Email me if you have one that you would like to see added in by default. Four environmental variables are currently added to environmental namespace for Layout and Header files. They represent the parsed information that made up the original request. I personally hate them. Ok, what has been discovered thus far is that using any of the Header tags will break framesets.
Layouts seem to work fine though.
If any anyone has had any better luck mail me . As of version 0.9 I began to test support for the proxy module. Yes, all handlers use fnmatch regular expressions. Look at your system's main pages to determine syntax. You can speficy URI that are to be ignored by using the LayoutIgnoreURI directive.
