Session-Level Data and Scalability Information

MORE INFORMATION

A. You can install Commerce Server on multiple computers running Internet Information Server (IIS) and use round-robin DNS to scale to your needs. Because it is not possible to maintain Session-level data across multiple servers, Microsoft does not recommend using Commerce Server components at the Session-level. However, in a single computer installation, you may be able to use Session-level data. In this case, it is recommended that you test the system thoroughly. The starter stores (Clockped, Volcano Coffee, Adventure Works, MS Press) that come with Commerce Server do not use any Session-level data.
