I am sure that this is a problem that many more experienced users here have encountered:
After clicking a submit button my form updates a database. I don't want this action to be possible more than once, so I disable the submuit button in the click event. However. if the user clicks the page refresh button in his browser, I get a dialog that
says "The page that you're looking for used information that you entered. Returning to that page might cause any action that you took to be repeated. Do you want to continue?" If the user clicks "Continue" the action is repeated.
How do I prevent this? It would seem to involve me doing some kind of 'flush' action on the previous state.
Many thanks.
