(Go) 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..)

Note: This example requires Chilkat v11.0.0 or greater.

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    http := Http_Ref.html">chilkat.NewHttp()

    // If the URL uses "https://", then the connection will be TLS.
    // 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.
    // For example, a "404 Not Found" response is still a response, and thus deemed success in terms of the API..
