title: Forcing users to use SSL on main domain and sub domain. WHMCS
body: <p>I have two major links that have SSL certificates,<br/>
  www.example.com <br/>
  billing.example.com<br/>
  And I want to force users to use SSL on both of them,<br/>
  <a href="https://www.example.com" rel="nofollow">https://www.example.com</a><br/>
  <a href="https://billing.example.com" rel="nofollow">https://billing.example.com</a><br/><br/></p>
  
  <p>I'm using WHMCS and when I put it in the settings to use billing.example.com it it acts like it's on www.example.com</p>
  
  <p>I tried a few different things with .htaccess but none worked.</p>
