Rewrite link but keep old physical path.

Hello everyone,

Is there any way in which I can rewrite the links on my site, but keep the old physical path. 

Example :

My link : XXXXAA-BBBB01.php

What I want it to look like  : BBBB01.php

I repeat, I have set up the rewrite, but I want the content to load from XXXXAA-BBBB01.php.

Is this possible?

Thank you.
