title: Difference between connect-flash in node.js and console.log?
body: <p>From what I understand, both do server printouts. I tried using flash below and I only see the console printout.</p>
  
  <pre><code>app.get('/', function(req, res){
      console.log('hi there!');
      req.flash('info', 'flash test');
      req.end();
  });
  </code></pre>
  
  <p>What's flash used for and how should I be using it?</p>
