【新人】socket.io自动建立很多连接的问题

Question

直接上代码吧,服务器端：

var express=require('express');
var app=express();
var net=require('net');
var http=require('http').createServer(app);
var io=require('socket.io').listen(http);
var net=require('net');
var nodeServer = new net.Socket();
var aSocket=null;

io.sockets.on('connection', function (socketIO) {
  aSocket=socketIO;
};
nodeServer.on('data', function(data) {
 if(aSocket!=null){
    aSocket.emit('pushToWebClient',useData);
    //客户端断开连接
    aSocket.on('disconnect', function () {
      console.log('DISCONNECTED FROM CLIENT');
    });

  }

客户端：

socket.on('pushToWebClient', function (useData) {


    });

代码截取了部分，过程是：从一个C++写的服务器接受数据，socket.io转发数据给客户端，然后显示到页面上。

接受一会，如果关闭网页，就会出现一堆

DISCONNECTED FROM CLIENT
DISCONNECTED FROM CLIENT
DISCONNECTED FROM CLIENT
DISCONNECTED FROM CLIENT
DISCONNECTED FROM CLIENT
DISCONNECTED FROM CLIENT
DISCONNECTED FROM CLIENT
...(此处省略无数行)

我估计是每次io建立了很多次连接，要怎么才能阻止建立这么多呢？
