res.writeHead(200, {"Content-Type": "text/html"});
res.end(content);
});
});
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
console.log('Connection ok!');
io.sockets.on('connection', function (socket) {
socket.emit('message', 'Vous ĂȘtes bien connectĂ© !');
