title: URLs for goals when sign up page is on a subdomain
body: <p>Website: </p>
  
  <ul>
  <li>example.com</li>
  </ul>
  
  <p>example.com Sign up complete page: </p>
  
  <ul>
  <li>secure.example.com/secure/thank_you?longstringhere</li>
  </ul>
  
  <p>In Google Analytics (UA) I'd like to set up goals, where a person who sees the sign up page is a converted visitor.</p>
  
  <p>From within the admin section of GA, when setting up goal details as a destination, I tested:</p>
  
  <pre><code>Destination Regular Expression: secure/common/callback
  Destination URL equals: /secure/thank_you
  Destination begins with: /secure/thank_you
  When attempting to verify the result with all 3 variations the result is 0.
  </code></pre>
  
  <p>Is this because of the subdomain? It's all I can think of and I don't know how to change my regex to fit with that?</p>
