I look into the diagram at https://docs.trafficserver.apache.org/en/latest/developer-guide/plugins/hooks-and-transactions/index.en.html#hooks Can we specify whether a content is cacheable or not in TS_HTP_READ_RESPONSE_HDR_HOOK? > > Agreed.

No, I don't need the separate two configs for my use case. I would like to achieve using only Cache-Control: s-maxage and ignore other headers to determine a content is cacheable. How about adding a value to proxy.config.http.cache.required_headers? https://docs.trafficserver.apache.org/en/latest/admin-guide/files/records.config.en.html#proxy-config-http-cache-required-headers 0 = no headers required to make document cacheable 1 = either the Last-Modified header, or an explicit lifetime header, Expires orCache-Control: max-age, is required 2 = explicit lifetime is required, Expires or Cache-Control: max-age 3 (new value) = explicit lifetime is required, Cache-Control: s-maxage (Expires or Cache-Control: max-age are ignored).
