Do not cache responses that do not have an explicit expiration time (s-maxage or max-age Cache-Control directives or Expires header) or a validator (ETag or Last-Modified headers) anymore, as suggested in RFC 7234#3. The TX_FLAG_IGNORE flag is used instead of the TX_FLAG_CACHEABLE so as not to change the behavior of the checkcache option.
