  • Patent number: 10594657
    Abstract: Methods, non-transitory computer readable media, network traffic management apparatuses, and network traffic management systems that provide parameterized sub-policy evaluation for fine grain access control implemented by determining when there is a result for one of the plurality of sub-policies being evaluated for a received request for a resource during a session. The result for evaluation of the one of the plurality of sub-policies for the received request is used when the determination indicates the result is stored for the session. The one of the plurality of sub-policies is executed on the received request to obtain the result when the determination indicates the result is not stored for the session. The result for the one of the plurality of sub-policies from this execution is stored for the session.
