[Solved] Various Session problems

[eluser]fchristant[/eluser]
@N0xie: I am aware of that thread. I still find this part to be interesting:

"But when an AJAX operation is done (get or post), the session is updated and a new session id is generated (and updated in the database) but the cookie in the browser is not updated, so the next time the browser requests a new page it sends a cookie with the wrong session id and the session becomes invalid resulting in loss of session data (person getting kicked out if logged in)."

I do not know why, but in my case an Ajax call does not generate a new session at all. If I access a page, and no session is there yet, it is created. If on that same page Ajax calls are made, those Ajax calls in my setup do not lead to new session entries. What am I missing, perhaps I misunderstand the problem?
