This file contains all the config file comments and options. It used to
|
||
|
build both the user-manual config sections, and all of config (yes, the main
|
||
|
config file) itself.
|
||
|
|
||
|
Rationale: This is broken up into two files since a file with a prolog
|
||
|
(DTD, etc) cannot be sourced as a secondary file. config.sgml is basically
|
||
|
a wrapper for this file.
|
||
|
|
||
|
IMPORTANT:
|
||
|
|
||
|
OPTIONS: The actual options are included in this file and prefixed with
|
||
|
'@@', and processed by the Makefile to strip the '@@'. Default options
|
||
|
that should appear commented out should be listed as: '@@#OPTION'.
|
||
|
Otherwise, as '@@OPTION'. Example:
|
||
|
|
||
|
@@listen-address 127.0.0.1:8118
|
||
|
|
||
|
The Makefile does significant other processing too. The final results
|
||
|
should be checked to make sure that the perl processing does not
|
||
|
fubar something!!! Makefile processing requires w3m, fmt (shell line
|
||
|
formatter), and perl.
|
||
|
|
||
|
|
||
|
This file is included into:
|
||
|
|
||
|
user-manual.sgml
|
||
|
config (the actual Privoxy config file)

Again, the main configuration file is named <filename>config</filename> on
|

|
Linux/Unix/BSD and OS/2, and <filename>config.txt</filename> on Windows.
|

Configuration lines consist of an initial keyword followed by a list of
|

values, all separated by whitespace (any number of spaces or tabs). For
|
||
|
example:

Assigns the value <literal>/etc/privoxy</literal> to the option

=============== <!-- fuck this madness --></literallayout>

This file holds Privoxy's main configuration. Privoxy detects
|
||
|
configuration changes automatically, so you don't have to restart it
|
||
|
unless you want to load a different configuration file.
|
||
|
</para>
|
||
|
<para>
|
||
|
The configuration will be reloaded with the first request after the
|
||
|
change was done, this request itself will still use the old configuration,
|
||
|
though. In other words: it takes two requests before you see the result of
|
||
|
your changes. Requests that are dropped due to ACL don't trigger reloads.
|
||
|
</para>
|
||
|
<para>
|
||
|
When starting Privoxy on Unix systems, give the location of this
|
||
|
file as last argument. On Windows systems, Privoxy will look for
|
||
|
this file with the name 'config.txt' in the current working directory
|
||
|
of the Privoxy process.

II. FORMAT OF THE CONFIGURATION FILE
|
||
|
====================================</literallayout>
|
||
|
</para>
|
||
|
<para>
|
||
|
Configuration lines consist of an initial keyword followed by a list
|
||
|
of values, all separated by whitespace (any number of spaces or
|
||
|
tabs). For example,
|
||
|
</para>
|
||
|
<para>
|
||
|
actionsfile default.action
|
||
|
</para>
|
||
|
<para>
|
||
|
Indicates that the actionsfile is named 'default.action'.
|
||
|
</para>
|
||
|
<para>
|
||
|
The '#' indicates a comment. Any part of a line following a '#' is
|
||
|
ignored, except if the '#' is preceded by a '\'.
|
||
|
</para>
|
||
|
<para>
|
||
|
Thus, by placing a # at the start of an existing configuration line,
|
||
|
you can make it a comment and it will be treated as if it weren't there.
|
||
|
This is called "commenting out" an option and can be useful. Removing
|
||
|
the # again is called "uncommenting".
|
||
|
</para>
|
||
|
<para>
|
||
|
Note that commenting out an option and leaving it at its default
|
||
|
are two completely different things! Most options behave very
|
||
|
differently when unset. See the "Effect if unset" explanation
|
||
|
in each option's description for details.
|
||
|
</para>
|
||
|
<para>
|
||
|
Long lines can be continued on the next line by using a `\' as
|
||
|
the last character.

||
|

The User Manual URI is the single best source of information on
|
||
|
<application>Privoxy</application>, and is used for help links from some
|
||
|
of the internal CGI pages. The manual itself is normally packaged with the
|
||
|
binary distributions, so you probably want to set this to a locally
|
||
|
installed copy.

<para>

The User Manual is then available to anyone with access to
|

|
<application>Privoxy</application>, by following the built-in URL:
|

|
<literal>http://config.privoxy.org/user-manual/</literal>

The logfile is where all logging and error messages are written. The level
|
||
|
of detail and number of messages are set with the <literal>debug</literal>
|
||
|
option (see below). The logfile can be useful for tracking down a problem with
|
||
|
<application>Privoxy</application> (e.g., it's not blocking an ad you
|
||
|
think it should block) and it can help you to monitor what your browser
|
||
|
is doing.
|
||
|
</para>
|
||
|
<para>
|
||
|
Depending on the debug options below, the logfile may be a privacy risk
|
||
|
if third parties can get access to it. As most users will never look
|
||
|
at it, <application>Privoxy</application> 3.0.7 and later only log fatal
|
||
|
errors by default.
|
||
|
</para>
|

<para>

For most troubleshooting purposes, you will have to change that,
|
||
|
please refer to the debugging section for details.

</para>
|

|
<para>
|

Your logfile will grow indefinitely, and you will probably want to
|
||
|
periodically remove it. On Unix systems, you can do this with a cron job
|
||
|
(see <quote>man cron</quote>). For Red Hat based Linux distributions, a
|
||
|
<command>logrotate</command> script has been included.

The trust mechanism is an experimental feature for building white-lists and should
|

|
be used with care. It is <emphasis>NOT</emphasis> recommended for the casual user.
|

|
</para>
|

<para>
|

If you specify a trust file, <application>Privoxy</application> will only allow
|
||
|
access to sites that are specified in the trustfile. Sites can be listed
|
||
|
in one of two ways:
|
||
|
</para>
|
||
|
<para>
|
||
|
Prepending a <literal>~</literal> character limits access to this site
|
||
|
only (and any sub-paths within this site), e.g.
|
||
|
<literal>~www.example.com</literal> allows access to
|
||
|
<literal>~www.example.com/features/news.html</literal>, etc.
|
||
|
</para>
|
||
|
<para>
|
||
|
Or, you can designate sites as <emphasis>trusted referrers</emphasis>, by
|
||
|
prepending the name with a <literal>+</literal> character. The effect is that
|
||
|
access to untrusted sites will be granted -- but only if a link from this
|
||
|
trusted referrer was used to get there. The link target will then be added
|
||
|
to the <quote>trustfile</quote> so that future, direct accesses will be
|
||
|
granted. Sites added via this mechanism do not become trusted referrers
|
||
|
themselves (i.e. they are added with a <literal>~</literal> designation).
|
||
|
There is a limit of 512 such entries, after which new entries will not be
|
||
|
made.
|
||
|
</para>
|
||
|
<para>
|
||
|
If you use the <literal>+</literal> operator in the trust file, it may grow
|
||
|
considerably over time.
|
||
|
</para>
|
||
|
<para>
|

It is recommended that <application>Privoxy</application> be compiled with

<para>

A debug level of 1 is informative because it will show you each request
|
||
|
as it happens. <emphasis>1, 4096 and 8192 are recommended</emphasis>
|
||
|
so that you will notice when things go wrong. The other levels are

|
probably only of interest if you are hunting down a specific problem.
|

They can produce a hell of an output (especially 16).

<para>
|
||
|
<application>Privoxy</application> is mainly used to block and filter
|
||
|
requests as a service to the user, for example to block ads and other
|
||
|
junk that clogs the pipes. <application>Privoxy's</application> configuration
|
||
|
isn't perfect and sometimes innocent pages are blocked. In this situation it
|
||
|
makes sense to allow the user to enforce the request and have
|
||
|
<application>Privoxy</application> ignore the block.
|
||
|
</para>
|
||
|
<para>
|
||
|
In the default configuration <application>Privoxy's</application>
|
||
|
<quote>Blocked</quote> page contains a <quote>go there anyway</quote>
|
||
|
link to adds a special string (the force prefix) to the request URL.
|
||
|
If that link is used, <application>Privoxy</application> will
|
||
|
detect the force prefix, remove it again and let the request pass.
|
||
|
</para>
|
||
|
<para>
|
||
|
Of course <application>Privoxy</application> can also be used to enforce
|
||
|
a network policy. In that case the user obviously should not be able to
|
||
|
bypass any blocks, and that's what the <quote>enforce-blocks</quote>
|
||
|
option is for. If it's enabled, <application>Privoxy</application> hides
|
||
|
the <quote>go there anyway</quote> link. If the user adds the force
|
||
|
prefix by hand, it will not be accepted and the circumvention attempt
|
||
|
is logged.

For content filtering, i.e. the <literal>+filter</literal> and

|
<literal>+deanimate-gif</literal> actions, it is necessary that
|
||
|
<application>Privoxy</application> buffers the entire document body.
|
||
|
This can be potentially dangerous, since a server could just keep sending
|
||
|
data indefinitely and wait for your RAM to exhaust -- with nasty consequences.
|
||

This feature allows routing of HTTP requests through a chain of
|
||
|
multiple proxies.
|
||
|
</para>
|
||
|
<para>
|
||
|
Forwarding can be used to chain Privoxy with a caching proxy to speed
|
||
|
up browsing. Using a parent proxy may also be necessary if the machine
|
||
|
that <application>Privoxy</application> runs on has no direct Internet access.
|
||
|
</para>
|
||
|
<para>
|
||
|
Note that parent proxies can severely decrease your privacy level.
|
||
|
For example a parent proxy could add your IP address to the request
|
||
|
headers and if it's a caching proxy it may add the <quote>Etag</quote>
|
||
|
header to revalidation requests again, even though you configured Privoxy
|
||
|
to remove it. It may also ignore Privoxy's header time randomization and use the
|
||
|
original values which could be used by the server as cookie replacement
|
||
|
to track your steps between visits.
|
||
|
</para>
|
||
|
|
||
|
<para>

Also specified here are SOCKS proxies. <application>Privoxy</application>

The public <application>Tor</application> network can't be used to

<para>
|

Unencrypted connections to systems in these address ranges will

|
be as (un)secure as the local network is, but the alternative is that you

|
can't reach the local network through <application>Privoxy</application>
|
||
|
at all. Of course this may actually be desired and there is no reason

<replaceable class="parameter">forwarded-connect-retries</replaceable> is mainly interesting

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

|
case the retry will just delay the appearance of Privoxy's error message.

Only use this option, if you are getting lots of forwarding-related error messages

logfile from time to time, to see how many retries are usually needed.

<application>Privoxy's</application> CGI forms can lead to

rather long URLs. This isn't a problem as far as the HTTP

to divide big forms into smaller ones to keep the URL length down.
