Thank you for the info, I have a couple of scripts that I have
occasionally had an issue with being double-submitted, if someone did
a refresh. I was just curious however, instead of redirecting to a
new page, or the same page, if using unset would work as well, after
processing the posted form data, either using unset($_POST); or unset
each assigned key in $_POST individually?
