title: .htaccess allow both www and non-www
body: <p>I have subdomain that can be accessed like <code>https://sub.example.com</code> but if I do <code>www.sub.example.com</code> it returns</p>
  <blockquote>
  <p>Server Not Found</p>
  </blockquote>
  <p>Currently <strong>without any <code>.htaccess</code> file</strong>  if I type <code>sub.example.com</code> it goes to <code>https://sub.example.com</code> I want the same thing happen if I type <code>www.sub.example.com</code></p>
  <p><strong>Any idea?</strong></p>
