    Abstract: A network includes a first tier of servers, a second tier of servers and a third tier of servers. The first tier of servers comprises a plurality of primary servers capable of responding to requests. The plurality of primary servers includes at least one dynamic server having a load share characteristic that is dynamically altered during a first period in time and at least one static server having a constant load share characteristic during the first period in time. The second tier of servers includes at least two first layer overflow servers. Each of the first layer overflow servers is configured to provide response duties in the event that one or more of the primary servers is unavailable or overloaded. The third tier of servers comprising at least two second layer overflow servers. Each of the second layer overflow servers is configured to provide response duties in the event that one or more of the primary servers is unavailable or overloaded and one or more of the first layer overflow servers is unavailable or overloaded.

    Abstract: A computer-implemented method, operable in a content delivery network (CDN) including a plurality of cache servers and domain name servers. At a cache server in the CDN, a first domain name is obtained, the first domain name being associated with a client request for a resource from the cache server. One or more values associated with the client request are determined and a second domain name is generated, including information from the first domain name and information relating to the one or more values associated with the client request. The second domain name is provided to the client. A domain name server in the CDN obtains a request to resolve a first domain name; extracts one or more keys and one or more corresponding values from the first domain name, and generates a second domain name based on the first domain name, the second domain name excluding information from the first domain name relating to the one or more keys and the one or more values. The name server resolves the second domain name using at least some of the one or more values extracted from the first domain name.
