The current System.Web.HttpContext object that references server objects used to process HTTP requests (for example, the System.Web.HttpContext.Request and System.Web.HttpContext.Response properties).
The System.Web.SessionState.SessionStateModule calls the SessionIDManager.RemoveSessionID(System.Web.HttpContext) method during the System.Web.HttpApplication.ReleaseRequestState event to remove the session identifier from the System.Web.HttpResponse.Cookies collection if a new session was created but was not used.
