title: Apache reverse proxy set up SSL certificate
body: <p>We need to set up a secure certificate on an Apache reverse proxy.
  We've been advised that we need to use a virtual host directive.</p>
  
  <p>I've looked these up in the O'Reilly book bit can't find any examples that pick up https specifically.</p>
  
  <p>Does anyone have any examples of config snippets to do this?</p>
