title: Node.js Download Manager
body: <p>I have to build a download manager for big files (over 500MB) for Mac, PC and Linux.
  I am going to use <a href="http://appjs.com" rel="nofollow">App.js</a> to make the client program.
  The idea for this manager is to keep the current download progress if the connection drops.  </p>
  
  <p>My question is how to make save the current download state/% and continue when the connection is OK.</p>
