gistfile1.js

var requirejs = require('requirejs');

requirejs.config({
    nodeRequire: require
});

requirejs(['express', 'connect', 'connect-redis'], function(express, connect, ConnectRedis) {

  var app = express.createServer();
  var RedisStore = new ConnectRedis(express);

  var sessionStore = new RedisStore();

  // Configuration
  app.configure(function(){
    app.set('views', __dirname + '/views');
    app.set('view engine', 'jade');
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.static(__dirname + '/public'));
    app.use(express.cookieParser({maxAge: app.settings.cookieMaxAge}));
    app.use(express.session({ store: sessionStore , secret: "your mother wears army boots", key: 'express.sid'}));
    app.use(app.router);
  });

  // Setup Routes
  app.get('/', function(req, res){
    if(req.query.add != undefined)
      req.session.counter = (req.session.counter)? req.session.counter + 1 : 0;
    res.render('index', {'title': "testing redis session counter", 'counter' : req.session.counter});
  });

  var port = process.env.PORT || 3002;
  app.listen(port);
  console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);
