     * The 304 (Not Modified) status code indicates that a conditional GET or
     * HEAD request has been received and would have resulted in a 200 (OK)
     * response if it were not for the fact that the condition evaluated to
     * false. In other words, there is no need for the server to transfer a
     * representation of the target resource because the request indicates that
     * the client, which made the request conditional, already has a valid
     * representation; the server is therefore redirecting the client to make
     * use of that stored representation as if it were the payload of a 200 (OK)
     * response.
     *
     * The server generating a 304 response must generate any of the following
     * header fields that would have been sent in a 200 (OK) response to the
     * same request: Cache-Control, Content-Location, Date, ETag, Expires, and
     * Vary.
     *
     * Since the goal of a 304 response is to minimize information transfer when
     * the recipient already has one or more cached representations, a sender
     * should not generate representation metadata other than the above listed
     * fields unless said metadata exists for the purpose of guiding cache
     * updates (e.g., Last-Modified might be useful if the response does not
     * have an ETag field).
     *
     * Requirements on a cache that receives a 304 response are defined in
     * Section 4.3.4 of [RFC7234]. If the conditional request originated with an
     * outbound client, such as a user agent with its own cache sending a
     * conditional GET to a shared proxy, then the proxy should forward the 304
     * response to that client.
     *
     * A 304 response cannot contain a message-body; it is always terminated by
     * the first empty line after the header fields.
