title: Save chunks of http.request into grifFS node.js
body: <p>You can save the data received from a <code>http.request</code> post directly into GridFS to minimize memory usage? Can anyone give me an example,
  Note: the size of data are 10Mb+, im using Post to send and i can't do this</p>
  
  <pre><code>request.addListener('data', function (chunk) {
      data += chunk;
  });
  </code></pre>
  
  <p>because I need to minimize memory usage.
  I need something like: </p>
  
  <pre><code>request.addListener('data', function (chunk) {
     db.append(chunk);
  });
  </code></pre>
