Thank you for the suggestions, and as everyone pointed out, the
HTTP_REFERER is the issue here not the .phtml format.
@Matthew - I was validating the markup .. the HTML that is rendered
when you view it in a webbrowser. The W3C consortium is attempting to
implement webstandards and practices in how developers create and
display web pages. There are similar standards for CSS as well. I
was simply trying to validate my HTML to these specific standards.
