Cacheable
A response is considered cacheable when the status code is one of 200, 203, 300, 301, 302, 404, 410. This range of status codes can be extended with additional_cacheable_status or overridden with match_response.
Safe
A request is safe if its HTTP method is GET or HEAD. Safe methods only retrieve data and do not change the application state, and therefore can be served with a response from the cache.
