public sealed class RequestMirrorPolicy : IMessage<RequestMirrorPolicy>, IEquatable<RequestMirrorPolicy>, IDeepCloneable<RequestMirrorPolicy>, IBufferMessage, IMessage
Reference documentation and code samples for the Compute Engine v1 API class RequestMirrorPolicy.
A policy that specifies how requests intended for the route's backends are shadowed to a separate mirrored backend service. The load balancer doesn't wait for responses from the shadow service. Before sending traffic to the shadow service, the host or authority header is suffixed with -shadow.
The full or partial URL to the BackendService resource being mirrored to. The backend service configured for a mirroring policy must reference backends that are of the same type as the original backend service matched in the URL map. Serverless NEG backends are not currently supported as a mirrored backend service.
