Socket.io跨域

Question

使用NodeJS-Socket.io构建我的应用时遇到跨域问题。

这是我的服务器：

console.log("Starting server...")
var express = require('express'),
app = express(),
server = require('http').Server(app),
io = require('socket.io')(server),
compress = require('compression')(),
sqlite3 = require('sqlite3');

app.use(compress);
app.disable('x-powered-by');

app.use(function (req, res, next) {
        console.log('Setting configuration');
        res.setHeader('Access-Control-Allow-Origin', "http://fo-member.dev.game.com");
        res.setHeader('Access-Control-Allow-Origin', true);
        res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
        res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
        next();
    }
);

server.listen(11081);
io.set("origins","http://fo-member.dev.game.com");
console.log("Server started listening on 11081");

它在端口11081上运行。我已将apache配置为从端口80转发到节点服务器，如：

NameVirtualHost fo-node.dev.game.com:80
<VirtualHost fo-node.dev.game.com:80>
ServerName fo-node.dev.game.com
ServerAdmin contact@game.com

ErrorLog "logs\game-fo-node.error.log"
CustomLog "logs\game-fo-node.access.log" common
ProxyRequests Off
ProxyPreserveHost On 

<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>

<Location />
    ProxyPass http://localhost:11081/
    ProxyPassReverse http://localhost:11081/
</Location>

</VirtualHost>

我有一个在11080（它是tomcat）上运行的前端服务器，并且还是域上的apache的forware端口：http://fo-member.dev.game.com

在前端，我可以通过以下方式获取socket.io/socket.js：

<script type="text/javascript" src="http://fo-node.dev.game.com/socket.io/socket.io.js"></script>

现在看起来很好。但是当我从前端执行连接操作时，例如：

var socket = io.connect('http://fo-node.dev.game.com/notify');

            socket.on("connect", function() {
                console.log("connected");
                // Let the server know who is connected...
                socket.emit("user", { Id: 101 });
            });
            socket.on('update', function (data) {
                // Do something cool like update badges/status/etc...
                console.log(data);
            });

客户端控制台显示错误：

XMLHttpRequest cannot load http://fo-node.dev.game.com/socket.io/?EIO=2&transport=polling&t=1401700586028-90. Credentials flag is 'true', but the 'Access-Control-Allow-Credentials' header is ''. It must be 'true' to allow credentials. 

此外，我已经在apache中添加了头配置允许跨域：

<IfModule mod_headers.c>
SetEnvIf Origin "http(s)?://(www.)?(fo-member.dev.game.com|fo-rest.dev.game.com|fo-node.dev.game.com)$" AccessControlAllowOrigin=$0$1
   Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
</IfModule>

这是请求标题：

我感谢你的阅读，也许你们可以让我知道我的错误。
