Try to write the index.html in this way instead:

 iosocket.on('connect', function () {
      $('#incomingChatMessages').append($('
Connected
'));
 });

 iosocket.on('message', function(message) {
      $('#incomingChatMessages').append($('
').text(message));
 });

 iosocket.on('disconnect', function() {
      $('#incomingChatMessages').append('
Disconnected
');
 });

It may be caused by the other 2 eventlisteners was registered to the connect event. When the client disconnected, the other 2 listeners will still here and doesn't get unregistered.
