not support Cache-control because cache-control is intended for proxy servers.
The HTTP/1.1 spec says "Responses to this method [POST] are not cachable, unless the response includes appropriate Cache-Control or Expires header fields". So I don't think the sender of the request or response must include a header "Cache-control: no-ca
che" in order to prevent caching from occurring.
Also, "Cache directives MUST be passed through by a proxy or gateway application, regardless of their significance to that application, since the directives might be applicable to all recipients along the request/response chain". So Cache-Control will be
passed through proxy servers to an origin server containing IPP support.
What does "support" mean in this context?
