Deal and keep node.js/express sessions

I'm currently working on a web app, this web app every time fs.mkdir is called, delete all the current express sessions, so I need a way to keep all this sessions. I was trying to keep all this sessions with connect-mongodb and connect-redis, but neither works, nodemon always says that req.session is undefined. I don't know what I have to do to keep all the session.

I need a way to keep all the sessions, don't lose them when fs.mkdir is executed, and a tutorial for it, because I don't found any good and complete tutorial for this yet, anyone works! I was reading all releated with this here, in Stackoverflow, but anything works! Please help!

it sounds very exotic, that after fs.mkdir your session erased. (I found your other SO question)

But back to the question, here's a little code snippet how you can use sessions (redis).

var express = require('express')
  , fs = require('fs')
  , http = require('http')
  , RedisStore = require('connect-redis')(express)
  , sessionStore = new RedisStore()
  , app = express()
  ;

app.configure(function(){
  app.set('port', 3000);
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser('secret'));
  app.use(express.session({
    store: sessionStore
  }));
  app.use(express.static(__dirname + '/public'));
  app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});

app.get( '/', function(req, res){
  res.setHeader("Content-Type", "text/html");
  console.log( req.session );
  console.log( '------------------------' );
  res.end( 'root' );
});

app.get( '/dir/:id', function(req, res){
  console.log( req.session );
  console.log( '------------------------' );

  fs.mkdir( req.params.id );
  if ( req.session.dirs === undefined )
    req.session.dirs = [];
  req.session.dirs.push( req.params.id );

  console.log( req.session );
  console.log( '------------------------' );

  res.setHeader("Content-Type", "text/html");
  res.end( 'dir' );
});


server = http.createServer(app).listen(3000);

you should read the docs of express, and browse the examples of express
