    * PROBLEM DESCRIPTION: Need an option to specify the $WSSN     *
    *                      private header without modifying the    *
    *                      Host header.                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    $WSSN is normally set from the original Host header.
    Modifications to the Host header indirectly modify $WSSN, but
    may have other side effects.
    $WSSN is used in the application server similar to the
    standard Host: or non-standard X-Forwarded-Host headers.
    

Problem conclusion

  • If per-request Apache environment variable "ws-override-host"
    is set, the value will be used instead of the Host: header to
    populate $WSSN.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.18 and 9.0.5.6. For more information, see 'Recommended
    Updates for WebSphere Application Server':
