Erasing a QFC container session upon a re-visit

Hi, I'd like to clear the QFC container session if the user goes back to the PHP page later on. Is there a recommended/clean way to test and erase the session upon a user coming back to a QFC based page? My initial thoughts where to check the HTTP referer and just unset the container in the session if it was not equal to the script itself. Is there a neater way?
