I need something I can pay a fair amount for, that provides DNS service and HTML and file asset acceleration. I want to switch the proxy on, let it offload as much of the traffic from the original source server as possible, and forget about it. My clients should be able to control their DNS on their own, on let us do it for them. They should only have access to their own domains.
