Understanding Go's net/http package

Go's net/http package deals with HTTP client and server implementations. Here, we are mainly interested in the server implementation. Let us create a small Go program called basicHandler.go that defines the route and a function handler:

package main
import (
    "io"
    "net/http"
    "log"
)
// hello world, the web server
func MyServer(w http.ResponseWriter, req *http.Request) {
    io.WriteString(w, "hello, world!\n")
}
func main() {
    http.HandleFunc("/hello", MyServer)
    log.Fatal(http.ListenAndServe(":8000", nil))
}

This code does the following things: 

1. Create a route called  /hello. 
2. Create a handler called MyServer.
3. Whenever the request comes on the route (/hello), the handler function will be executed.
4. Write hello, world to the response.
5. Start the server...
