# Syntax:
#
# 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.
#
# quoting.
#
# 'D' (Dynamic) allows the use of variables. Supported variables are:
-# $host, $origin (the IP address the request came from), $path and $url.
+# $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
# 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.
