I am unable to figure out why disconnecting / connecting a socket.io connection multiple times is not working ?

Server side code:

io.on(\'connection\', f

    Have you tried this config in client ?

    // 0.9  socket.io version
io.connect(SERVER_IP, {'force new connection': true});

// 1.0 socket.io version
io.connect(SERVER_IP, {'forceNew': true});

    This solution, based on Jujuleder's answer works. Apparently in socket.io 1.0, it is "forceNew" instead of "force new connection" - both work though.

    Server:

    var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res){
    res.sendfile('s.html');
});

io.on('connection', function(socket){
    console.log('a user connected: ' + socket.id);
    socket.on('disconnect', function(){
        console.log( socket.name + ' has disconnected from the chat.' + socket.id);
    });
    socket.on('join', function (name) {
        socket.name = name;
        console.log(socket.name + ' joined the chat.');
    });
});

http.listen(3000, function(){
    console.log('listening on *:3000');
});

    Client (s.html):

    <!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
    <style>button{width: 100px;}input{width: 300px;}</style>
</head>
<body>

<ul id="messages"></ul>

<button id="disconnect">disconnect</button>
<button id="connect">connect</button>

<script src="/socket.io/socket.io.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>

    var socket = io.connect('http://localhost:3000');

    $('#disconnect').click(function(){
        socket.disconnect();
    });
    $('#connect').click(function(){
//        socket.socket.reconnect();
//        socket = io.connect('http://localhost:3000',{'force new connection':true });
        socket = io.connect('http://localhost:3000',{'forceNew':true });
        socket.on('connect', function(msg){
            socket.emit('join', prompt('your name?'));
        });
    });
    socket.on('connect', function(msg){
        socket.emit('join', prompt('your name?'));
    });
    socket.on("disconnect", function(){
        console.log("client disconnected from server");
    });

</script>
</body>
</html>
