Multiple versions of a service can be supported by taking advantage of the fact that version information can be included in any received request. Using the version information, an appropriate template can be determined up front to be used for the response. In instance of the template can be filled in using appropriate data sources, as may be specified using metadata in the template itself. Information can be processed in parallel, respecting any data dependencies specified by the template metadata. Once the instance of the template is filled, the response can be finalized and sent to the source of the request.

One embodiment of the present invention provides a system that facilitates serving data from a cache server. The system operates upon receiving a request for the data at the cache server. The system first determines if the request requires access control, and also if the data is available in the cache. If the request requires access control and if the data is available in the cache, the system sends an authorization request to an origin server. Upon receiving a response from the origin server, the system determines if the response is an authorization. If so, the system sends the data to the requester.
