<h1>Welcome to the IFRAME TEST</h1>

<p>
  In order to properly test this, you should serve this page at a different
  address (even just a different port) from our application stuff. Otherwise
  you won't get the full cross-origin restrictions.

<iframe id="member-form" src="//localhost:8080/self-serve/combo" width="100%" scrolling="no"></iframe>
<script type="text/javascript" src="//localhost:8080/js/self-serve-parent.js"></script>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>

<p>
 This is the bottom of the parent page.
