Barracuda as a drop in for Enhydra App

I'm in the process of switching a production web app from Enhydra
SuperServlet arch to Barracuda.
Now a lot of external app point to services provided by this enhydra app
with formatted URL like:
http://myserver.org/enhydraServlet.po?param1=value1&param2=value2

So i need a way to replace/forward this request directly to the
equivalent new URL which then will be handled by barracuda event system,
which is a good way to achieve this !?

There's a way to have barracuda process as event also non .event url ?!
(i admit i only try changing the relative parameter on web.xml file...)

Regards.
