Hallo list, Answering my own request ..
> I have not found a way yet to determine the really delivered URL > instead of the user given one. I found out that the filename field in the request_rec contains the actually used PHP script. So with the use of the document root of the request I will be able construct a virtual URL as if the user directly requested the real file. Probably this is the only way to find out what PHP will be doing later with the request. Greetings -- Christoph Gröver
