In the following hypothetical architecture, with Servlets sitting on the App Servers machines ( pool of app servers residing on different physical machines), is there any issues using Session objects to store client information?
 
If client A is being served from the ServletA of AppServerA which stored the shopping cart for client A and then in the next request, client A is being served from the ServletA of AppServerB, would the ServletA residing on AppServerB be able to retrieve the correct session objects?
