#
# Syntax:
#
# Generally filters start with a line like "FILTER: name description".
# They are then referrable from the actionsfile with +filter{name}
#
# FILTER marks a filter as content filter, other filter
# types are CLIENT-HEADER-FILTER, CLIENT-HEADER-TAGGER,
# SERVER-HEADER-FILTER and SERVER-HEADER-TAGGER.
#
# Inside the filters, write one Perl-Style substitution (job) per line.
# Jobs that precede the first FILTER: line are ignored.
#
# For Details see the pcrs manpage contained in this distribution.
# (and the perlre, perlop and pcre manpages)
#
# Note that you are free to choose the delimiter as you see fit.
#
# Note2: In addition to the Perl options gimsx, the following nonstandard
# options are supported:
#
# 'U' turns the default to ungreedy matching. Add ? to quantifiers to
# switch back to greedy.
#
# 'T' (trivial) prevents parsing for backreferences in the substitute.
# Use if you want to include text like '$&' in your substitute without
# quoting.
#
# 'D' (Dynamic) allows the use of variables. Supported variables are:
# $host, $origin (the IP address the request came from), $path and $url.
#
# Note that '$' is a bad choice as delimiter for dynamic filters as you
# might end up with unintended variables if you use a variable name
# directly after the delimiter. Variables will be resolved without
# escaping anything, therefore you also have to be careful not to chose
# delimiters that appear in the replacement text. For example '<' should
# be save, while '?' will sooner or later cause conflicts with $url.

# hide-tor-exit-notation: Remove the Tor exit node notation in Host and Referer headers.
#
# Note: If Privoxy and Tor are chained and Privoxy is configured to
# use socks4a, one can use http://www.example.org.foobar.exit/
# to access the host www.example.org through Tor exit node foobar.
#
# As the HTTP client isn't aware of this notation, it treats the
# whole string "www.example.org.foobar.exit" as host and uses it
# for the "Host" and "Referer" headers. From the server's point of
# view the resulting headers are invalid and can cause problems.
#
# An invalid "Referer" header can trigger "hot-linking" protections,
# an invalid "Host" header will make it impossible for the server to
# find the right vhost (several domains hosted on the same IP address).
#
# This filter removes the "foo.exit" part in those headers
# to prevent the mentioned problems. Note that it only modifies
# the HTTP headers, it doesn't make it impossible for the server
# to detect your Tor exit node based on the IP address the request is
# coming from.

# a pattern that the ressource as a whole wouldn't.
