Created a small hello world app that emit hello world every 2s, but when I kill my node.js server the socket.io clients continue to pool, except IE9 I try to use socket.disconnect but that does not appear to work. Am i misusing this?
var app = require('http').createServer(handler)
var io = require('socket.io')(app);
var fs = require('fs');
app.listen(8080);
function handler (req, res) {
fs.readFile(__dirname + '/client.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading client.html');
}
res.writeHead(200);
res.end(data);
});
}
io.on('connection', function (socket) {
socket.emit('news', { msg: 'hello world!' });
setInterval(function(){
socket.emit('news', { msg: 'hello world!' });
},2000);
socket.on('my other event', function (data) {
console.log(data);
});
});Server.js

Do I have to handle this on my side or does socket.io handle this for me?
