HTTP and HTTPS same time

[hajoxx]

I'm successfully listenin port 443 and can access server over https, but I can't access it with http.

var fs = require('fs')
options = {
    ca : fs.readFileSync('./ssl/site.com.pem'),
    key: fs.readFileSync('./ssl/site.com.key'),
    cert: fs.readFileSync('./ssl/site_com.crt')
}

var app = require('express.io')
app.https(options).io()
....
app.listen(443);

I've tried using http and https modules:

app.http().io();
http.createServer(app).listen(80);
https.createServer(options, app).listen(443);

But this time socket.io is giving 404 in browser. How can I solve this? I need to use Express.IO's socket connection because application is based on it.
