45 <p style="margin-left:22%;">Before changing to the user ID given in the −−user option, chroot to that
46 user’s home directory, i.e. make the kernel pretend to the <b>Privoxy</b> process that the directory tree
47 starts there. If set up carefully, this can limit the impact of possible vulnerabilities in <b>Privoxy</b> to the
48 files contained in that hierarchy.</p>

51 code signals whether or not the configuration files have been successfully loaded.</p>
52 <p style="margin-left:22%; margin-top: 1em">If the exit code is 1, at least one of the configuration files is
53 invalid, if it is 0, all the configuration files have been successfully loaded (but may still contain errors that can
54 currently only be detected at run time).</p>
55 <p style="margin-left:22%; margin-top: 1em">This option doesn’t affect the log setting, combination with
56 "--no-daemon" is recommended if a configured log file shouldn’t be used.</p>

90 <p style="margin-left:11%; margin-top: 1em">Privoxy is a non-caching web proxy with advanced filtering capabilities
91 for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other
92 obnoxious Internet junk. Privoxy has a flexible configuration and can be customized to suit individual needs and
93 tastes. It has application for both stand-alone systems and multi-user networks.</p>
94 <p style="margin-left:11%; margin-top: 1em">Privoxy is Free Software and licensed under the GNU GPLv2 or later.</p>
95 <p style="margin-left:11%; margin-top: 1em">Privoxy is an associated project of Software in the Public Interest

121 </table><a name="INSTALLATION AND USAGE"></a>
122 <h2>INSTALLATION AND USAGE</h2>
123 <p style="margin-left:11%; margin-top: 1em">Browsers can either be individually configured to use <b>Privoxy</b> as a
124 HTTP proxy (recommended), or <b>Privoxy</b> can be combined with a packet filter to build an intercepting proxy (see
125 <i>config</i>). The default setting is for localhost, on port 8118 (configurable in the main config file). To set the
126 HTTP proxy in Firefox, go through: <b>Tools</b>; <b>Options</b>; <b>General</b>; <b>Connection Settings</b>;
127 <b>Manual Proxy Configuration</b>.</p>
128 <p style="margin-left:11%; margin-top: 1em">For Internet Explorer, go through: <b>Tools</b>; <b>Internet
129 Properties</b>; <b>Connections</b>; <b>LAN Settings</b>.</p>
130 <p style="margin-left:11%; margin-top: 1em">The Secure (SSL) Proxy should also be set to the same values, otherwise
131 https: URLs will not be proxied. Note: <b>Privoxy</b> can only proxy HTTP and HTTPS traffic. Do not try it with FTP
132 or other protocols. HTTPS presents some limitations, and not all features will work with HTTPS connections.</p>
133 <p style="margin-left:11%; margin-top: 1em">For other browsers, check the documentation.</p><a name=
135 <h2>CONFIGURATION</h2>
136 <p style="margin-left:11%; margin-top: 1em"><b>Privoxy</b> can be configured with the various configuration files.
137 The default configuration files are: <i>config</i>, <i>default.filter</i>, <i>default.action</i> and
138 <i>default.action</i>. <i>user.action</i> should be used for locally defined exceptions to the default rules in
139 <i>match-all.action</i> and <i>default.action</i>, and <i>user.filter</i> for locally defined filters. These are well
140 commented. On Unix and Unix-like systems, these are located in <i>/etc/privoxy/</i> by default.</p>
141 <p style="margin-left:11%; margin-top: 1em"><b>Privoxy</b> uses the concept of <b>actions</b> in order to manipulate
142 the data stream between the browser and remote sites. There are various actions available with specific functions for
143 such things as blocking web sites, managing cookies, etc. These actions can be invoked individually or combined, and
144 used against individual URLs, or groups of URLs that can be defined using wildcards and regular expressions. The
145 result is that the user has greatly enhanced control and freedom.</p>
146 <p style="margin-left:11%; margin-top: 1em">The actions list (ad blocks, etc) can also be configured with your web
147 browser at http://config.privoxy.org/ (assuming the configuration allows it). <b>Privoxy’s</b> configuration
148 parameters can also be viewed at the same page. In addition, <b>Privoxy</b> can be toggled on/off. This is an
149 internal page, and does not require Internet access.</p>
150 <p style="margin-left:11%; margin-top: 1em">See the <i>User Manual</i> for a detailed explanation of installation,
151 general usage, all configuration options, new features and notes on upgrading.</p><a name="FILES"></a>

167 <p style="margin-left:11%; margin-top: 1em"><b>Privoxy</b> terminates on the <b>SIGINT</b> and <b>SIGTERM</b>
168 signals. Log rotation scripts may cause a re-opening of the logfile by sending a <b>SIGHUP</b> to <b>Privoxy</b>.
169 Note that unlike other daemons, <b>Privoxy</b> does not need to be made aware of config file changes by <b>SIGHUP</b>
170 -- it will detect them automatically. Signals other than the ones listed above aren’t explicitly handled and
171 result in the default action defined by the operating system.</p><a name="NOTES"></a>
