CI Session problem

[eluser]Akinzekeel[/eluser]
I need the ID because every visitor (=session) must have its own independent cart. Without the session id, visitor A will see whatever visitor B will put in his cart and vice versa.

In the CI guide I did not find any information about my particular problem. And the builtin cart library does require the session library, but there is no technical information on how the cart data is stored. It's probably using the sessions' userdata(), however I need to to several JOINs so as mentioned in my initial post, this is not suitable for me.
