With the introduction of this feature, users instruct load balancers to forward traffic from within the Cloud Load Balancing data processing path through gRPC to user-managed or partner-hosted applications. These applications can apply various policies or functions, such as header or payload manipulation, security screening, or custom logging on the traffic before returning the traffic to the load balancer for further processing.
