A path query requires directory marker objects to be present (http://docs.openstack.org/openstack-object-storage/developer/content/ch03s02.html#d5e514)

I would recommend using prefix+delimiter over path. Path query parameters are in swift to support backwards compatibility with the original Cloud Files API.
