Abstract
Mechanisms and techniques provide a system that operates in content routers and content engines in peered content distribution networks. Using domain name specifications associated with the content distribution networks, a content router may provide a forward domain resolution response to redirect a domain resolution request to another peered content distribution network. If a secondary content router determines that a content request is not to be processed in its content distribution network, it may respond with: a reflected domain resolution response that is returned to a primary content router or a forward domain resolution response. Content engines may also reflect content requests back to the primary content router by providing: a reflected redirect content response to a client, or a redirect forward content response that must be resolved. After termination of a peering relationship, a reflection continuation period may be defined during which secondary content networks provide reflected or forwarded responses.
