Error: The connection to  was interrupted while the page was loading.

I am new to socket.io and I have tried to search for this, but I didn't get an answer.

Websocket is interrupted when I refresh page on Firefox. That's why server side is waiting to authorise client.

Here is code: server.js

var app = require('http').createServer(handler),
  io = require('socket.io').listen(app),
  fs = require('fs')

app.listen(8080);

function handler(req, res) {
  fs.readFile(__dirname + '/index.html',
    function (err, data) {
      if (err) {
        res.writeHead(500);
        return res.end('Error loading index.html');
      }
      res.writeHead(200);
      res.end(data);
    });
}

io.sockets.on('connection', function (socket) {
  socket.emit('news', {
    hello: 'world'
  });
  socket.on('my other event', function (data) {
    //alert(JSON.stringify(data));  
    console.log(data);
  });

});
