Function hello

examples/http-server/http-server.go:15–23

A fundamental concept in `net/http` servers is *handlers*. A handler is an object implementing the `http.Handler` interface. A common way to write a handler is by using the `http.HandlerFunc` adapter on functions with the appropriate signature.

(w http.ResponseWriter, req *http.Request)

// a handler is by using the `http.HandlerFunc` adapter
// on functions with the appropriate signature.
func hello(w http.ResponseWriter, req *http.Request) {

	// Functions serving as handlers take a
	// `http.ResponseWriter` and a `http.Request` as
	// arguments. The response writer is used to fill in the
	// HTTP response. Here our simple response is just
	// "hello\n".
	fmt.Fprintf(w, "hello\n")
}

func headers(w http.ResponseWriter, req *http.Request) {
