Reply Header Name           Value

* All metadata replies, at all levels, include latest modification information.

* At all levels, a ``GET`` request may use ``If-Modified-Since`` and ``If-Unmodified-Since`` headers.

* Container/object lists include all associated metadata if the reply is of type json/xml. Some names are kept to their OOS API equivalents for compatibility. 

* Multi-range object GET support as outlined in RFC2616.

* Object hashmap retrieval through GET and the ``format`` parameter.

* Partial object updates through POST, using the ``Content-Length``, ``Content-Type``, ``Content-Range`` and ``Transfer-Encoding`` headers.

* Object ``MOVE`` support.

* Time-variant account/container listings via the ``until`` parameter.

* Large object support with ``X-Object-Manifest``.
