When the client's content distribution network (CDN) is a primary CDN for the content provider providing the requested content, redirecting the client to a server within the client's content distribution network. When the client's CDN is not a primary CDN for the content provider but the client's CDN has a content peering relationship with a primary CDN for the content provider, redirecting the client to a server within the client's CDN.
