Allowing refresh without form processing?

Hey, I have a page where I'd like to allow the client to use their refresh button. The only problem with this is, when they submit a form that's on the page, it is parsed by the same page. So if they hit refresh, the same information will be submitted twice (or more). How can I "clear" out any knowledge that a form was submitted? I've tried adding unset ($HTTP_POST_VARS); to the bottom of the page but that didn't do anything for it... Any other ideas? BTW, I'm asking this because the form uses a db to process and I'm unsure if that may be the issue or not...
