Warning: Page Expired question

hey im making a site with php/mysql and i have many searches on it. after you search, it returns the results and prints them as links, and when you click those links it takes you to a profile of that specific store.

however, after you hit back on ie, you get the warning page expired. i know that this is because it is trying to run through the query again using the same value as before, but is there anything i can so that it doesnt give that warning? i know that if you refresh the page with the warning, it will tell you that will be resending data, and if you hit 'retry' it will work fine.

im using mozilla so immediately upon hitting back (unlike in windoze which takes a click and gives no warning) i get the 'info in cache, do you wish to post?' so there arent any issues

just trying to please a client

thanks for all help,
kevin

Change the Method of the form to Get from Post. That way people are also able to bookmark searches they have done.
