How to prevent user from refreshing sql page?

Hello Everyone,

On my ASP pages I have users tha will submit information to the next page that inserts it into a sql table. How do i keep them from clicking Refresh and having it do this process again? I hate to have a session flag to manage throughout the site. And I thought of checking what url page it is called from but there are a couple that after adding a record, it lets you do it again from the same page. I think I do this at only one place so if I had to I could change that one and then just not run it if you reload the same page.

What I was wondering is if there is any way to clear out what parameters being passed to a page once you do it so if you click refresh, they are not passed back in.

Thanks!!
