title: Subdomains not working when www is added?
body: <p>I have purchased My Domain name from one registrar &amp; hosted in another hosting company.
  I have created a sub domain from my hosting domain manager lie <code>http://subdomain.domain.com</code> and it works fine. But when someone types in <code>www.subdomain.domain.com</code> the site is not working.</p>
  
  <p>Do I need to make changes in my DNS Manager of hosting CPanel or DNS Manager of my Domain CPanel?</p>
  
  <p>Also What all Records I need to add ( like A Record or CNAME) to redirect <code>www.subdomain.domain.com</code> to <code>subdomain.domain.com</code>.</p>
  
  <p>I don't want to see <code>www</code> for my subdomain, but only wants to get redirected to <code>subdomain.domain.com</code>.</p>
