Is there a way to let DNN 4.3.4 serve different css stylesheet files based on the browser type making the request? I tried altering default.aspx.vb and added a browser capabilities test, but this works only the first request, probably a caching issue? Ideally I'd like to server skin_ie.css to IE and skin.css to all other browsers.

Thanks for the reply,

Ideally I'd like to use conditonal comments, but they only work in html and not in CSS. I only know of CSS hacks, which also cause problems, for example with IE7. If anyone knows of a robust css method I'd like to know about it since I'd much rather add it to the css instead of altering default.aspx(.vb)
