Sticky-Session not working in IE and FireFox

[doanmanhsonha]

Hi everyone,
I write a simple code to try sticky-session and socket-io.
With Google Chrome, I can see "Hello World!" return.
IE and FF keep loading and nothing return.
Can you give me hint how to settle my problem?
Here is the source:
var sticky = require('sticky-session');
var fs = require('fs');
sticky(function () {
// This code will be executed only in slave workers

var http = require('http'),
    io = require('socket.io');

var server = http.createServer(function (req, res) {
    if (req.url === '/' || req.url === '/index.html') { 
        fs.readFile(__dirname + '/statics/html/index.html',
        function (err, data) {
            if (err) {
                res.writeHead(500);
                return res.end('Error loading index.html');
            }

            res.writeHead(200, {'Content-Type': 'text/html'});
            res.end(data);
        });
    }
});
io.listen(server);

return server;

}).listen(8000, function () {
console.log('server started on 8000 port');
});

I had the same problem even sometimes with Chrome and Safari!!!
I think the problem is somewhere in the ip hash.

Same problem here. Any news on this issue? How do you make it work on FF, IE?

This problem always occurs on my IE.
Sometimes it works correctly on my Firefox, and Chrome.
