    * USERS AFFECTED:  All users of WebSphere eXtreme Scale        *
    *                  who enable HTTP session replication.        *
    ****************************************************************
    * PROBLEM DESCRIPTION: Web application calls for an            *
    *                      HTTP session result in a remote call    *
    *                      to the grid rather than using the       *
    *                      in-memory session object.               *
    ****************************************************************

    *                  because of unnecessary remote calls.        *

    there are multiple web applications configured to use the same
    remote grid, the client might unnecessarily retrieve session
    data from the data grid.
