Another little nift thing ive learned to always do regarding headers,
is to always - ALWAYS - after a location have an exit;

Example :

header("location: somewhere.php");

Ive learned that sometimes someting odd happens to the server and
PHP delivers notices and errors to the browser. Sometimes something
in your code could go wrong leading to a header not working the way
intended. Point is, having the exit atleast stops the user from getting
alot of stuff which he didnt accually want on the screen.

I remember one of my earlier login systems, and if the login wasnt valid
the user was sendt to the login page, pretty old fashioned. Problem was
I didnt have an exit behind, and the webserver got a hickup. There happened
someting wrong with the /tmp folder on the server so PHP issued an error
on all pages that there was errors with the sessions, meaning something was
printed out before my validation of the login, and the user accually got the
content he wasnt allowed to see, :)

This is abit off topic, but you never know. Headers are headers, and
small things are small things...

Good luck.
