A generic way to handle requests apart an ordinary Filter

Hi All,

What is the best way to handle multiple urls in a generic way?

It should be able to handle urls like :

http://somehost/somecategory/somesubcategory/page1.html

http://somehost/somecategory/somesubcategory/pageN.html

The only way I can think of is a Filter. But by definition a filter should alter some headers or inject some information and in my case I need to generate the whole response. 

Thanks in advance,

Yura.
