I was responding to a support call yesterday when I discovered something stunning...
IE9 Tracking Protection was blocking the jQuery library hosted on the Google CDN.
Wow... That's a blow to the whole CDN concept.
Evidently, if a user visits enough separate websites that have a javascript file loading from a unique third-party location (CDN server), IE9 Tracking Protection assumes the javascript file is tracking the user across sites and blocks it. Even if the library is jQuery, and even if the location is the Google CDN.
This is not limited to javascript files. A quick look at my own Tracking Protection settings shows CSS, HTM, PHP, and other assets blocked.
I love the Infragistics CDN and don't want to stop using it... It makes deployment and upgrades sooo much easier.
Is Infragistics aware of this issue, and is there a strategy for response? Does Microsoft have a "whitelist" for sites that host non-tracking assets that Infragistics could join?
Hello Rob,
We are looking into the matter. I have informed my contact at Microsoft about this issue. If you can also post this on their connect site, that will help voice the issue directly to Microsoft team as well.

Hey Taz,
Just checking to see if you have heard anything from your Microsoft contact.
