CacheHeadersMiddleware class final

Laravel's cache.headers middleware (SetCacheHeaders):

router.get('/catalog', catalog).middleware(const [
  'cache.headers:public;max_age=3600;etag',
]);

On successful GET/HEAD responses with a body it sets Cache-Control from the options (public, private, max_age, s_maxage, must_revalidate, no_cache, no_store, no_transform, proxy_revalidate, immutable, stale_while_revalidate, stale_if_error), ETag (etag: a hash of the body) and Last-Modified (last_modified: a Unix timestamp or a date), and answers 304 Not Modified when If-None-Match (or, without it, If-Modified-Since) shows the client's copy is current. Headers are written as Symfony writes them for Laravel: directives sorted, private added when neither public, private nor s-maxage is given.
