	"github.com/gohttp/response"
)

func main() {
	var buf bytes.Buffer
	client := &http.Client{
		Transport: train.Transport(log.New(&buf, log.Body)),
	}

	ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {
		w.Header().Set("Date", time.Date(2009, time.November, 10, 23, 0, 0, 0, time.UTC).Format(time.RFC1123))
		response.OK(w, "Hello World!")
	}))
	defer ts.Close()

	req, err := http.NewRequest("GET", ts.URL, nil)
	if err != nil {
		panic(err)
	}
	req.Host = "127.0.0.1:54709"
