Sometimes in my code I use the Header('Location: index.php?var=value');

by PHP, the rest of the script gets executed.
I'm thinking that this is the problem because I've eliminated all the
occurrences where the SESSION var was cleared until only one exists and
it was after a Location Header.
I've put an exit(); after the header and the problem was gone... :)
Is this the correct PHP/HTML behavior or is there another problem? Am I
supposed to put an exit(); after a header "Location" to make sure that
no more code gets executed?
Redirecting using a Location header is not the only thing you can do
with the header() function. It will never end processing of the script
no matter what you pass to it. The example on the manual page for the
header() function says as much (http://php.net/header), you read that right?
<?php
header("Location: http://www.example.com/";); /* Redirect browser */
/* Make sure that code below does not get executed when we redirect. */
exit;
?>
