It's happening because you're requesting the page again, using the same POST parameters that were used to request it the first time.

To fix it: either check for a page refresh in your code and don't do the insert in that event, or set a cookie the first time, and then don't do the insert again if the cookie is there. The cookie could either have a fixed duration (say 30 minutes), or it could be a session cookie, which would last until the users closes the browser.
