Why does node.js, http-server, show that there are two request coming?

Question

I have the following simple http-server setup using node.js:

var http = require('http');
var port = 12311

http.createServer(function (req, res) {

    console.log("Incomming request from " + req.connection.remoteAddress);

    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end("test string");


}).listen(port);
console.log("Listening on " +  port);

As you can see, when a request comes in, I log it to the console. Now when I browse to localhost:12311 the console shows that two connections have come in:

"E:\Program Files\nodejs\node.exe" hello-world-server.js
Listening on 12311
Incomming request from 127.0.0.1
Incomming request from 127.0.0.1

Why is this?

Answer 1

It's usually the request for the favicon.ico . Even if you don't have one, it's requested as the norm defines a default file path if you don't set the relevant <link rel="shortcut icon"... in the header.

The best ways to find about the requests are :

• client side, by opening the developer tools and looking at the network tab.
• server side, by logging req.url
