Riak CS HEAD Object

The HEAD Object operation retrieves metadata from an object without returning the object.

Note: You must have READ access to the object to use this operation.

A HEAD request has the same options as a GET operation on an object, and the HEAD response is identical to the GET response, except that there is no response body.
