55 <p>This documentation is included with the current stable version of
56 <span class="APPLICATION">Privoxy</span>, v.3.0.18.</p>
59 <h2 class="SECT2"><a name="FEATURES" id="FEATURES">1.1.
62 <p>In addition to the core features of ad blocking and <a href=
63 "http://en.wikipedia.org/wiki/Browser_cookie" target="_top">cookie</a>
64 management, <span class="APPLICATION">Privoxy</span> provides many
65 supplemental features, that give the end-user more control, more
66 privacy and more freedom:</p>
70 <p>Supports "Connection: keep-alive". Outgoing connections can be
71 kept alive independently from the client.</p>
75 <p>Supports IPv6, provided the operating system does so too, and
76 the configure script detects it.</p>
80 <p>Supports tagging which allows to change the behaviour based on
81 client and server headers.</p>
85 <p>Can be run as an "intercepting" proxy, which obviates the need
86 to configure browsers individually.</p>
90 <p>Sophisticated actions and filters for manipulating both server
91 and client headers.</p>
95 <p>Can be chained with other proxies.</p>
99 <p>Integrated browser-based configuration and control utility at
100 <a href="http://config.privoxy.org/" target=
101 "_top">http://config.privoxy.org/</a> (shortcut: <a href=
102 "http://p.p/" target="_top">http://p.p/</a>). Browser-based tracing
103 of rule and filter effects. Remote toggling.</p>
107 <p>Web page filtering (text replacements, removes banners based on
108 size, invisible <span class="QUOTE">"web-bugs"</span> and HTML
109 annoyances, etc.)</p>
113 <p>Modularized configuration that allows for standard settings and
114 user settings to reside in separate files, so that installing
115 updated actions files won't overwrite individual user settings.</p>
119 <p>Support for Perl Compatible Regular Expressions in the
120 configuration files, and a more sophisticated and flexible
121 configuration syntax.</p>
125 <p>GIF de-animation.</p>
129 <p>Bypass many click-tracking scripts (avoids script
134 <p>User-customizable HTML templates for most proxy-generated pages
135 (e.g. "blocked" page).</p>
139 <p>Auto-detection and re-reading of config file changes.</p>
143 <p>Most features are controllable on a per-site or per-location
148 <p>Many smaller new features added, limitations and bugs
