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 dataexport resource exists, or whether the the client has the permission to access it.
