title: Tracking Multiple Domains with Google Analytics in same code
body: <p>I have portal which behaves like multiple portal. 
  The portal code base is same but for all sites but content is based on which url or domain you came across.
  Currently i am able to track my domain</p>
  
  <blockquote>
    <p>example.com</p>
  </blockquote>
  
  <p>and also subdomains like </p>
  
  <blockquote>
    <p>a.example.com, b.example.com</p>
  </blockquote>
  
  <p>. But i want to also track </p>
  
  <blockquote>
    <p>anotherexample.com</p>
  </blockquote>
  
  <p>which also point to same domain. How can I do?
  Any suggestions?</p>
