 I'm using cyberduck to test my ftp server and make sure users can resume
 their partial uploads okay.

 I start an upload of a 900 MB file, and let it go to 200 MB and hit stop.

 I do an `ls` on my server and see the partial file is there and it size
 200 MB.

 Then I hit resume in cyberduck and progress bar start going again but it
 doesn't start from 200 MB it start from 100 MB! So all the wrong bytes are
 being appended to my file on the server.

 Does cyberduck have it's own internal integer of what byte to resume from?
 Or does it get the current size from the server for this value?
