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
