sessions in cscart

I have quick question about sessions in cscart.

What i want to do is … i want to write some short php scripts inside cscart, so user can login to that script,update their product, and logout. (i know cscart has “manage product” feature in the admin, i have my reason to do this approach).

So the script will be inside the subfolder of the cscart.

My question is, in my script, when user login, i need to initialize a session, but i also don’t want to conflict with the existing cscart session. What will be the best approach?

Please help
