Hi, Could ATS in reverse proxy mode be configured such way that it would never try to revalidate from source? It is known that in our case, object never changes (and is never refetched from source) and it is desirable to avoid any source validation. Validation verification adds significant overhead and we need to avoid it. Response to client with TCP_REFRESH_HIT would take 100-200ms instead of 0-10 in case of direct local TCP_HIT.
I've configured following: dest_domain=.*.source.tld action=ignore-no-cache dest_domain=.*.source.tld revalidate=9999d dest_domain=.*.source.tld ttl-in-cache=9999d CONFIG proxy.config.http.cache.when_to_revalidate INT 3 CONFIG proxy.config.http.cache.required_headers INT 0 But i still get TCP_REFRESH_HIT even when 9999 days have not passed (obviously). NB! ATS is used as internal cache and our 'client' never explicitly requests revalidation. Thanks, Veiko
