Session Question

Hi All, I have a question about sessions. I need to pass session data from one domain to a secure domain. (www.mydomain.com to www.securedomain.com). I would like to preserve the session data in case the visitor goes back to www.mydomain.com. I thought about just passing the session ID to www.securedomain.com, but if I need to destroy the session while the visitor is in www.securedomain.com, I am hoping this will also include destroying data from www.mydomain.com. Basically, I am talking about a shopping cart system. If the user decides to stop half way through the checkout on the secure site and continue shopping in the store, I want the cart to remain. But if the user completes the checkout process on the secure domain, their cart should be empty when going back to the original domain. Thanks for any help.
