Problem summary

• ****************************************************************
  * 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.               *
  ****************************************************************
  * RECOMMENDATION:  The web application performance suffers     *
  *                  because of unnecessary remote calls.        *
  ****************************************************************
  When you use eXtreme Scale for HTTP session replication, and
  there are multiple web applications configured to use the same
  remote grid, the client might unnecessarily retrieve session
  data from the data grid.
  

Problem conclusion

• This fix eliminates unnecessary remote calls in a multiple web
  application environment.
