ABSTRACT:
Data is served from a data source to a user. The data source has a plurality of pre-defined user groups. A request is received from the user for the data from the data source and a cache key corresponding to the requesting user is generated based on a set of the user groups of such user. The generated cache key represents access rights for the user based on the set of the user groups of the user. Thereafter, it is determined whether any data that satisfies the request is stored in the cache with the generated cache key.
