commit 2b19cf9f9522dd0e8774031a54ce695e73fb72fe
Author: Peter Amstutz <peter.amstutz at curoverse.com>
Date: Wed May 14 14:07:06 2014 -0400
2798: All PUT tests against stub server pass. Added explict setting of
Content-Length to avoid unnecessary chunked transfer encoding, and is also
necessary so slices can directly WriteTo() the socket.
