When you forward from one servlet to another, is there a way to remove parameters from the HTTP request object? For example, you have a login servlet that after authentication forwards on to an application servlet. How do I remove the id and password input parameters from the request so they do not sent forward?
So the information is actually being sent, but access by the second servlet is denied? If so, what guarantees the security?

The Java object model, I guess. If you really don't trust another servlet in the same application, then you should do a browser-redirect instead of a forward. It's a bit slower an clumsier, but that way there is a completely different request with completely different parameters. But may I ask why you think this might be a problem? The "destination" servlet is part of the same application as the "login" one, so anything the login code can do, so can the other servlet.
