I am integrating a shopping cart into my site, commerce starter kit, and I have gotten both to read from the same SQL Server with the same application name and I can login on the cart site with the same username and password that I use for my site. My problem is that if I log in to my site, then go to the cart, the cart doesn't recognize me as being logged in. I keep the cart in a sub folder and they both use seperate web.config files. Is there a way to carry it from one place to the other (I don't mean they are on seperate servers by that, they are on the same server). I am new to all of this so I am not even sure where to look to get this to work.

Thank you for your help.
