My CDN server is getting blocked on certain corporate networks. I have added my CDN site to most corporate firewall directory to make sure its categorized correctly and not as a parked domain or other categories which are considered spam by web filtering softwares used by corporates. I guess the reason is that my CDN domain name is not the same as my websites domain name. Why I did this? Because I wanted to use a cookie-less domain for all my static stuff (images/css/js) like everyone else (twitter, youtube). Is there a place which lists all such directories where I can categorize my CDN domain? Is this the best way to do this?
I guess the ROI of this optimization is pretty low and I might consider moving my CDN domain as a sub-domain of my website domain if I dont get any convincing answer to this.

Putting your assets in a separate domain is a common practice, even Server Fault does it (
sstatic.net). I doubt any of your hypotheses are correct, because they would cause problems with too many other legitimate sites. I would contact some of the corporate networks that you're being blocked by (or have the users at those sites do it) and find out why you're being blocked.
