Trying to get the session example to work in Express 3.0 alpha

/**

var express = require('express');

var app = express.createServer(
  express.logger()
);
app.use(
    express.cookieParser({ secret: 'keyboard cat' }));
app.use(
    express.session({ secret: 'keyboard cat' }));

app.get('/', function(req, res){
  var body = '';
  if (req.session.hasOwnProperty('views')) {
    ++req.session.views;
  } else {
    req.session.views = 1;
    body += '<p>First time visiting? view this page in several browsers :)</p>';
  }
  res.send(body + '<p>viewed <strong>' + req.session.views + '</strong> times.</p>');
});

app.listen(3000);
console.log('Express app started on port 3000');

This is essentially the same as the session example in the express.js github project. You have to add the cookie and session components, and if you don't add the cookie's secret it complains.

Even after you do that, this happens:

/usr/local/bin/node /Users/dedelhart/OS/test_express_3/app.js
Express app started on port 3000
