Hello Raghu,

Maybe a resource init hander could help you. Basically, it allows to 
read a different resource than the one shown in the URI. And this is 
what actually is what you want.

I have attached a few slides from a presentation I made during the 
OpenCms Days 2009 explaining the basic concept and a little example.

Hope this helps.
