def etag_matches?(etag) if etag validators = if_none_match_etags validators.include?(etag) || validators.include?("*") end end

fresh?(response)Link

Check response freshness (Last-Modified and ETag) against request If-Modified-Since and If-None-Match conditions. If both headers are supplied, based on configuration, either ETag is preferred over Last-Modified or both are considered equally. You can adjust the preference with config.action_dispatch.strict_freshness. Reference: tools.ietf.org/html/rfc7232#section-6
