A simple thing to do is to put an md5 hash into the POST data, then only do the insert if that md5 hash isn't already "used" when they hit refresh.
Thank you for your responses. One question: If I were to use the md5 hash method, what would be the best way to store used hashes? In a database? In a temporary file kinda thing? Thanks again.
