1. A method comprising:
in a network security system interposed between clients and a cloud application:
receiving an incoming request from a client directed towards the cloud application;
in response to determining that the incoming request lacks metadata for enforcement of a policy, transmitting a synthetic request to obtain the metadata from the cloud application;
receiving a response to the synthetic request, wherein the response provides the metadata; and
applying the policy to the incoming request based on the metadata.
