I'm using the very impressive CSS3PIE (http://css3pie.com) library to add support for CSS3 styles in IE6-8. It works fine in versions 7 and 8 and took a lot of pain out of the process.

However, in IE6 no CSS3 styles are shown at all. In fact, looking at the server logs, I can see that IE6 doesn't even download the PIE.htc file, which is necessary for the magic to work. The content type for the file is set correctly as text/x-component, it's referenced by absolute URL, and works fine in IE7 and 8.

I'm using Compass (www.compass-style.org) and the PIE helper which makes the CSS look like this:

#shopping_cart {
  behavior: url("/media/static/css/PIE.htc");
  position: relative;
  border-radius: 10px;
}

I can't figure out what the problem is. Does anyone have any ideas what might cause IE6 to skip the behavior definition altogether?

Cheers,

Jonas
