Right I see what you mean, I was thinking about what you said, could I do this:
User comes to a.com for the first time so has no identifier. User then clicks add to basket button, the code calls the AddProductToBasket webservice method which takes the parameters ProductID and Identifier, the identifier is pulled from the
cookie on a.com but in this instance the cookis is empty so the method is called as follows :
checkout.com's AddProductToBasket method checks to see if the Identifier passed is nothing, if so it creates one and can now create a basket. The method returns the identifier to
a.com and then it can set it in its own cookie. So the next time the user wants to add a product or view the basket contents it can pass the identifier stored in the cookie in its domain. The user doesn't need to sign on until they want to
I think this works on similar lines as you have said above, can you see any potential problems?
