title: Specify pem file with Angular 2
body: <p>In my Angular 2 app, I'm using the http service to make a GET call to my website.  That site is locked down via certificate funkiness.  If I were making the GET call via curl I'd pass in the --cert flag and specify my .pem file to make the connection.  </p>
  
  <p>How do I do that same thing with this http.get call?</p>
