Magento Hosting : multiple domain multiple store single checkout

Magento is the leading e-commerce platform rapidly gaining in popularity. Start your own online store powered by magento now by hosting your store either with our recommended webhost or with the providers of the best dedicated servers This magento discussion was started by Pierceaxiom on 03 july 2009 I have set up the multiple store on multiple domain but I am having some issues with the checkout. When using the store switcher it adds the SID in the url which is bad but I am willing to deal with that for now until everything is up and running correctly. When it adds the SID it shares the cart fine but for some reason it does not always pass the SID. My setup is i have three stores inside of one mall. It is setup exactly like the magento multistore demo . The main mall that holds all products and three other individual stores. So the domain setup would be mall.com with the three stores store1.com, store2.com, and store3.com One thing i did notice when i turned off the passing of the SID in the url the cart did not share between stores. But if i login to store1.com and put something in my cart and switch to store2.com then nothing is in the cart. When i login under my account to store2.com suddenly the cart has the item from store1.com in the cart. So in order for it to work across all the stores I would have to login to each store separately then it would share the cart. But that is annoying especially for a customer. So there are two problems if one is solved then i don’t have to worry about the other: 1) I was thinking maybe there is a way to login to one store and have it login in to all stores 2) A way to fix the passing of the SID to pass the SID everytime the domain name is changed…which to my understanding is the way it is suppose to work but it doesn’t Learn more about magento here .
