#http_cache_actions(*actions, visibility: :private, max_age: nil, must_revalidate: false, no_store: false, stale_while_revalidate: nil, vary: nil) ⇒ Object

Declare a Cache-Control/Vary policy for the given actions (none = catch-all). Repeatable; rules accumulate (reassigned, never mutated, so subclasses inherit) and the LAST one matching the action wins.
