title: Apache Camel download progress
body: <p>I am using Apache Camel to download FTP files.</p>
  
  <p>Is there a way to get the download progress?  The headers expose the total file size, but I don't have any access to the download byte stream, as far as I can find.  If I did, I could manually tally up the bytes, and divide that by the total to get a percentage.  </p>
