Apologises about not posting enough of the code, see below for the
methods that sets the respos headers etc
In the method writeResponseHdrs (shown below) we end up reject the
request as bit rate too low and end up executing this code
Log.AdaptVideoError("Video bitrate
["+inputBitRate+"] is
not within range", "Will not encode this video.");
throw new InitialisationException("Video bitrate
["+inputBitRate+"] is not within range. Will not encode this video");
This exception is caught higher up the stack in doPost method which we
then set the status with the following
bufInStream = new
AcceleratorInputStream(request.getInputStream(), 20480);
bufInStream.setHeaderRead();
bufOutStream = new
AcceleratorOutputStream(response.getOutputStream(),20480);
try {
converter = createVideoAdapter(request,
response,
bufInStream,bufOutStream,
request.getContentType(), true,
qualityPolicy);
} catch (Exception ex) {
// caught the exception ok, make sure we have
commited the response
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR );
====== status code set here and sent in do Post
return;
}
So this is the request that I terminate on the client end before the
respone is actually sent by Tomcat, Im not exactly sure were in Tomcat
the code is when I terminate client request. If I terminate at the
correct point then the next request that re-uses that thread is wrong.

*
