title: Continue an interrupted download on iPhone
body: <p>I use NSURLConnection to download large files from the web on iPhone. I use the "didReceiveData" method to append data to a file in the Documents folder. It works fine.</p>
  
  <p>If the download is interrupted (for instance, because the user pressed the "home" button), I would like to be able to continue to download the next time the user launch my application, and not from scratch!</p>
  
  <p>Anyone can help me ?</p>
