Since the browser has no clue that the request was forwarded, this cannot
be done without using a redirect instead of a forward. This costs you so
much (performance loss, inability to use request attributes) that it's not
worth it.
You're much better off training your users that the location bar is
totally irrelevant in webapps. For stubborn people who don't get the
message, you can play nasty games like use a single-frame frameset (so
that the location bar never changes), or open a window with no location
bar -- but web apps are not the same thing as web sites.
