Get a list of included CSS files from Page.Header
<p>How do you get a list of CSS files included in a page via code behind.</p>

<p>I see that I can get access to the header with page.Header and the controls with page.Header.Controls, but what is the best way to get the ype of control I'm getting back here.</p>

<p>Ultimately this is to get a list of CSS and JS files that are included and either add or remove to this list via  some items in the HttpContext.</p>
