DESCRIPTION

ASP4::TransHandler is a utility class that helps module authors take advantage of the ASP4 configuration without actually doing any of the work.

RequestFilters vs TransHandlers

The difference between TransHandlers and ASP4::RequestFilters is that within a RequestFilter, you have access to all of the normal ASP objects ($Request, $Response, $Session, etc).

In a TransHandler, you only have access to the Apache2::RequestRec $r and the ASP4::Config (and only then if you load it up yourself via ASP4::ConfigLoader.

NOTE: - TransHandlers are configured in the httpd.conf and are only executed in a real Apache2 httpd environment. They are not executed during testing or via ASP4::API.

TransHandlers are a handy way of jumping into "normal" mod_perl handler mode without losing access to your web application's config.
