        http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
                w.Write([]byte("Hello World\n"))
        })

$ go run main.go

Features

1. Use syscall instead of net or net/http package
2. Asynchronous I/O with epoll

Limitations

• GET only
  • other methods and request body is not available :)
• Headers are not available.
• Although I/O will not be blocked, user-defined handler will be blocked when accessed simultaneously.
