A method for delivering resources in a distributed computing environment, wherein at least a first resource and a second resource are associated with a content provider, and wherein the first resource references the second resource via a first uniform resource locator (URL), the first URL having a first domain name that resolves to a server associated with a domain of the content provider. The second resource is associated with a domain name that resolves to a content delivery network (CDN) formed by a plurality of repeater servers. The domain of the CDN may be distinct from the domain of the content provider. Responsive to a request that causes the first resource to be served to a client from an origin server associated with the content provider's domain, the second domain name in the second URL is resolved to identify a repeater server in the CDN's domain from which to serve the second resource to the client. If a copy of the second resource is already replicated on the identified repeater server, then the copy of the second resource is served to the client from the identified repeater server; otherwise, the second resource is replicated on the identified repeater server and the copy of the second resource is served to the client from the identified repeater server.
