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'.

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

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

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

913 If you specify a trust file, <application>Privoxy</application> will only allow
914 access to sites that are specified in the trustfile. Sites can be listed
918 Prepending a <literal>~</literal> character limits access to this site
919 only (and any sub-paths within this site), e.g.
920 <literal>~www.example.com</literal> allows access to

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

1222 recommended for home users who run <application>Privoxy</application> on
1223 the same machine as their browser.
1231 You will need to configure your browser(s) to this proxy address and port.
1234 If you already have another service running on port 8118, or if you want to
1235 serve requests from other machines (e.g. on your local network) as well, you
1236 will need to override the default.

1246 If a hostname is used instead of an IP address, <application>Privoxy</application>
1247 will try to resolve it to an IP address and if there are multiple, use the first
1251 If the address for the hostname isn't already known on the system

1261 IPv6 addresses containing colons have to be quoted by brackets.
1262 They can only be used if <application>Privoxy</application> has
1263 been compiled with IPv6 support. If you aren't sure if your version
1264 supports it, have a look at
1265 <literal>http://config.privoxy.org/show-status</literal>.
1268 Some operating systems will prefer IPv6 to IPv4 addresses even if the
1269 system has no IPv6 connectivity which is usually not expected by the user.
1270 Some even rely on DNS to resolve localhost which mean the "localhost" address
1271 used may not actually be local.
1274 It is therefore recommended to explicitly configure the intended IP address
1275 instead of relying on the operating system, unless there's a strong reason not to.
1278 If you leave out the address, <application>Privoxy</application> will bind to all
1279 IPv4 interfaces (addresses) on your machine and may become reachable from the
1280 Internet and/or the local network. Be aware that some GNU/Linux distributions
1281 modify that behaviour without updating the documentation. Check for non-standard
1282 patches if your <application>Privoxy</application> version behaves differently.
1285 If you configure <application>Privoxy</application> to be reachable from the

1287 (ACL's, see below), and/or a firewall.

1739 You should prefer using IP addresses over DNS names, because the address lookups take
1740 time. All DNS names must resolve! You can <emphasis>not</emphasis> use domain patterns

1742 IP addresses, only the first one is used.
1745 Some systems allow IPv4 clients to connect to IPv6 server sockets.
1746 Then the client's IPv4 address will be translated by the system into
1747 IPv6 address space with special prefix ::ffff:0:0/96 (so called IPv4
1748 mapped IPv6 address). <application>Privoxy</application> can handle it
1749 and maps such ACL addresses automatically.

2137 The difference between <literal>forward-socks4</literal> and <literal>forward-socks4a</literal>
2138 is that in the SOCKS 4A protocol, the DNS resolution of the target hostname happens on the SOCKS
2139 server, while in SOCKS 4 it happens locally.
2142 With <literal>forward-socks5</literal> the DNS resolution will happen on the remote server as well.
2145 <literal>forward-socks5t</literal> works like vanilla <literal>forward-socks5</literal> but
2146 lets &my-app; additionally use Tor-specific SOCKS extensions. Currently the only supported
2147 SOCKS extension is optimistic data which can reduce the latency for the first request made

2162 If <replaceable class="parameter">http_parent</replaceable> is <quote>.</quote>, then requests are not
2163 forwarded to another HTTP proxy but are made (HTTP-wise) directly to the web servers, albeit through
2169 <term>Examples:</term>
2172 From the company example.com, direct connections are made to all
2173 <quote>internal</quote> domains, but everything outbound goes through
2174 their ISP's proxy by way of example.com's corporate SOCKS 4A gateway to
2179 forward-socks4a / socks-gw.example.com:1080 www-cache.isp.example.net:8080
2180 forward .example.com .
2184 A rule that uses a SOCKS 4 gateway for all destinations but no HTTP parent looks like this:
2188 forward-socks4 / socks-gw.example.com:1080 .
2193 To chain Privoxy and Tor, both running on the same system, you would use
2198 forward-socks5 / 127.0.0.1:9050 .
2203 The public <application>Tor</application> network can't be used to
2204 reach your local network, if you need to access local servers you
2205 therefore might want to make some exceptions:
2209 forward 192.168.*.*/ .
2211 forward 127.*.*.*/ .
2215 Unencrypted connections to systems in these address ranges will
2216 be as (un)secure as the local network is, but the alternative is that you
2217 can't reach the local network through <application>Privoxy</application>
2218 at all. Of course this may actually be desired and there is no reason
2219 to make these exceptions if you aren't sure you need them.
2222 If you also want to be able to reach servers in your local network by
2223 using their names, you will need additional exceptions that look like

2242 If you have links to multiple ISPs that provide various special content
2243 only to their subscribers, you can configure multiple <application>Privoxies</application>
2244 which have connections to the respective ISPs to act as forwarders to each other, so that
2245 <emphasis>your</emphasis> users can see the internal content of all ISPs.
2249 Assume that host-a has a PPP connection to isp-a.example.net. And host-b has a PPP connection to
2250 isp-b.example.org. Both run <application>Privoxy</application>. Their forwarding
2251 configuration can look like this:
2261 forward .isp-b.example.net host-b:8118
2272 forward .isp-a.example.org host-a:8118
2277 Now, your users can set their browser's proxy to use either
2278 host-a or host-b and be able to browse the internal content
2279 of both isp-a and isp-b.
2283 If you intend to chain <application>Privoxy</application> and
2284 <application>squid</application> locally, then chaining as
2285 <literal>browser -> squid -> privoxy</literal> is the recommended way.
2289 Assuming that <application>Privoxy</application> and <application>squid</application>
2290 run on the same box, your <application>squid</application> configuration could then look like this:
2295 # Define Privoxy as parent proxy (without ICP)
2296 cache_peer 127.0.0.1 parent 8118 7 no-query
2298 # Define ACL for protocol FTP
2301 # Do not forward FTP requests to Privoxy
2302 always_direct allow ftp
2304 # Forward all the rest to Privoxy
2305 never_direct allow all</screen>
2309 You would then need to change your browser's proxy settings to <application>squid</application>'s address and port.
2310 Squid normally uses port 3128. If unsure consult <literal>http_port</literal> in <filename>squid.conf</filename>.
2314 You could just as well decide to only forward requests you suspect
2315 of leading to Windows executables through a virus-scanning parent proxy,
2316 say, on <literal>antivir.example.com</literal>, port 8010:
2322 forward /.*\.(exe|com|dll|zip)$ antivir.example.com:8010</screen>

2614 Connections are not kept alive.
2622 This option allows clients to keep the connection to &my-app;
2623 alive. If the server supports it, &my-app; will keep
2624 the connection to the server alive as well. Under certain
2625 circumstances this may result in speed-ups.
2628 By default, &my-app; will close the connection to the server if
2629 the client connection gets closed, or if the specified timeout
2630 has been reached without a new request coming in. This behaviour
2631 can be changed with the <ulink
2632 url="#CONNECTION-SHARING">connection-sharing</ulink> option.
2635 This option has no effect if <application>Privoxy</application>
2636 has been compiled without keep-alive support.
2639 Note that a timeout of five seconds as used in the default
2640 configuration file significantly decreases the number of
2641 connections that will be reused. The value is used because
2642 some browsers limit the number of connections they open to
2643 a single host and apply the same limit to proxies. This can
2644 result in a single website <quote>grabbing</quote> all the
2645 connections the browser allows, which means connections to
2646 other websites can't be opened until the connections currently
2650 Several users have reported this as a Privoxy bug, so the
2651 default value has been reduced. Consider increasing it to
2652 300 seconds or even more if you think your browser can handle
2653 it. If your browser appears to be hanging, it probably can't.

2698 If Privoxy receives more than one request at once, it terminates the

2707 &my-app; currently doesn't pipeline outgoing requests,
2708 thus allowing pipelining on the client connection is not
2709 guaranteed to improve the performance.
2712 By default &my-app; tries to discourage clients from pipelining
2713 by discarding aggressively pipelined requests, which forces the
2714 client to resend them through a new connection.
2717 This option lets &my-app; tolerate pipelining. Whether or not
2718 that improves performance mainly depends on the client configuration.
2721 If you are seeing problems with pages not properly loading,
2722 disabling this option could work around the problem.

2767 Connections for which the server didn't specify the keep-alive
2768 timeout are not reused.
2776 Enabling this option significantly increases the number of connections
2777 that are reused, provided the <ulink
2778 url="#KEEP-ALIVE-TIMEOUT">keep-alive-timeout</ulink> option
2782 While it also increases the number of connections problems
2783 when &my-app; tries to reuse a connection that already has
2784 been closed on the server side, or is closed while &my-app;
2785 is trying to reuse it, this should only be a problem if it
2786 happens for the first request sent by the client. If it happens
2787 for requests on reused client connections, &my-app; will simply
2788 close the connection and the client is supposed to retry the
2789 request without bothering the user.

2858 has been compiled without keep-alive support, or if it's disabled.
2866 Note that reusing connections doesn't necessary cause speedups.
2867 There are also a few privacy implications you should be aware of.
2870 If this option is effective, outgoing connections are shared between
2871 clients (if there are more than one) and closing the browser that initiated
2872 the outgoing connection does no longer affect the connection between &my-app;
2873 and the server unless the client's request hasn't been completed yet.
2876 If the outgoing connection is idle, it will not be closed until either
2877 <application>Privoxy's</application> or the server's timeout is reached.
2878 While it's open, the server knows that the system running &my-app; is still
2882 If there are more than one client (maybe even belonging to multiple users),
2883 they will be able to reuse each others connections. This is potentially
2884 dangerous in case of authentication schemes like NTLM where only the
2885 connection is authenticated, instead of requiring authentication for
2889 If there is only a single client, and if said client can keep connections
2890 alive on its own, enabling this option has next to no effect. If the client
2891 doesn't support connection keep-alive, enabling this option may make sense
2892 as it allows &my-app; to keep outgoing connections alive even if the client
2893 itself doesn't support it.
2896 You should also be aware that enabling this option increases the likelihood
2897 of getting the "No server or forwarder data" error message, especially if you
2898 are using a slow connection to the Internet.
2901 This option should only be used by experienced users who
2902 understand the risks and can weight them against the benefits.

3003 Connections are served until a resource limit is reached.
3011 &my-app; creates one thread (or process) for every incoming client
3012 connection that isn't rejected based on the access control settings.
3015 If the system is powerful enough, &my-app; can theoretically deal with
3016 several hundred (or thousand) connections at the same time, but some
3017 operating systems enforce resource limits by shutting down offending
3018 processes and their default limits may be below the ones &my-app; would
3019 require under heavy load.
3022 Configuring &my-app; to enforce a connection limit below the thread
3023 or process limit used by the operating system makes sure this doesn't
3024 happen. Simply increasing the operating system's limit would work too,
3025 but if &my-app; isn't the only application running on the system,
3026 you may actually want to limit the resources used by &my-app;.
3029 If &my-app; is only used by a single trusted user, limiting the
3030 number of client connections is probably unnecessary. If there
3031 are multiple possibly untrusted users you probably still want to
3032 additionally use a packet filter to limit the maximal number of
3033 incoming connections per client. Otherwise a malicious user could
3034 intentionally create a high number of connections to prevent other
3035 users from using &my-app;.
3038 Obviously using this option only makes sense if you choose a limit
3039 below the one enforced by the operating system.
3042 One most POSIX-compliant systems &my-app; can't properly deal with
3043 more than FD_SETSIZE file descriptors at the same time and has to reject
3044 connections if the limit is reached. This will likely change in a
3045 future version, but currently this limit can't be increased without
3046 recompiling &my-app; with a different FD_SETSIZE limit.

3098 <term>Effect if set:</term>
3101 Privoxy returns a status 200(OK) for pages blocked with +handle-as-empty-document
3102 and a status 403(Forbidden) for all other blocked pages.
3110 This is a work-around for Firefox bug 492459:
3112 Websites are no longer rendered if SSL requests for JavaScripts are blocked by a proxy.

3115 >https://bugzilla.mozilla.org/show_bug.cgi?id=492459</ulink>)
3116 As the bug has been fixed for quite some time this option should no longer
3117 be needed and will be removed in a future release. Please speak up if you
3118 have a reason why the option should be kept around.

3127 <sect3 renderas="sect4" id="enable-compression"><title>enable-compression</title>
3130 <term>Specifies:</term>
3133 Whether or not buffered content is compressed before delivery.

3146 <term>Default value:</term>
3152 <term>Effect if unset:</term>
3155 Privoxy does not compress buffered content.
3160 <term>Effect if set:</term>
3163 Privoxy compresses buffered content before delivering it to the client,
3164 provided the client supports it.
3172 This directive is only supported if Privoxy has been compiled with
3173 FEATURE_COMPRESSION, which should not to be confused with FEATURE_ZLIB.
3176 Compressing buffered content is mainly useful if Privoxy and the
3177 client are running on different systems. If they are running on the
3178 same system, enabling compression is likely to slow things down.
3179 If you didn't measure otherwise, you should assume that it does
3180 and keep this option disabled.
3183 Privoxy will not compress buffered content below a certain length.
3188 <![%config-file;[<literallayout>@@#enable-compression 1</literallayout>]]>
3192 <sect3 renderas="sect4" id="compression-level"><title>compression-level</title>
3195 <term>Specifies:</term>
3198 The compression level that is passed to the zlib library when compressing buffered content.
3203 <term>Type of value:</term>
3206 <replaceable>Positive number ranging from 0 to 9.</replaceable>
3211 <term>Default value:</term>
3220 Compressing the data more takes usually longer than compressing
3221 it less or not compressing it at all. Which level is best depends
3222 on the connection between Privoxy and the client. If you can't
3223 be bothered to benchmark it for yourself, you should stick with
3224 the default and keep compression disabled.
3227 If compression is disabled, the compression level is irrelevant.
3232 <term>Examples:</term>
3236 # Best speed (compared to the other levels)
3240 # No compression. Only useful for testing as the added header
3241 # slightly increases the amount of data that has to be sent.
3242 # If your benchmark shows that using this compression level
3243 # is superior to using no compression at all, the benchmark
3244 # is likely to be flawed.

3255 <sect3 renderas="sect4" id="client-header-order"><title>client-header-order</title>
3258 <term>Specifies:</term>
3261 The order in which client headers are sorted before forwarding them.
3266 <term>Type of value:</term>
3269 <replaceable>Client header names delimited by spaces or tabs</replaceable>
3274 <term>Default value:</term>
3283 By default &my-app; leaves the client headers in the order they
3284 were sent by the client. Headers are modified in-place, new headers
3285 are added at the end of the already existing headers.
3288 The header order can be used to fingerprint client requests
3289 independently of other headers like the User-Agent.
3292 This directive allows to sort the headers differently to better
3293 mimic a different User-Agent. Client headers will be emitted
3294 in the order given, headers whose name isn't explicitly specified
3295 are added at the end.
3298 Note that sorting headers in an uncommon way will make fingerprinting
3299 actually easier. Encrypted headers are not affected by this directive.
