DOC: Statement in the Session-State Store Topic in the .NET Framework SDK Documentation May Be Misleading

In the Microsoft .NET Framework Software Development Kit (SDK) documentation (versions 1.0 and 1.1), the "Session-State Store" topic (under "Session State") contains some information that may be misleading.

On a computer that has the .NET Framework SDK documentation installed, see the "Session State" page at the following location:

In the .NET Framework SDK version 1.0
ms-help://MS.NETFrameworkSDK/cpguidenf/html/cpconsessionstate.htm (ms-help://MS.NETFrameworkSDK/cpguidenf/html/cpconsessionstate.htm)
In the .NET Framework SDK version 1.1
ms-help://MS.NETFrameworkSDKv1.1/cpguidenf/html/cpconsessionstate.htm (ms-help://MS.NETFrameworkSDKv1.1/cpguidenf/html/cpconsessionstate.htm)

MORE INFORMATION

The following statement in the .NET Framework SDK documentation may cause you to believe that only SqlServer session mode supports failover cluster Web servers:
In SQL mode, session state can also be configured to work in a failover cluster. A failover cluster is two or more identical, redundant Web servers that store their session data on a separate computer in a SQL Server database.
However, both SqlServer session mode and StateServer session mode support failover cluster Web servers and Web farms.
The following statement in the .NET Framework SDK documentation may cause you to believe that StateServer session mode supports only Web farms:
Partitioning an application across multiple Web farm computers
Because all state is stored separately from worker processes, you can partition an application across multiple worker processes running on multiple computers. The model for communicating state between a worker process and a state service running on different computers is almost the same as that for processes and servers running on the same computer. In either case there can only be one State Server per Web farm.
However, SqlServer session mode also supports failover cluster SQL Server (this is different from failover cluster Web server).
