- #################################################################################
- #
- # 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, $listen-address, $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.
