When needed, I usually loop through the entire $_POST array and concatenate all the values to one (long?) string - then I take an MD5 hash of this string together with the form name and put in the $_SESSION array. Now each time one of my scripts with a form action loads, I include a script in the top which checks the MD5 hash of the current $_REQUEST array with the one in the $_SESSION array using the same name, if it exists - unset($_REQUEST) before the form is normally parsed and action is taken. (This idea of a script came from one of my co-workers) -- Kim Christensen kim.christensen@gmail.com
