Combine WebResource.axd CSS requests
<p>I have developed some ASP.NET server controls which include their own javascript and css files.  A lot of these controls use jQuery extensions which, as you know, often include their own css files.</p>

<p>I'm using Telerik's RadScript manager which combines the javascript like a boss.  However, I'm using the AjaxToolkit's ClientCssResource attribute to include the css files in my server controls, and I have noticed that the CSS files are not getting combined at all.  My pages have 10-15 WebResource.axd requests for css files for my server controls.   </p>

<p>Everything I find only is about combining javascript, and nothing tells me how I can combine the CSS files.   Does anyone know if there is a way to combine the CSS dynamically (I don't want to manually combine as each page might use a different subset of the server controls)?</p>
