That's what I don't understand: The second time around, I'm only
reading data that were POSTed from the form the first time, so why
does FFox warn me? I can use a transaction number to check if it's
already been submitted, and it's just the user hitting F5.

I prefer not to use the GET method because I'd rather keep the URL
clean in case users bookmark them.

OK, I'll check it out.
