let's say the Application gateway receives a request <http://contoso.com/images> and is configured to forward that to backendserver.contoso.com. Using a path based routing rule (`/images/*` for example). 

I want the application gateway not to retain the `/images` path in the request URL. I need this to be truncated, in which case the request will simply be <http://contoso.com/>. Any path after the `/images` will remain intact though.

Is it possible? Any help/clue is greatly appreciated.
