I've seen this happen before, where I was adding entries to a database when a user navigated to a certain page from a link. The way I solved it was to add a timestamp and check to see if an exact duplicate entry had been made within the last n seconds before adding it. You could add a time value to the session and check against this before unsetting the session?
