The POST data is sent by the browser, so you can't really alter that... But you can bury an http://php.net/md5 or other random token in the FORM, and put that token in a table in your database, and then on the first POST, you mark that token as "used" On the second POST, a re-load, you can detect that the token was "used" and do whatever you want. Re-direct the user, ignore them completely, give them an error message, blow up their computer. Well, okay, you can do almost whatever you want. -- Like Music? http://l-i-e.com/artists.htm
