A Simple Tunnel let TCP connection looks like HTTP request. Server side also with a simple web/file server. For the normal browser, the server side is just a website. Suggest using long connection(Multiplexing/VPN) with this tool.

• 3 http requset for initial
  • ws mode: 2 http requset
• 2 tcp connection for data transmission
  • ws mode: 1 tcp connection

Client: ./httptun-client -t "HTTPTUN_SERVER_IP:4040" -p ":5005"
Server: ./httptun-server -t "TARGET_IP:5005" -p ":4040"

The above commands will establish port forwarding for 8388/tcp as:

Application -> httptun Client(5005/tcp) -> httptun Server(4040/http) -> Target Server(5005/tcp)

Tunnels the original connection:

Application -> Target Server(5005/tcp)

server side:

	// simple http Handler setup
	fileHandler := http.FileServer(http.Dir(*dir))
	//http.Handle("/", fileHandler) // do not add to http.DefaultServeMux now
	http.HandleFunc("/hello", func(w http.ResponseWriter, r *http.Request) { // other Handler
		io.WriteString(w, "Hello, world!\n")
	})

	websrv := fakehttp.NewHandle(fileHandler) // bind handler
	websrv.UseWs = true
	websrv.OnlyWs = false
	http.Handle("/", websrv) // now add to http.DefaultServeMux

	// start http server
	http.ListenAndServe(":8080", nil)
