    public class HttpHead

extends HttpRequestBase

HTTP HEAD method.

The HTTP HEAD method is defined in section 9.4 of RFC2616:

> The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response. The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request. This method can be used for obtaining metainformation about the entity implied by the request without transferring the entity-body itself. This method is often used for testing hypertext links for validity, accessibility, and recent modification.

  4.0
