Calls initialization code when a System.Web.SessionState.SessionStateModule object is created.
This method is not intended to be called from application code.
An System.Web.HttpApplication is created when an ASP.NET application is started. The System.Web.HttpApplication object calls the SessionStateModule.Init(System.Web.HttpApplication) method when it creates the System.Web.SessionState.SessionStateModule object for the application. The System.Web.SessionState.SessionStateModule class is specified in the configuration for an application.
