In the other scripts I use where I have this problem, I'm using $_POST variables though but still don't get stored in $_SESSION. If I'm correct, this may implies that it is apache that is faulty right?

Okay, let me paraphrase: when I run the ping pong scripts written up there, I have a blank in var_dump($_SESSION) if and only if I have 

[Mon Mar 18 13:25:37 2013] [error] [client 184.151.114.111] PHP Notice:  Undefined index: push in /home/www/www.ngenioconnect.com/Modules/MPOSurveyTest/pong.php on line 8

on apache log. So my question really is, it is apache that handles the posts and gets requests, as I use both and it seems that the non-persistence of data occurs before the storage in $_SESSION, is it possible that it is Apache that is faulty?
