title: response.flushBuffer() is not working
body: <p>I am trying to implement a servlet for streaming large objects: </p>
  
  <pre><code>    oracle.sql.BLOB blob = rs.getBLOB('obj');
      InputStream in = blob.getBinaryStream();
  
      int bufferSize = 1024;
      byte[] buffer = new byte[bufferSize];
  
      ServletOutputStream out = response.getOutputStream();
  
      int counter=0
      while((length=in.read(buffer)) != -1){
          out.write(buffer,0,length);
          counter++;
          if(counter % 10 == 0){
          counter=0;
          response.flushBuffer();
      }
  </code></pre>
  
  <p>This code suppose to send data to client chunk by chunck. Now what's happening is that when I stream large object (100 MB), memory goes up, and server dies sometimes if there are more than one parallel downloads/stream.</p>
  
  <p>Why this <code>flushBuffer()</code> is not sending data to client? The client get popup for open/save file only after response closes.</p>
