The technology disclosed describes a system. The system comprises a network security system interposed between clients and cloud applications. The network security system is configured to process an incoming request from a client and generate metadata. The network security system is further configured to transmit the incoming request to a cloud application. The network security system is further configured to configure the metadata to expire after an expiration window. The network security system is further configured to receive, after the expiration window, a further incoming request from the client. The further incoming request is directed towards the cloud application and subject to policy enforcement that requires the expired metadata. The network security system is further configured to hold the further incoming request and transmit a synthetic request to the cloud application. The synthetic request is configured to retrieve the expired metadata from the cloud application.
