===============================================================================
    SPEC has discovered a code defect in the SPECweb99_SSL test harness run on 
    the client systems used in this result.  The bug prevents these client systems
    from generating the correct SPECweb99_SSL workload.  Specifically, the bug
    in the SPECweb99_SSL code results in the clients not generating any of the
    required SSL ClientKeyExchanges during the benchmark.  Therefore, the
    results presented here are not comparable with any other SPECweb99_SSL
    results.
