22 (DTD, etc) cannot be sourced as a secondary file. config.sgml is basically
23 a wrapper for this file.
27 OPTIONS: The actual options are included in this file and prefixed with
28 '@@', and processed by the Makefile to strip the '@@'. Default options
29 that should appear commented out should be listed as: '@@#OPTION'.
30 Otherwise, as '@@OPTION'. Example:

126 <literallayout>I. INTRODUCTION
127 =============== <!-- fuck this madness --></literallayout>
130 This file holds Privoxy's main configuration. Privoxy detects
131 configuration changes automatically, so you don't have to restart it
132 unless you want to load a different configuration file.
135 The configuration will be reloaded with the first request after the
136 change was done, this request itself will still use the old configuration,
137 though. In other words: it takes two requests before you see the result of
138 your changes. Requests that are dropped due to ACL don't trigger reloads.
141 When starting Privoxy on Unix systems, give the location of this
142 file as last argument. On Windows systems, Privoxy will look for
143 this file with the name 'config.txt' in the current working directory
144 of the Privoxy process.

150 II. FORMAT OF THE CONFIGURATION FILE
151 ====================================</literallayout>
154 Configuration lines consist of an initial keyword followed by a list
155 of values, all separated by whitespace (any number of spaces or
159 actionsfile default.action
162 Indicates that the actionsfile is named 'default.action'.
165 The '#' indicates a comment. Any part of a line following a '#' is
166 ignored, except if the '#' is preceded by a '\'.
169 Thus, by placing a # at the start of an existing configuration line,
170 you can make it a comment and it will be treated as if it weren't there.
171 This is called "commenting out" an option and can be useful. Removing
172 the # again is called "uncommenting".
175 Note that commenting out an option and leaving it at its default
176 are two completely different things! Most options behave very
177 differently when unset. See the "Effect if unset" explanation
178 in each option's description for details.

240 The User Manual URI is the single best source of information on
241 <application>Privoxy</application>, and is used for help links from some
242 of the internal CGI pages. The manual itself is normally packaged with the
243 binary distributions, so you probably want to set this to a locally
251 Unix, in local filesystem (may not work with all browsers):
254 <screen> user-manual file:///usr/share/doc/privoxy-&p-version;/user-manual/</screen>
257 Windows, in local filesystem, <emphasis>must</emphasis> use forward slash notation:
260 <screen> user-manual file:/c:/some-dir/privoxy-&p-version;/user-manual/</screen>
263 Windows, UNC notation (with forward slashes):
266 <screen> user-manual file://///some-server/some-path/privoxy-&p-version;/user-manual/</screen>
270 The best all purpose solution is simply to put the full local
271 <literal>PATH</literal> to where the <citetitle>User Manual</citetitle> is
275 <screen> user-manual /usr/share/doc/privoxy/user-manual</screen>
278 The User Manual is then available to anyone with access to
279 <application>Privoxy</application>, by following the built-in URL:
280 <literal>http://config.privoxy.org/user-manual/</literal>
281 (or the shortcut: <literal>http://p.p/user-manual/</literal>).
284 If the documentation is not on the local system, it can be accessed
285 from a remote server, as:

912 If you specify a trust file, <application>Privoxy</application> will only allow
913 access to sites that are specified in the trustfile. Sites can be listed
917 Prepending a <literal>~</literal> character limits access to this site

919 <literal>~www.example.com</literal> allows access to

923 Or, you can designate sites as <emphasis>trusted referrers</emphasis>, by
924 prepending the name with a <literal>+</literal> character. The effect is that
925 access to untrusted sites will be granted -- but only if a link from this
926 trusted referrer was used to get there. The link target will then be added
927 to the <quote>trustfile</quote> so that future, direct accesses will be
928 granted. Sites added via this mechanism do not become trusted referrers
929 themselves (i.e. they are added with a <literal>~</literal> designation).
930 There is a limit of 512 such entries, after which new entries will not be

1221 recommended for home users who run <application>Privoxy</application> on
1222 the same machine as their browser.
1230 You will need to configure your browser(s) to this proxy address and port.
1233 If you already have another service running on port 8118, or if you want to
1234 serve requests from other machines (e.g. on your local network) as well, you
1235 will need to override the default.
1238 You can use this statement multiple times to make
1239 <application>Privoxy</application> listen on more ports or more
1240 <abbrev>IP</abbrev> addresses. Suitable if your operating system does not
1241 support sharing <abbrev>IPv6</abbrev> and <abbrev>IPv4</abbrev> protocols
1245 If a hostname is used instead of an IP address, <application>Privoxy</application>
1246 will try to resolve it to an IP address and if there are multiple, use the first
1250 If the address for the hostname isn't already known on the system
1251 (for example because it's in /etc/hostname), this may result in DNS
1255 If the specified address isn't available on the system, or if the
1256 hostname can't be resolved, <application>Privoxy</application>
1260 IPv6 addresses containing colons have to be quoted by brackets.
1261 They can only be used if <application>Privoxy</application> has
1262 been compiled with IPv6 support. If you aren't sure if your version
1263 supports it, have a look at
1264 <literal>http://config.privoxy.org/show-status</literal>.
1267 Some operating systems will prefer IPv6 to IPv4 addresses even if the
1268 system has no IPv6 connectivity which is usually not expected by the user.
1269 Some even rely on DNS to resolve localhost which mean the "localhost" address
1270 used may not actually be local.
1273 It is therefore recommended to explicitly configure the intended IP address
1274 instead of relying on the operating system, unless there's a strong reason not to.
1277 If you leave out the address, <application>Privoxy</application> will bind to all
1278 IPv4 interfaces (addresses) on your machine and may become reachable from the
1279 Internet and/or the local network. Be aware that some GNU/Linux distributions
1280 modify that behaviour without updating the documentation. Check for non-standard
1281 patches if your <application>Privoxy</application> version behaves differently.
1284 If you configure <application>Privoxy</application> to be reachable from the
1285 network, consider using <link linkend="acls">access control lists</link>
1286 (ACL's, see below), and/or a firewall.

1607 <application>Privoxy</application> is mainly used to block and filter

1735 for a particular destination URL, the <replaceable class="parameter">dst_addr</replaceable>
1736 that is examined is the address of the forwarder and <emphasis>NOT</emphasis> the address

1738 <application>Privoxy</application> to determine the IP address of the
1739 ultimate target (that's often what gateways are used for).
1742 You should prefer using IP addresses over DNS names, because the address lookups take
1743 time. All DNS names must resolve! You can <emphasis>not</emphasis> use domain patterns
1744 like <quote>*.org</quote> or partial domain names. If a DNS name resolves to multiple
1745 IP addresses, only the first one is used.
1748 Some systems allow IPv4 clients to connect to IPv6 server sockets.
1749 Then the client's IPv4 address will be translated by the system into
1750 IPv6 address space with special prefix ::ffff:0:0/96 (so called IPv4
1751 mapped IPv6 address). <application>Privoxy</application> can handle it
1752 and maps such ACL addresses automatically.

2068 Don't use SOCKS proxies.
2076 Multiple lines are OK, they are checked in sequence, and the last match wins.
2079 The difference between <literal>forward-socks4</literal> and <literal>forward-socks4a</literal>
2080 is that in the SOCKS 4A protocol, the DNS resolution of the target hostname happens on the SOCKS
2081 server, while in SOCKS 4 it happens locally.
2084 With <literal>forward-socks5</literal> the DNS resolution will happen on the remote server as well.
2087 <literal>forward-socks5t</literal> works like vanilla <literal>forward-socks5</literal> but
2088 lets &my-app; additionally use Tor-specific SOCKS extensions. Currently the only supported
2089 SOCKS extension is optimistic data which can reduce the latency for the first request made
2090 on a newly created connection.
2093 <replaceable class="parameter">socks_proxy</replaceable> and

2096 <ulink url="http://tools.ietf.org/html/rfc3493">RFC 3493</ulink> is
2097 implemented). To prevent clashes with the port delimiter, the whole IP
2098 address has to be put into brackets. On the other hand a <replaceable
2099 class="parameter">target_pattern</replaceable> containing an IPv6 address
2100 has to be put into angle brackets (normal brackets are reserved for
2101 regular expressions already).
2104 If <replaceable class="parameter">http_parent</replaceable> is <quote>.</quote>, then requests are not
2105 forwarded to another HTTP proxy but are made (HTTP-wise) directly to the web servers, albeit through
2111 <term>Examples:</term>
2114 From the company example.com, direct connections are made to all
2115 <quote>internal</quote> domains, but everything outbound goes through
2116 their ISP's proxy by way of example.com's corporate SOCKS 4A gateway to
2121 forward-socks4a / socks-gw.example.com:1080 www-cache.isp.example.net:8080
2122 forward .example.com .
2126 A rule that uses a SOCKS 4 gateway for all destinations but no HTTP parent looks like this:
2130 forward-socks4 / socks-gw.example.com:1080 .
2135 To chain Privoxy and Tor, both running on the same system, you would use
2140 forward-socks5 / 127.0.0.1:9050 .
2145 The public <application>Tor</application> network can't be used to
2146 reach your local network, if you need to access local servers you
2147 therefore might want to make some exceptions:
2151 forward 192.168.*.*/ .
2153 forward 127.*.*.*/ .
2157 Unencrypted connections to systems in these address ranges will
2158 be as (un)secure as the local network is, but the alternative is that you
2159 can't reach the local network through <application>Privoxy</application>
2160 at all. Of course this may actually be desired and there is no reason
2161 to make these exceptions if you aren't sure you need them.
2164 If you also want to be able to reach servers in your local network by
2165 using their names, you will need additional exceptions that look like

2184 If you have links to multiple ISPs that provide various special content
2185 only to their subscribers, you can configure multiple <application>Privoxies</application>
2186 which have connections to the respective ISPs to act as forwarders to each other, so that
2187 <emphasis>your</emphasis> users can see the internal content of all ISPs.
2191 Assume that host-a has a PPP connection to isp-a.example.net. And host-b has a PPP connection to
2192 isp-b.example.org. Both run <application>Privoxy</application>. Their forwarding
2193 configuration can look like this:
2203 forward .isp-b.example.net host-b:8118
2214 forward .isp-a.example.org host-a:8118
2219 Now, your users can set their browser's proxy to use either
2220 host-a or host-b and be able to browse the internal content
2221 of both isp-a and isp-b.
2225 If you intend to chain <application>Privoxy</application> and
2226 <application>squid</application> locally, then chaining as
2227 <literal>browser -> squid -> privoxy</literal> is the recommended way.
2231 Assuming that <application>Privoxy</application> and <application>squid</application>
2232 run on the same box, your <application>squid</application> configuration could then look like this:
2237 # Define Privoxy as parent proxy (without ICP)
2238 cache_peer 127.0.0.1 parent 8118 7 no-query
2240 # Define ACL for protocol FTP
2243 # Do not forward FTP requests to Privoxy
2244 always_direct allow ftp
2246 # Forward all the rest to Privoxy
2247 never_direct allow all</screen>
2251 You would then need to change your browser's proxy settings to <application>squid</application>'s address and port.
2252 Squid normally uses port 3128. If unsure consult <literal>http_port</literal> in <filename>squid.conf</filename>.
2256 You could just as well decide to only forward requests you suspect
2257 of leading to Windows executables through a virus-scanning parent proxy,
2258 say, on <literal>antivir.example.com</literal>, port 8010:
2264 forward /.*\.(exe|com|dll|zip)$ antivir.example.com:8010</screen>

2308 The connection might have failed because of a DNS timeout in which case a retry makes sense,
2309 but it might also have failed because the server doesn't exist or isn't reachable. In this

2313 Note that in the context of this option, <quote>forwarded connections</quote> includes all connections
2314 that Privoxy forwards through other proxies. This option is not limited to the HTTP CONNECT method.
2317 Only use this option, if you are getting lots of forwarding-related error messages

2556 Connections are not kept alive.
2564 This option allows clients to keep the connection to &my-app;
2565 alive. If the server supports it, &my-app; will keep
2566 the connection to the server alive as well. Under certain
2567 circumstances this may result in speed-ups.
2570 By default, &my-app; will close the connection to the server if
2571 the client connection gets closed, or if the specified timeout
2572 has been reached without a new request coming in. This behaviour
2573 can be changed with the <ulink
2574 url="#CONNECTION-SHARING">connection-sharing</ulink> option.
2577 This option has no effect if <application>Privoxy</application>
2578 has been compiled without keep-alive support.
2581 Note that a timeout of five seconds as used in the default
2582 configuration file significantly decreases the number of
2583 connections that will be reused. The value is used because
2584 some browsers limit the number of connections they open to
2585 a single host and apply the same limit to proxies. This can
2586 result in a single website <quote>grabbing</quote> all the
2587 connections the browser allows, which means connections to
2588 other websites can't be opened until the connections currently
2592 Several users have reported this as a Privoxy bug, so the
2593 default value has been reduced. Consider increasing it to
2594 300 seconds or even more if you think your browser can handle
2595 it. If your browser appears to be hanging, it probably can't.

2640 If Privoxy receives more than one request at once, it terminates the
2641 client connection after serving the first one.
2649 &my-app; currently doesn't pipeline outgoing requests,
2650 thus allowing pipelining on the client connection is not
2651 guaranteed to improve the performance.
2654 By default &my-app; tries to discourage clients from pipelining
2655 by discarding aggressively pipelined requests, which forces the
2656 client to resend them through a new connection.
2659 This option lets &my-app; tolerate pipelining. Whether or not
2660 that improves performance mainly depends on the client configuration.
2663 This options is new and should be considered experimental.

2705 <term>Effect if unset:</term>
2708 Connections for which the server didn't specify the keep-alive
2709 timeout are not reused.
2717 Enabling this option significantly increases the number of connections
2718 that are reused, provided the <ulink
2719 url="#KEEP-ALIVE-TIMEOUT">keep-alive-timeout</ulink> option
2723 While it also increases the number of connections problems
2724 when &my-app; tries to reuse a connection that already has
2725 been closed on the server side, or is closed while &my-app;
2726 is trying to reuse it, this should only be a problem if it
2727 happens for the first request sent by the client. If it happens
2728 for requests on reused client connections, &my-app; will simply
2729 close the connection and the client is supposed to retry the
2730 request without bothering the user.

2798 This option has no effect if <application>Privoxy</application>
2799 has been compiled without keep-alive support, or if it's disabled.
2807 Note that reusing connections doesn't necessary cause speedups.
2808 There are also a few privacy implications you should be aware of.
2811 If this option is effective, outgoing connections are shared between
2812 clients (if there are more than one) and closing the browser that initiated
2813 the outgoing connection does no longer affect the connection between &my-app;
2814 and the server unless the client's request hasn't been completed yet.
2817 If the outgoing connection is idle, it will not be closed until either
2818 <application>Privoxy's</application> or the server's timeout is reached.
2819 While it's open, the server knows that the system running &my-app; is still
2823 If there are more than one client (maybe even belonging to multiple users),
2824 they will be able to reuse each others connections. This is potentially
2825 dangerous in case of authentication schemes like NTLM where only the
2826 connection is authenticated, instead of requiring authentication for
2830 If there is only a single client, and if said client can keep connections
2831 alive on its own, enabling this option has next to no effect. If the client
2832 doesn't support connection keep-alive, enabling this option may make sense
2833 as it allows &my-app; to keep outgoing connections alive even if the client
2834 itself doesn't support it.
2837 You should also be aware that enabling this option increases the likelihood
2838 of getting the "No server or forwarder data" error message, especially if you
2839 are using a slow connection to the Internet.
2842 This option should only be used by experienced users who
2843 understand the risks and can weight them against the benefits.

2944 Connections are served until a resource limit is reached.
2952 &my-app; creates one thread (or process) for every incoming client
2953 connection that isn't rejected based on the access control settings.
2956 If the system is powerful enough, &my-app; can theoretically deal with
2957 several hundred (or thousand) connections at the same time, but some
2958 operating systems enforce resource limits by shutting down offending
2959 processes and their default limits may be below the ones &my-app; would
2960 require under heavy load.
2963 Configuring &my-app; to enforce a connection limit below the thread
2964 or process limit used by the operating system makes sure this doesn't
2965 happen. Simply increasing the operating system's limit would work too,
2966 but if &my-app; isn't the only application running on the system,
2967 you may actually want to limit the resources used by &my-app;.
2970 If &my-app; is only used by a single trusted user, limiting the
2971 number of client connections is probably unnecessary. If there
2972 are multiple possibly untrusted users you probably still want to
2973 additionally use a packet filter to limit the maximal number of
2974 incoming connections per client. Otherwise a malicious user could
2975 intentionally create a high number of connections to prevent other
2976 users from using &my-app;.
2979 Obviously using this option only makes sense if you choose a limit
2980 below the one enforced by the operating system.

3110 Compressing buffered content is mainly useful if Privoxy and the
3111 client are running on different systems. If they are running on the
3112 same system, enabling compression is likely to slow things down.
3113 If you didn't measure otherwise, you should assume that it does
3114 and keep this option disabled.
3117 Privoxy will not compress buffered content below a certain length.

3126 <sect3 renderas="sect4" id="compression-level"><title>compression-level</title>
3129 <term>Specifies:</term>
3132 The compression level that is passed to the zlib library when compressing buffered content.
3137 <term>Type of value:</term>
3140 <replaceable>Positive number ranging from 0 to 9.</replaceable>
3145 <term>Default value:</term>
3154 Compressing the data more takes usually longer than compressing
3155 it less or not compressing it at all. Which level is best depends
3156 on the connection between Privoxy and the client. If you can't
3157 be bothered to benchmark it for yourself, you should stick with
3158 the default and keep compression disabled.
3161 If compression is disabled, the compression level is irrelevant.
3166 <term>Examples:</term>
3170 # Best speed (compared to the other levels)
3174 # No compression. Only useful for testing as the added header
3175 # slightly increases the amount of data that has to be sent.
3176 # If your benchmark shows that using this compression level
3177 # is superior to using no compression at all, the benchmark
3178 # is likely to be flawed.

3189 <sect3 renderas="sect4" id="client-header-order"><title>client-header-order</title>
3192 <term>Specifies:</term>
3195 The order in which client headers are sorted before forwarding them.
3200 <term>Type of value:</term>
3203 <replaceable>Client header names delimited by spaces or tabs</replaceable>
3208 <term>Default value:</term>
3217 By default &my-app; leaves the client headers in the order they
3218 were sent by the client. Headers are modified in-place, new headers
3219 are added at the end of the already existing headers.
3222 The header order can be used to fingerprint client requests
3223 independently of other headers like the User-Agent.
3226 This directive allows to sort the headers differently to better
3227 mimic a different User-Agent. Client headers will be emitted
3228 in the order given, headers whose name isn't explicitly specified
3229 are added at the end.
3232 Note that sorting headers in an uncommon way will make fingerprinting
3233 actually easier. Encrypted headers are not affected by this directive.
