Thanks for your help !

here the code :
Code: Select all#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>

const char* ssid = "         ";
const char* password = "         ";

int LedPin=D3;

ESP8266WebServer server(     );

//Check if header is present and correct
bool is_authentified(){
 
  if (server.hasHeader("Cookie")){   
  String cookie = server.header("Cookie");   
  if (cookie.indexOf("ESPSESSIONID=1") != -1) {
  return true;
  }
  }
  return false; 
  }

//=======================================================
//                handle login

//login page, also called for disconnect
void handleLogin(){
  String msg;
  if (server.hasHeader("Cookie")){

  }
  if (server.hasArg("DISCONNECT")){ 
    String header = "HTTP/1.1 301 OK\r\nSet-Cookie: ESPSESSIONID=0\r\nLocation: /login\r\nCache-Control: no-cache\r\n\r\n";
    server.sendContent(header);
    return;
  }
  if (server.hasArg("USERNAME") && server.hasArg("PASSWORD")){
    if (server.arg("USERNAME") == "123" &&  server.arg("PASSWORD") == "123" ){
      String header = "HTTP/1.1 301 OK\r\nSet-Cookie: ESPSESSIONID=1\r\nLocation: /\r\nCache-Control: no-cache\r\n\r\n";
      server.sendContent(header);
      return;
    }
