CGI form repost from browser--how to prevent?

[Scherer, Bill]

Chris - 

Try tracking the state in J(ava)Script on the client side.  When 
the user performs an action leading to a form submission, set 
the flag just prior to the submit() call.  Check the flag before 
that. If it's in a submitted state, ignore the user request, or 
inform them that a submit is in progress or whatever...
