# Purpose : Rules to process the content of web pages
#
#
# Syntax:
#
-# Filters start with a line "FILTER: name description". They are then referrable
-# from the actionsfile with +filter{name}
+# 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 delimter as you see fit.
+# Note that you are free to choose the delimiter as you see fit.
#
# Note2: In addidion 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.
