(Lianja) HTTP HEAD Request

Sends an HTTP HEAD request and gets the response.

Note: The response to an HTTP HEAD request is always just the response header. The reponse body is always 0 length (thus the reason it's called a "HEAD" request..)

// Otherwise it will be TCP.

    // A failure is when we don't get any response.  It could be a timeout, an inability to connect, etc.
