title: Defining multiple Express.js routes using path parameters
body: <p>How can I make Express.js distinguish from the paths "/1.1.1" and "/login" ?</p>
  
  <p>I am using the following code:</p>
  
  <pre><code>app.get('/:x?.:y?.:z?', function(req, res){
  
  ...
  
  app.get('/login', function(req, res){
  </code></pre>
