The trick with using the header function call-> NOTHING can be sent to the browser beforehand... that means no <ECHO>, no <PRINT>.. nothing that returns anything to the browser..
ALSO, to ensure that you meet RFC standards (which most web servers support), you want to send the browser a message indicating that you are going to be redirecting the user.
Apache doesn't need this, but FHTTPD does, and its good habit in case you ever change servers.
header("HTTP/1.0 302 Redirection");
header("Location:new_page.php3");
Good luck
