SESSIONS not staying

[siwelis]

I'm having a problem, where my sessions recognize me being logged in just fine, unless I'm at http://www.url.com/ instead of http://url.com/ ... I want sessions to recognize me as being logged in everywhere on the site, including sub domains... Is this possible?

this may help

 

'session.cookie_domain' should be set to empty string for all local domain names, not only for 'localhost' (but should not be empty for local IP addresses):

 

<?php

ini_set('session.cookie_domain', (strpos($_SERVER['HTTP_HOST'],'.') !== false) ? $_SERVER['HTTP_HOST'] : '');

?>

[siwelis]

session_start();
session_name('SessionMain');

 

That's what I've got so far.

 

I've tried putting that snippet of code above, below, and completely replacing "session_start()"

 

Can someone tell me what I'm doing wrong please if you know? Thank you!
