Out of curiosity, why do you store the session ID in the session array when 
session_id() will give you what you are looking for? And then, what does 
session_id() produce? If that is an empty value then $_SESSION['mysession'] 
will be empty as well.

The answers boil down to two things:
1. Check where the session files are written to and make sure that PHP has 
full access to that place and that nothing else wipes those files out.
2. Use this:
<?php
session_start();
header("Cache-control: private");

I use sessions extensively in my projects and didn't find that there is any 
issue. I do set the cache control.
