	defer conn.Close()

	credentials := client.LongtermCredentials("username", "password")
	dialer, err := client.NewDialer(&credentials, conn)
	if err != nil {
		log.Fatal("failed to obtain dialer: ", err)
	}

	httpClient := &http.Client{Transport: &http.Transport{Dial: dialer.Dial}}
	httpResp, err := httpClient.Get("http://www.google.com/")
	if err != nil {
		log.Fatal("error performing http request: ", err)
