package main
import (	"log"	"net/http"	"strings")
func main() {	http.HandleFunc("/", rootHandler)	http.HandleFunc("/healthz", healthzHandler)	err := http.ListenAndServe(":8080", nil)	if err != nil {		log.Fatal(err)	}}
func healthzHandler(w http.ResponseWriter, r *http.Request) {	log.Println("/healthz ClientAddress is " + r.RemoteAddr + " Status Code is " + http.StatusText(200))}
func rootHandler(w http.ResponseWriter, r *http.Request) {	for k, v := range r.Header {		w.Header().Add(k, strings.Join(v, " "))	}	log.Println("/ ClientAddress is " + r.RemoteAddr + " Status Code is " + http.StatusText(200))}
