title: Resumable File Download Protocol
body: <p>I am going to write an application server(RESTFull API) to allow clients to download a zip file, but requirement is the download must be resume-able (due to failure / Network disconnection).</p>
  
  <p>Is there any special protocol made for this??? </p>
  
  <p>If yes please share some contents on this, I am not even able to find anything on google. I am trying to do this in Java(jersey). Thanks </p>
