Hello,

I am not sure what you can do about GET requests.  How would you know if it was
the same person clicking or multiple people behind a proxy server clicking?

As for the POST, you are generally sending the POST data to an Action to handle
form processing.  I would just add some kind of a sequence number as a hidden
value in the form, and then add that to an array in the $_SESSION to see if
that version of the form had already been processed.  If so, abort processing
(perhaps throw an error message if you use a session based error queue as I
detailed in the PHP|A article).

HTH

Jason
