This is useful for retrieving meta-information written in response headers, without having to transport the entire content. The meta-information includes the media-type, content-encoding, transfer-encoding, content-length, etc.

HEAD request can be used to check if the clusterMemberLoad resource exists, or if the clusterMemberLoad resource can be accessed by clients. It can also determine if the clusterMemberLoad resource supports an output format <format> if performed on a URI with .<format> included.
