title: WebSphere response buffering
body: <p>I'm writing a large response (hundreds of Mb) to the WebSphere's response.getOutputStream().
  It appears that Web Sphere always store whole output stream data in some internal in-memory buffers before serving it to the cient. So my servet processing (generating data) finishes in seconds while browser may still be downloading it for half an hour. During that time whole response remains buffered in memory.</p>
  
  <p>Is it possible to avoid this buffering?
  I'd prefere more servlet threads waiting for the output stream than wasting Gbs of memory.</p>
  
  <p>My Web Sphere version is 8.5.0.</p>
  
  <p>I've tried setting content length and chunked response - it's all the same, still buffering.
  My TCP transport chain settings are default with 32 kb response buffer, but it is ignored somehow.</p>
