Connect sessions only on certain routes

gistfile1.js

var session = express.session();

// Slightly Invasive
app.get('/home', session, routes.home);
app.get('/about', routes.about);
app.get('/faq', routes.faq);

// or

// Crude
var excludedPaths = ['/about', '/faq'];
app.use(function (req, res, next) {
  if (excludedPaths.indexOf(req.url) >= 0) return next();
  session(req, res, next);
});
