I want to share a session id used to identify users shopping carts  
across multiple domains…www.domain1.com, [www.domain2.com](http://www.domain2.com)  
[wwww.domain3.com](http://wwww.domain3.com).

I am going to have all the data about the order stored in a database,  
and pull the information with a session id.

All three sites will be sharing the same DB, but I need a way to share  
the session ID across all the domains. Anyone have any suggestions?
