Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server web        *
*                  server plugin users                         *
****************************************************************
* PROBLEM DESCRIPTION: A 400 error response can be logged      *
*                      when plugin ESI caching is enabled      *
*                      and the client terminates during        *
*                      response processing.                    *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When plugin ESI caching is enabled and the response does
not caching, if the client disconnects a 400 response code
will be reported in the web server access.log

Problem conclusion

Code has been corrected to indicate the actual response code
when the client disconnects under these conditions.

The fix for this APAR is currently targeted for inclusion in
