Nodejs web server calling requestListener twice when page is loaded

Question

The following is the example web server from the documentation, with an added counter. It prints the counter to the console whenever a client/browser requests the page.

Answer 1

We can ignore the page refresh count due to favicon with the following code snippet:

if (request.url === '/favicon.ico') {
   response.writeHead(200, {'Content-Type': 'image/x-icon'} );
   response.end();
   console.log('favicon requested');
   return;
}
