Caching of web service requests

A computer implemented method, system, and computer program product for generating a response to a web service request from a requester. In response to receiving a web service request, a web service controller calls a business logic interface associated with the request. The output of the business logic interface can either be obtained from a cache or derived from the business logic interface. A customizable template is executed to generate the response to the request. A determination is made as to whether the response comprises a set of cacheable content. In response to determining that the response comprises a set of cacheable content, the set of cacheable content is stored in the cache. The response is sent to the requester.
