Is it possible to run ENTIRE site (not just images, etc) via CDN?

That would make sense, however, for some reason when I re-run the "F" test, I again receive "F", and it keeps showing "2 seconds" no matter when I run the test.

It's not an issue for me, I only wanted to let you know so you know about it. It's likely something no one else is going to experience the same, so likely not worth investigating. :-)
