javascript - Node.js: socket.io close client connection -

how can close socket connection on client side?

i using:

• socket.io 0.9
• node.js 0.10.15
• express 3.3.4

i.e.: call localhost/test
-- server side

var test = io .of('/test') .on('connection', function (socket) {    console.log('open socket: ' + socket);    socket.on('disconnect', function () {     console.log('disconnected event');     //socket.manager.onclientdisconnect(socket.id); --> endless loop disconnect event on server side     //socket.disconnect(); --> same here   }); }); 

-- client side

var socket = io.connect('http://localhost:3000/test'); socket.on('disconnect', function () {    console.log('disconnect client event....'); });  socket.emit('getinitdata', function (data) {   .. data }); 

if load test-page need values server (getinitdata).
on first page visit data once, on reload or second visit twice , on.

the connection on server side beeing closed automatically on page reload , if leave page.
on client side connection still open.
how can close connection on client side or check if there open connection?

update
tried following: (client side)

window.onbeforeunload = function(e) {   socket.disconnect(); }; 

this triggers on client side disconnect event, still twice or tripple response.

there no such thing connection on server side and/or browser side. there 1 connection. if 1 of sides closes it, closed (and cannot push data connection closed obviously).

now browser closes connection when leave page (it not depend on library/language/os using on sever-side). @ least true websockets (it might not true long polling because of keep-alive hopefuly socket.io handles correctly).

if problem happens, i'm pretty sure there's bug in own code (on server side). possibly stacking event handlers should not.
