#  Send the HEAD request and get the response.

response = http.GetHead("http://www.chilkatsoft.com/")

if (response == nil )

    #  Show the HTTP response code and header received.
    print "HTTP response code: " + "\n";
    print response.get_StatusCode().to_s().to_s() + "\n";

    print "---- FULL HEADER ----" + "\n";
    print response.header() + "\n";
    print "---------------------" + "\n";

    #  How big will the full response be?  This is a good way to
    #  check the size of a download (if the URL is a .zip)
    print "Size of resource = " + response.get_ContentLength().to_s().to_s() + "\n";
