title: redirecting www.subdomain.example.com to subdomain.example.com
body: <p>I've had some users trying to access a site that is registered as subdomain.example.com with www.subdomain.example.com.</p>
  
  <p>is there some sort of .htaccess rule I can add to redirect people that arrive using www.subdomain.example.com to subdomain.example.com?</p>
  
  <p>Also, do I have to change DNS stuff?</p>
