Prevent parameters from being visible?

[Dave Soto]

When processing a request within a servlet, how can I prevent parameters from being visible in the address bar of the browser? I tried request.removeParameter, thinking it would remove the parameter from display, but that was not the case.
(By the way, thanks to Dave Van Even for his help on that subject. He gave me the right answer, I was just asking the wrong question.)
I'm sure this is probably a simple one.

Use POST instead of GET in your <form>
