node.js – 来自远程站点的Socket.io access-control-allow = origin错误

我试图从另一个站点访问socket.io服务器.它工作了几个星期,但现在我不断收到以下错误.从heroku上的服务器访问nodester上的服务器时会发生这种情况.错误是：

XMLhttprequest cAnnot load http://site2.nodester.com/socket.io/xhr-polling//1311008802545. 
Origin http://site1.heroku.com is not allowed by Access-Control-Allow-Origin.
resourcE interpreted as Script but transferred with MIME type text/plain.
Uncaught SyntaxError: Unexpected identifier

这是我如何连接套接字：

socket = new io.socket(
    'site2.nodester.com',{port: 80,rememberTransport: falsE}
);

这是服务器代码：

// requires

server = http.createServer(function(req,res){
    // server stuffs
}),server.listen(8362);

var io = io.listen(server),// io code
