A method and system for caching content, such as content requested from a server on the World Wide Web. Requests for dynamic content are forwarded directly to a content server to avoid caching data that might only be used once. Requests for static content are forwarded to a hot or a regular cache depending on the frequency at which the content is requested. When a hot cache does not contain the content, it forwards the request to the forwarder which then forwards the request to a regular cache. When the regular cache does not contain the content, it requests the content from the forwarder which then forwards the request to a content server. There may be more than two layers of cache.

Method and system for distributing requests for content

A system for accessing network services includes a plurality of resolvers including a root resolver and a secondary resolver, each resolver arranged to perform actions comprising determining a set of service locations based at least in part on the service and an address associated with a client. the system includes an intermediate device that manipulates scores returned by a set of resolvers of the plurality of resolvers, wherein the root resolver is further arranged to combine sets of the determined service locations and return a combined set of service locations to the client, and wherein at least one resolver of the plurality of resolvers employs an algorithm that is different from an algorithm employed by another resolver of the plurality of resolvers, wherein each algorithm is employed to determine scores of service locations, wherein the combined set of services locations comprises the scores of service locations.

Method and system for accessing network services

A method and system for accessing network services. A client sends a request for a service. The request includes an address of the client. One or more resolvers receive the request for a service. The one or more resolvers determine at least one service location to return to the client based at least partially on the service requested and the address of the client. The at least one service location is then returned to the client. The service locations returned to the client may also be based on a policy, user preferences, client preferences, or client characteristics.
