2.1.5 ASP.NET
ASP.NET primarily relies on existing industry standard web protocols for data communication. Microsoft has implemented two protocols that are specific to ASP.NET for administrative communications with servers hosting ASP.NET web applications.
The ASP.NET State Server Protocol ([MS-ASP]) specifies an out-of-process state server that is responsible for storing session state used by client applications that require persistent session state storage. [MS-ASP] uses HTTP as its transport.
The ASP.NET State Service Database Repository Communications Protocol ([MS-ASPSS]) specifies an interface for clients to store and retrieve serialized session data.
