New Post: Add Item into Cart by SQL Insert

Hi there,

I use the Methode

AddItemToCart

and it works fine, the Methode add the Product to the cart. My User is logged on, but when I Redirect to Cart all Items will be deleted in the table.
Cookies are accepted by the browser. Do I have to call the Cart by the Cart ID or do I have something others to keep my Cart Items still alive ?
Is it necessary to add the user reference to the current cart?

There are tree different ways to add Items to the cart.
I use the method without the UserInfo, because all others does not match my rerquirements.

Thanks in Advance
