func init() {
	http.HandleFunc("/", handler)
}

func handler(w http.ResponseWriter, r *http.Request) {
	c := appengine.NewContext(r)
	transport := &http.Transport{
		Dial: func(network, addr string) (net.Conn, error) {
			c.Infof("connecting socket to %v/%v", network, addr)
			conn, err := socket.Dial(c, network, addr)
			c.Infof("connected socket to %v/%v", network, addr)
			return conn, err
		},
	}
	client := &http.Client{
		Transport: transport,
	}
	resp, err := client.Get("http://www.google.com")
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()
	io.Copy(w, resp.Body)
}
