Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server using Edge Side Include caching      *
    *                  (ESI).                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: A warning occurs if a header is set     *
    *                      on an already committed response.       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Dynacache sets the Surrogate-Control header on the response
    object during ESI processing. If the response is already
    committed a warning is written to SystemOut.log
    

Problem conclusion

  • Dynacache will set the header only if the response is not
    already committed.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.1.0.47, 7.0.0.31, 8.0.0.8, and 8.5.0.1.  Please
