30 Print version info and exit.
31 <DT><B>--no-daemon</B><DD>
32 Don't become a daemon, i.e. don't fork and become process group

35 On startup, write the process ID to <I>pidfile</I>.
36 Delete the <I>pidfile</I> on exit.
37 Failure to create or delete the <I>pidfile</I>
38 is non-fatal. If no <B>--pidfile</B> option is given, no PID file will be used.
39 <DT><B>--user </B><I>user[.group]</I><B></B><DD>
40 After (optionally) writing the PID file, assume the user ID of
41 <I>user</I> and the GID of
42 <I>group</I>, or, if the optional
43 <I>group</I> was not given, the default group of
44 <I>user</I>. Exit if the privileges are not
46 <DT><B>--chroot</B><DD>
47 Before changing to the user ID given in the --user option, chroot to
48 that user's home directory, i.e. make the kernel pretend to the
49 <B>Privoxy</B> process that the directory tree starts
50 there. If set up carefully, this can limit the impact of possible
51 vulnerabilities in <B>Privoxy</B> to the files contained in
53 <DT><B>--pre-chroot-nslookup </B><I>hostname</I><B></B><DD>
54 Initialize the resolver library using <I>hostname</I>
55 before chroot'ing. On some systems this reduces the number of files
56 that must be copied into the chroot tree.
60 If the <I>configfile</I> is not specified on the command line,
61 <B>Privoxy</B> will look for a file named
62 <I>config</I> in the current directory. If no

70 Privoxy is a non-caching web proxy with advanced filtering capabilities
71 for enhancing privacy, modifying web page data and HTTP headers, controlling
72 access, and removing ads and other obnoxious Internet junk. Privoxy has a
73 flexible configuration and can be customized to suit individual needs and tastes.
74 It has application for both stand-alone systems and multi-user networks.
77 Privoxy is Free Software and licensed under the GNU GPLv2.
80 Privoxy is an associated project of Software in the Public Interest (SPI).

91 <H2>INSTALLATION AND USAGE</H2>
95 Browsers can either be individually configured to use
96 <B>Privoxy</B> as a HTTP proxy (recommended),
97 or <B>Privoxy</B> can be combined with a packet
98 filter to build an intercepting proxy
99 (see <I>config</I>). The default setting is for
100 localhost, on port 8118 (configurable in the main config file). To set the
101 HTTP proxy in Firefox, go through: <B>Tools</B>;
102 <B>Options</B>; <B>General</B>;
103 <B>Connection Settings</B>;
104 <B>Manual Proxy Configuration</B>.
107 For Internet Explorer, go through: <B>Tools</B>;
108 <B>Internet Properties</B>; <B>Connections</B>;
112 The Secure (SSL) Proxy should also be set to the same values, otherwise
113 https: URLs will not be proxied. Note: <B>Privoxy</B> can only
114 proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols.
115 HTTPS presents some limitations, and not all features will work with HTTPS
119 For other browsers, check the documentation.
120 <A NAME="lbAG"> </A>
121 <H2>CONFIGURATION</H2>
125 <B>Privoxy</B> can be configured with the various configuration
126 files. The default configuration files are: <I>config</I>,
127 <I>default.filter</I>, <I>default.action</I> and
128 <I>default.action</I>. <I>user.action</I> should
129 be used for locally defined exceptions to the default rules in
130 <I>match-all.action</I> and <I>default.action</I>,
131 and <I>user.filter</I> for locally defined filters. These are
132 well commented. On Unix and Unix-like systems, these are located in
133 <I>/etc/privoxy/</I> by default.
136 <B>Privoxy</B> uses the concept of <B>actions</B>
137 in order to manipulate the data stream between the browser and remote sites.
138 There are various actions available with specific functions for such things
139 as blocking web sites, managing cookies, etc. These actions can be invoked
140 individually or combined, and used against individual URLs, or groups of URLs
141 that can be defined using wildcards and regular expressions. The result is
142 that the user has greatly enhanced control and freedom.
145 The actions list (ad blocks, etc) can also be configured with your
146 web browser at <A HREF="http://config.privoxy.org/">http://config.privoxy.org/</A>
147 (assuming the configuration allows it).
148 <B>Privoxy's</B> configuration parameters can also be viewed at
149 the same page. In addition, <B>Privoxy</B> can be toggled on/off.
150 This is an internal page, and does not require Internet access.
153 See the <I>User Manual</I> for a detailed
154 explanation of installation, general usage, all configuration options, new
155 features and notes on upgrading.

184 <B>Privoxy</B> terminates on the <B>SIGINT</B>,
185 <B>SIGTERM</B> and <B>SIGABRT</B> signals. Log
186 rotation scripts may cause a re-opening of the logfile by sending a
187 <B>SIGHUP</B> to <B>Privoxy</B>. Note that unlike
188 other daemons, <B>Privoxy</B> does not need to be made aware of
189 config file changes by <B>SIGHUP</B> -- it will detect them
