package main

import (
	"net/http"
	"net/http/httputil"
	"net/url"

	"github.com/golang/glog"

	"github.com/zenazn/goji"

)

type handle struct {
	host string
	port string
}

func (this *handle) ServeHTTP(w http.ResponseWriter, r *http.Request) {
	remote, err := url.Parse("http://" + this.host + ":" + this.port)
	if err != nil {
		panic(err)
	}
	proxy := httputil.NewSingleHostReverseProxy(remote)
	proxy.ServeHTTP(w, r)
}

func main() {

	defer glog.Flush()

	// proxy
	h := &handle{host: "www.baidu.com", port: "8080"}
	http.Handle("/proxy/", http.StripPrefix("/proxy/", h))

	// Setup static files
	static := web.New()
	publicPath := "static"
	static.Get("/static/*", http.StripPrefix("/static/", http.FileServer(http.Dir(publicPath))))

	http.Handle("/static/", static)

	goji.Serve()
}

/proxy

/static
