CDN

[pmeenan]

When the optimization checks are done Pagetest does a DNS lookup for the host name (as well as a reverse-lookup on the IP) and checks to see if the hostname is a CNAME to a known CDN.

This way we can maintain a short list of known CDN domains and get broad coverage. If you're using a CDN that isn't detected just shoot me a note and I can get it added to the next release.

Thanks,
