
- installation. (<a href="trouble.html#BADSITE">See the
- Troubleshooting section below</a>.)
- </p>
- </div>
- <div class="SECT2">
- <h3 class="SECT2">
- <a name="CONFIGORNOT">1.10. Will I have to configure Privoxy before
- I can use it?</a>
- </h3>
- <p>
- That depends on your expectations. The default installation should
- give you a good starting point, and block <span class="emphasis"><i
- class="EMPHASIS">most</i></span> ads and unwanted content, but many
- of the more advanced features are off by default, and require you
- to activate them.
- </p>
- <p>
- You do have to set up your browser to use <span class=
- "APPLICATION">Privoxy</span> (see the <a href=
- "installation.html#FIRSTSTEP">Installation section below</a>).
- </p>
- <p>
- And you will certainly run into situations where there are false
- positives, or ads not being blocked that you may not want to see.
- In these cases, you would certainly benefit by customizing <span
- class="APPLICATION">Privoxy's</span> configuration to more closely
- match your individual situation. And we encourage you to do this.
- This is where the real power of <span class=

- <div class="SECT2">
- <h3 class="SECT2">
- <a name="LAN">1.11. Can Privoxy run as a server on a network?</a>

- <p>
- Yes, <span class="APPLICATION">Privoxy</span> runs as a server
- already, and can easily be configured to <span class=
- "QUOTE">"serve"</span> more than one client. See <a href=
- "configuration.html#LANCONFIG">How can I set up Privoxy to act as a

- <a name="BROWSERS2">1.12. My browser does the same things as

- <p>
- Modern browsers do indeed have <span class="emphasis"><i class=
- "EMPHASIS">some</i></span> of the same functionality as <span
- class="APPLICATION">Privoxy</span>. Maybe this is adequate for you.
- But <span class="APPLICATION">Privoxy</span> is very versatile and
- powerful, and can probably do a number of things your browser just
- can't.
- </p>
- <p>
- In addition, a proxy is good choice if you use multiple browsers,
- or have a LAN with multiple computers since <span class=
- "APPLICATION">Privoxy</span> can run as a server application. This
- way all the configuration is in one place, and you don't have to
- maintain a similar configuration for possibly many browsers or
- users.
- </p>
- <p>
- Note, however, that it's recommended to leverage both your
- browser's and <span class="APPLICATION">Privoxy's</span> privacy
- enhancing features at the same time. While your browser probably
- lacks some features <span class="APPLICATION">Privoxy</span>
- offers, it should also be able to do some things more reliably, for
- example restricting and suppressing JavaScript.

- <div class="SECT2">
- <h3 class="SECT2">
- <a name="WHYTRUST">1.13. Why should I trust Privoxy?</a>
- </h3>
- <p>
- The most important reason is because you have access to <span
- class="emphasis"><i class="EMPHASIS">everything</i></span>, and you
- can control everything. You can check every line of every
- configuration file yourself. You can check every last bit of source
- code should you desire. And even if you can't read code, there
- should be some comfort in knowing that other people can, and do
- read it. You can build the software from scratch, if you want, so
- that you know the executable is clean, and that it is <span class=
- "emphasis"><i class="EMPHASIS">yours</i></span>. In fact, we

+ <p>A <a href="http://en.wikipedia.org/wiki/Proxy_server" target=

+ <span class="APPLICATION">Privoxy</span>, that clients (i.e. browsers)

+ ask the proxy to request objects (web pages, images, movies etc) on

+ <span class="QUOTE">"go-between"</span>. For details, see <a href=
+ "http://en.wikipedia.org/wiki/Proxy_server" target="_top">Wikipedia's
+ proxy definition</a>.</p>
+ <p>There are many reasons to use web proxies, such as security
+ (firewalling), efficiency (caching) and others, and there are any
+ number of proxies to accommodate those needs.</p>
+ <p><span class="APPLICATION">Privoxy</span> is a proxy that is
+ primarily focused on privacy enhancement, ad and junk elimination and
+ freeing the user from restrictions placed on his activities. Sitting
+ between your browser(s) and the Internet, it is in a perfect position
+ to filter outbound personal information that your browser is leaking,
+ as well as inbound junk. It uses a variety of techniques to do this,
+ all of which are under your complete control via the various
+ configuration files and options. Being a proxy also makes it easier to
+ share configurations among multiple browsers and/or users.</p>

+ <p>A long time ago, there was the <span class="APPLICATION">Internet
+ Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
+ This saved many users a lot of pain in the early days of web
+ advertising and user tracking.</p>
+ <p>But the web, its protocols and standards, and with it, the
+ techniques for forcing ads on users, give up autonomy over their
+ browsing, and for tracking them, keeps evolving. Unfortunately, the
+ <span class="APPLICATION">Internet Junkbuster</span> did not. Version
+ 2.0.2, published in 1998, was the last official release, available from
+ Junkbusters Corporation. Fortunately, it had been released under the
+ GNU <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
+ target="_top">GPL</a>, which allowed further development by others.</p>
+ <p>So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches.
+ It could already replace banners with a transparent image, and had a
+ first version of pop-up killing, but it was still very closely based on
+ the original, with all its limitations, such as the lack of HTTP/1.1
+ support, flexible per-site configuration, or content modification. The
+ last release from this effort was version 2.0.2-10, published in
+ 2000.</p>
+ <p>Then, some <a href=
+ "https://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
+ "_top">developers</a> picked up the thread, and started turning the
+ software inside out, upside down, and then reassembled it, adding many
+ <a href=
+ "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
+ target="_top">new features</a> along the way.</p>
+ <p>The result of this is <span class="APPLICATION">Privoxy</span>,
+ whose first stable version, 3.0, was released August, 2002.</p>
+ <p>As of 2012 the Junkbusters Corporation's website

+ <li>
+ <p>Web page filtering (text replacements, removes banners based on
+ size, invisible <span class="QUOTE">"web-bugs"</span> and HTML
+ annoyances, etc.)</p>
+ </li>
+ <li>
+ <p>Modularized configuration that allows for standard settings and
+ user settings to reside in separate files, so that installing
+ updated actions files won't overwrite individual user settings.</p>
+ </li>
+ <li>
+ <p>Support for Perl Compatible Regular Expressions in the
+ configuration files, and a more sophisticated and flexible
+ configuration syntax.</p>
+ </li>
+ <li>
+ <p>GIF de-animation.</p>
+ </li>
+ <li>
+ <p>Bypass many click-tracking scripts (avoids script

+ Privoxy know what is an ad, and what is not?</a></h3>
+ <p><span class="APPLICATION">Privoxy</span>'s approach to blocking ads
+ is twofold:</p>
+ <p>First, there are certain patterns in the <span class=
+ "emphasis"><i class="EMPHASIS">locations</i></span> (URLs) of banner
+ images. This applies to both the path (you wouldn't guess how many web
+ sites serve their banners from a directory called <span class=
+ "QUOTE">"banners"</span>!) and the host (blocking the big banner
+ hosting services like doublecklick.net already helps a lot).
+ <span class="APPLICATION">Privoxy</span> takes advantage of this fact
+ by using <a href="../user-manual/actions-file.html#AF-PATTERNS" target=
+ "_top">URL patterns</a> to sort out and block the requests for things
+ that sound like they would be ads or banners.</p>
+ <p>Second, banners tend to come in certain <span class=
+ "emphasis"><i class="EMPHASIS">sizes</i></span>. But you can't tell the
+ size of an image by its URL without downloading it, and if you do, it's
+ too late to save bandwidth. Therefore, <span class=
+ "APPLICATION">Privoxy</span> also inspects the HTML sources of web
+ pages while they are loaded, and replaces references to images with
+ standard banner sizes by dummy references, so that your browser doesn't
+ request them anymore in the first place.</p>
+ <p>Both of this involves a certain amount of guesswork and is, of
+ course, freely and readily configurable.</p>
+ </div>
+ <div class="SECT2">
+ <h3 class="SECT2"><a name="MISTAKES" id="MISTAKES">1.9. Can Privoxy
+ make mistakes? This does not sound very scientific.</a></h3>
+ <p>Actually, it's a black art ;-) And yes, it is always possible to
+ have a broad rule accidentally block or change something by mistake.
+ You will almost surely run into such situations at some point. It is
+ tricky writing rules to cover every conceivable possibility, and not
+ occasionally get false positives.</p>
+ <p>But this should not be a big concern since the <span class=
+ "APPLICATION">Privoxy</span> configuration is very flexible, and
+ includes tools to help identify these types of situations so they can
+ be addressed as needed, allowing you to customize your installation.
+ (<a href="trouble.html#BADSITE">See the Troubleshooting section

+ </div>
+ <div class="SECT2">
+ <h3 class="SECT2"><a name="CONFIGORNOT" id="CONFIGORNOT">1.10. Will I
+ have to configure Privoxy before I can use it?</a></h3>
+ <p>That depends on your expectations. The default installation should
+ give you a good starting point, and block <span class=
+ "emphasis"><i class="EMPHASIS">most</i></span> ads and unwanted
+ content, but many of the more advanced features are off by default, and
+ require you to activate them.</p>
+ <p>You do have to set up your browser to use <span class=

+ <p>And you will certainly run into situations where there are false

+ <h3 class="SECT2"><a name="LAN" id="LAN">1.11. Can Privoxy run as a

+ <p>Modern browsers do indeed have <span class="emphasis"><i class=
+ "EMPHASIS">some</i></span> of the same functionality as <span class=
+ "APPLICATION">Privoxy</span>. Maybe this is adequate for you. But
+ <span class="APPLICATION">Privoxy</span> is very versatile and
+ powerful, and can probably do a number of things your browser just
+ can't.</p>
+ <p>In addition, a proxy is good choice if you use multiple browsers, or
+ have a LAN with multiple computers since <span class=
+ "APPLICATION">Privoxy</span> can run as a server application. This way
+ all the configuration is in one place, and you don't have to maintain a
+ similar configuration for possibly many browsers or users.</p>
+ <p>Note, however, that it's recommended to leverage both your browser's
+ and <span class="APPLICATION">Privoxy's</span> privacy enhancing
+ features at the same time. While your browser probably lacks some
+ features <span class="APPLICATION">Privoxy</span> offers, it should
+ also be able to do some things more reliably, for example restricting

+ <div class="SECT2">
+ <h3 class="SECT2"><a name="WHYTRUST" id="WHYTRUST">1.13. Why should I

+ control everything. You can check every line of every configuration
+ file yourself. You can check every last bit of source code should you
+ desire. And even if you can't read code, there should be some comfort
+ in knowing that other people can, and do read it. You can build the
+ software from scratch, if you want, so that you know the executable is
+ clean, and that it is <span class="emphasis"><i class=
