    I've enabled the CDN support.

    Unfortunately look at all the http request that get generated on one of my pages.
    I used to have enable styles and javascript files set to true, but with the CDN, that's ignored.

    Does the benefit of using a CDN outweigh the cost of making all these HTTP request?

    I like the CDN for a couple reasons ...

    1) Expires headers on all those files, so while there's a lot...they wont need to be re-downloaded for something like 30 years (cant remember the exact far-future date).  So while there is an initial cost (more requests), you're also allowing your sites files to come down faster because they aren't waiting on the telerik chunks to D/L from your domain as they're coming from teleriks domain in parallel

    2) Doesn't spend my bandwidth downloading them :)
