Hi,

Am using "net/http/httputil" Reverse proxy and would to make HTTPS forwarding between the two proxy servers. Any help on how to handle HTTPS between the proxy servers instead of HTTP?

Here are a sample of my code.

Proxy A

func main() {

http.HandleFunc("/", proxyPassA)
server.ListenAndServeTLS(certFile, keyFile)
}

func proxyPassA(res http.ResponseWriter, req *http.Request) {

server := NewServer("127.0.0.1:8080")

ServerB := http://127.0.0.1:10010

url, _ := url.Parse(ServerB)
proxy := httputil.NewSingleHostReverseProxy(url)
proxy.ServeHTTP(res, req)
}

// NewServer - Create a new server
func NewServer(addr string) *http.Server {

   return &http.Server{
        Addr: addr,
        TLSConfig:    tLSConfig(),
        ReadTimeout: 5 * time.Second,
        WriteTimeout: 10 * time.Second,
        IdleTimeout: 120 * time.Second,
   }
}

Proxy B

func main() {

http.HandleFunc("/", proxyPassB)
server.ListenAndServeTLS(certFile, keyFile)
}

func proxyPassA(res http.ResponseWriter, req *http.Request) {

server := NewServer("127.0.0.1:7070")

remotehttpserver := http://127.0.0.1:6001

url, _ := url.Parse(remotehttpserver)
proxy := httputil.NewSingleHostReverseProxy(url)
proxy.ServeHTTP(res, req)
}

// NewServer - Create a new server
func NewServer(addr string) *http.Server {

   return &http.Server{
        Addr: addr,
        TLSConfig:    tLSConfig(),
        ReadTimeout: 5 * time.Second,
        WriteTimeout: 10 * time.Second,
        IdleTimeout: 120 * time.Second,
   }
}
