Session question

[trigger8]

<?php
session_start();
if (isset($HTTP_SESSION_VARS["Username"])) {
if (true || !(isset($HTTP_SESSION_VARS["UserAuthorization"])) || $HTTP_SESSION_VARS["UserAuthorization"]=="" || strpos($authorizedUsers, $HTTP_SESSION_VARS["UserAuthorization"])) {
$grantAccess = 1;
}
}
?>

Do I need to put "exit;" in the above statement?

Nope.
