The System.Web.Configuration.SessionStateSection class refers to the element in the Machine.config or Web.config configuration file identified by the sessionState tag.
When a new client begins interacting with a Web application, a session ID is issued and associated with all the subsequent requests from the same client during the time that the session is valid. This ID is used to maintain server-side state associated with the client session across requests. The System.Web.Configuration.SessionStateSection controls how the ASP.NET application establishes and maintains this association on behalf of each client.
This mechanism is very flexible and gives you the ability to host session-state information out of process and to track state without using cookies, among other things.
