Important Facts

  • A 200 response always has a payload, though an origin server MAY generate a payload body of zero length or empty payload.
  • If server does not want to send any payload in response, then it should send HTTP status 204 (No Content) instead.
  • By default, 200 (OK) response (header and payload) are cacheable. If chaching needs to be overridden then response must include cache respective cache headers.
