  title: Fastly Add Cache Settings
  summary: Clone the active version, create a cache settings rule, then activate the new version.
  description: >-
    Cache settings control how long Fastly keeps objects and how it treats
    requests that miss cache. Because they live in service configuration, this
    workflow clones the live version into a draft, creates a cache settings rule
    with a TTL on the clone, and activates the new version. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
