Dear Michael

Thank you very much - this looks  extremely interesting.

For all: in opencms-system.xml, there are several resource handlers that 
are predefined with the possibility to configure additional handlers. A 
resource init handler is a class that responsible for mapping a 
requested URL to a resource in opencms. All handlers are called in 
sequence, which means that an additional URL scheme can be added without 
affecting existing functionality.

This looks very simple to use and quite elegant. I like this a lot.
This is exactly what I was looking for.

thanks and regards
Christian
