Problem summary
****************************************************************
* USERS AFFECTED: All WebSphere Application Server users       *
****************************************************************
* PROBLEM DESCRIPTION: The webserver plugin flushes the        *
*                      output after sending the request to     *
*                      the appserver.  This sometimes causes   *
*                      part of the response to be lost.        *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The plugin flushes both the input and output buffer when
sending the response to the appserver.  This normally is
fine except in the case when a 100 Continue requests are sent
and the servlet does not wait for the POST content before
sending the response.  Flushing of the buffer in this case
would result in the loss of the response headers.
Problem conclusion
The plugin was modified to only flush the output buffer
when sending the request to the appserver.
