So no HTTP redirects at all AFAIK. They probably do this at the first level URL to find the closest master site, but I know that there are specific URLs that get generated which actually refer by name to the closest cache server. I know this because Belgacom Skynet (my former employer) was the host to the first set of Akamai servers in Belgium, and we learned a lot about how they functioned. Kind of like doing anycast for the Global Director (or similar device), then having it do a redirect to the closest load-balancing system to handle the actual traffic. -- Brad Knowles, Do you hate Microsoft?
