title: Making URL routes case-insensitive for Rails
body: <p>I have a rails route that goes to the </p>
  
  <pre><code>#works for "/profile/abc"
  /profile/:id
  </code></pre>
  
  <p>However, it breaks when the url's id is capitalized</p>
  
  <pre><code>#breaks for "/profile/Abc"
  /profile/:id
  </code></pre>
  
  <p>Anyone knows why?</p>
