I have a session array variable that stores the name(ID) of the form
and a time stamp of when the form was created (this ID and time stamp
is POST hidden on the form as well.) If I get a POSTed form I check
the POSTED ID and time stamp with the Session value, if they match it
is a valid update (if the from is valid and action taken I end by
erasing the the session ID/timestamp value.)
If the from POST and session do not match it is an unregistered POST
and automatically headers back to a previous menu.
This saves from errors of opening multiple windows as well as
resubmission when using the back button.
