Protecting Pages Code? What am I doing wrong. Please help

Hi there,

I am having an issue protecting sub-folders within sub-folders with PHP.

I have been protecting pages with only short directories (doing fine), but now I am wanting to protect new directories with a number of sub-directories and that is where I am having troubles.


Example:
PHP Login Script Location: http://www.mydomain.com/login/free/main.php


Works Fine -
Pages Protected: http://www.mydomain.com/login/free/members/free.php

Does not work -
Wanting Pages Protected: http://www.mydomain.com/login/free/members/free/archive/directory/2008.php
(and branched out from there)


This is the code I use on tops of all my pages, but the long one's do not work...

Code:

---

<?php
include("..../include/session.php");
if(!$session->logged_in){ header("Location: ..../main.php"); } else {
?>
<!-- -->

---

Only "../" works, not "..../" or "....../".

Can anyone tell me why this is the case and what I am doing wrong.

Thanks
