title: express how to make the route catch prefix
body: <p>I am using node with express. I have the following route:</p>
  
  <pre><code>app.get('/facebook/auth/callback', passport.authenticate('facebook', { failureRedirect: '/auth-failure' }, users.authSuccess));
  </code></pre>
  
  <p>How do I make this route match to:</p>
  
  <pre><code>http://localhost:3000/facebook/auth/callback?error_code=2102&amp;error_message=User+is+not+a+test+user+owned+by+the+application#_=_
  </code></pre>
  
  <p>(for some unknown reasons this route doesn't catch the url)</p>
