I'm assuming that you're using a RequestDispatcher to forward the
request off. My question is why don't you use a forward response
to the web client? Do something like this:
String targetUri = genUri( request );
response.sendRedirect( targetUri );
Where the "genUri" would create the uri for the redirect. You
could put whatever you want in the uri and do whatever filtering
you want to do. Since with a redirect you're not passing the
same request object around (unlike the RequestDispater.forward)
it seems like it'd solve your problem.
