how do sessions work in vb3 beta 7?

[bradsears]

Hi. I'm building an application that uses a bunch of vbulletin functions and tables.

In vb 2.~ I was fine with:

require_once("global.php");
session_start();

Now that I have ported over to vb3b7 I notice that my sessions are gone between pages. I don't understand what they are doing with sessions now, I assume it is for security.

What I want to be able to do is put a variable into a session and be able to access that session on another page.

Does anybody have any ideas as to what I need to understand about vb3b7 and sessions?

Thanks
