If you are using express.session() you must call your function AFTER express.session() but BEFORE app.router, inside of app.configure().

app.js

app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.session());

  // Give Views/Layouts direct access to session data.
  app.use(function(req, res, next){
    res.locals.session = req.session;
    next();
  });

  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

index.jade

extends layout

block content   
  h1= title   
  p My req.session.var_name is set to #{session.var_name}
