// response.sendDate() APi 
    
// Importing http module  
var http = require('http');  
    
// Setting up PORT  
const PORT = process.env.PORT || 3000;  
    
// Creating http Server  
var httpServer = http.createServer( 
  function(request, response){  
  
  // Checking if date header has been 
  // sent or not by using sendDate API 
  const value = response.sendDate; 
    
  // Display result 
  // by using end() api 
  response.end( "Date header status:" 
    + value, 'utf8', () => {  
      console.log("displaying the result...");  
  
      // Closing the server 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  });

      // Closing the server 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  }); 
};  
    
// Creating http Server and listening 
// on the port 3000 
var httpServer = http.createServer( 
    http2Handlers).listen(3000, () => {  
    console.log("Server is running at port 3000...");
