One of the things they explicitly call out is DNS late binding: it doesn't look like they make any exceptions for CDNs and other services that use geo-IP lookups. You could argue that the speed improvements do away with some of the need for CDNs, but there will probably be some other cases that this breaks. You'd want some way for a specific domain to opt-out: perhaps a DNS text record that gets read and indicates that a site shouldn't be optimized?
- igrigorik 14y agoThe IP address of the visitor is forwarded in X-Forward-For, which is a standard header and CDN's can leverage that. Having said that, note that this can actually work against you.. The whole idea is that all of the requests are multiplexed over SPDY between the device and the proxy. So you actually want the closest resource to the proxy, not to the device (and the proxy as close to the device as possible, of course.. :))
