This will not stop the user from hitting the "Back" button and refreshing
the form... What I do (and it works flawlessly) is to have a serial number
stored in the session data. This serial number, mirrored in form data as a
hidden field, is incremented with each klick the script receives. Thus the
code handling script input is able to determine if the form it just
received is the last form it generated (serial number matches), or is
outdated (serial number mismatches), for what reason ever, be it a refresh
or the user stepping back and resubmitting.
