Definitely make this the front page, made things a lot clearer. It could still use work, though: it still feels a bit vague on how much its oriented toward caching (which I really need to know as it could potentially require changes in a web app) and security (because I'm really confused as to why someone would want to depend on the caching proxy layer for XSS protection).

Also, this line really put me off:

I don't think anyone wants one entity having the ability to re-route a significant proportion of http traffic!
