This is one part correctness and one part potential cost savings if this helps the proxxy servers do the right things.

I haven't tried Content-MD5, to see if S3 uses it for validation, or if it has to be covered by signature.

But I definitely think we should set Cache-Control and Expires along with Content-Length and
Content-Type which we already set. Suggested values:
  Cache-Control: public, no-transform    (public artifact bucket)
  Cache-Control: private, no-transform   (private artifact bucket)
  Expires: <date-time of artifact expiration, ie. when we plan to delete it>
