title: How to keep the same URL for both versions - mobile and desktop?
body: <p>Is it possible to have the same URL for both the mobile and desktop versions? I don't mean a responsive site, but a completely separate mobile site with his own index.php, css and js files. </p>
  
  <p>I would like the URL to remain unchanged and if the user enters from a mobile device to the website <code>example.com</code> it redirects to the appropriate index of a mobile version but the URL still remains <code>example.com</code> not <code>m.example.com</code>. </p>
  
  <p>How can that be achieved?</p>
