One of those distributed container management systems like Kubernetes normally has some integrated way of handling **replication of containers** while still supporting **load balancing** for the incoming requests. All at the **cluster level**.

    `Cache.urls()` would prevent in-flight entries from being written.

 *  Fix: Acknowledge and apply inbound HTTP/2 settings atomically. Previously we had a race where we
