Multiple different shopping cart instances

[eluser]TheManT[/eluser]
I've tried to add products in $cart1 and then show the $cart2.

But when i showed the $cart2, it shows the products i've added in $cart1...

They are getting the values at the session, so don't matter who added the products, all of them will see...

Is there a way to create a new and different session and set it to be used on my cart?
