title: res.flushBuffer() vs res.getOutputStream().flush();
body: <p>What's the difference between calling :  </p>
  
  <pre><code>res.flushBuffer();
  </code></pre>
  
  <p>versus  </p>
  
  <pre><code>res.getOutputStream().flush();  
  </code></pre>
  
  <p>Do these methods flush the same buffer ?  </p>
  
  <p>If so, can you give me a clue on how this buffer is managed by the servlet container?  </p>
