A method for responding to a content retrieval request at a server may include receiving the content retrieval request from a computing device; detecting, at a device aware controller, at least one device capability of the computing device; setting, at the device aware controller, a rule boundary for the content retrieval request based on the at least one device capability; forwarding the content retrieval request with the rule boundary to a device agnostic controller, wherein the content retrieval request does not include capability information associated with the computing device; receiving from the device agnostic controller at the device aware controller, data corresponding to the content retrieval request with the rule boundary applied; and providing the data with the rule boundary applied to the computing device for presentation on the computing device.
