The System.Web.SessionState.SessionStateModule object calls the SessionStateStoreProviderBase.CreateNewStoreData(System.Web.HttpContext, int) method at the beginning of a request for an ASP.NET page, during the System.Web.HttpApplication.AcquireRequestState event. The SessionStateStoreProviderBase.CreateNewStoreData(System.Web.HttpContext, int) method is called if:

• the incoming request has no session ID, or

• the incoming request has a session ID, but the session is not found in the data store.

The SessionStateStoreProviderBase.CreateNewStoreData(System.Web.HttpContext, int) method creates a new System.Web.SessionState.SessionStateStoreData object with an empty System.Web.SessionState.ISessionStateItemCollection object, an System.Web.HttpStaticObjectsCollection collection, and the specified timeout value. The System.Web.HttpStaticObjectsCollection collection for the ASP.NET application can be retrieved using the SessionStateUtility.GetSessionStaticObjects(System.Web.HttpContext) method.
