This doesn't happen by default as the `Response` is initialized with one by default but any class extending from it can adjust that. Technically speaking, it's not disallowed to have no `cache-control` header set.Want me to add a test for that? :)Commits-------31591c3 [HttpFoundation] Fixed type mismatch
