> When an offset is specified, the HTTP header Content Length still contains the original file size. e.g. if the original file is 100 bytes, and the offset specified it 10, then HTTP Content Length ought to be 90. Currently it is still returned as 100.
> This causes curl to give error 18, and JAVA to throw ConnectionClosedException
