* Takes as input the HttpContext instance for the current request and the SessionID value for the current request.
* Retrieves session values and information from the session data store and locks the session-item data at the data
* store for the duration of the request. The GetItemExclusive method sets several output-parameter values that inform
* the calling SessionStateModule about the state of the current session-state item in the data store.
*
* If no session item data is found at the data store, the GetItemExclusive method sets the locked output parameter to
* false and returns null. This causes SessionStateModule to call the CreateNewStoreData method to create a new
* SessionStateStoreData object for the request.
*
* If session-item data is found at the data store but the data is locked, the GetItemExclusive method sets the locked
* output parameter to true, sets the lockAge output parameter to the current date and time minus the date and time when
* the item was locked, sets the lockId output parameter to the lock identifier retrieved from the data store, and returns
* null. This causes SessionStateModule to call the GetItemExclusive method again after a half-second interval, to attempt
* to retrieve the session-item information and obtain a lock on the data. If the value that the lockAge output parameter
* is set to exceeds the ExecutionTimeout value, SessionStateModule calls the ReleaseItemExclusive method to clear the lock
* on the session-item data and then call the GetItemExclusive method again.
*
* The actionFlags parameter is used with sessions whose Cookieless property is true, when the regenerateExpiredSessionId
* attribute is set to true. An actionFlags value set to InitializeItem (1) indicates that the entry in the session data
* store is a new session that requires initialization. Uninitialized entries in the session data store are created by a
* call to the CreateUninitializedItem method. If the item from the session data store is already initialized, the
* actionFlags parameter is set to zero.
*
* If your provider supports cookieless sessions, set the actionFlags output parameter to the value returned from the session
* data store for the current item. If the actionFlags parameter value for the requested session-store item equals the
