I think this will work.


when they post the form issue a redirect


(use a fixed pitch font or the following won't make much sense)

user posts automatic user navigates
form -----> redirect ------> thankyou --------> further
page page

when the user goes back from the "further" page they'll hit the
thankyou page (which was got by the redirect so no data to post)
(back again gets them to the form.)


Bye.
