    This is where it gets fun using document.domain.

    example.com/test.html page’s html

    <script>document.domain = "example.com";</script>
<iframe src="subdomain.example.com/domain.html" style="display:none"></iframe>

<script>
  /* make ajax calls or access iframe of the subdomain*/
</script>

    HTML for subdomain.example.com/domain.html [page in iframe]

    <html>
  <head>

  </head>
  <body>
    <script>document.domain = "example.com";</script>
  </body>
</html>
