title: Route client to external site in node.js?
body: <p>This may be stupadly easy, or just impossible - but it's worth asking in my opinion.</p>
  
  <p>The reason is because I was trying to demo a quick and dirty (lol) url-shortening app.</p>
  
  <pre><code>app.get('/link/:key', function(req, res){
    client.get(req.params.key, function(err, reply){
      if(client.get(reply)){
        // route to reply here
      }
      else{
        res.render('index', {
          link: null
        });
      }
    });
  });
  </code></pre>
  
  <p>How would I perform that route, if possible?</p>
