HEAD request

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information contained 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 whether the datacatalog resource exists, or whether the the client has the permission to access it. It can also determine if the aggregatePoints resource supports an output format <format> if performed on a URI with .<format> included.
