The following errata report has been submitted for RFC8555, "Automatic Certificate Management Environment (ACME)". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid6030 -------------------------------------- Type: Technical Reported by: Matt Palmer <mp+ietf@hezmatt.org> Section: 7.2 Original Text ------------- To get a fresh nonce, the client sends a HEAD request to the newNonce resource on the server. The server's response MUST include a Replay- Nonce header field containing a fresh nonce and SHOULD have status code 200 (OK). The server MUST also respond to GET requests for this resource, returning an empty body (while still providing a Replay- Nonce header) with a status code of 204 (No Content). Corrected Text -------------- To get a fresh nonce, the client sends a HEAD request to the newNonce resource on the server. The server's response MUST include a Replay- Nonce header field containing a fresh nonce and SHOULD have status code 204 (No Content). The server MUST also respond to GET requests for this resource, returning an empty body (while still providing a Replay- Nonce header) with a status code of 204 (No Content). Notes ----- RFC7321 s4.3.2, says "The server SHOULD send the same header fields in response to a HEAD request as it would have sent if the request had been a GET". I can't see any rationale for violating this SHOULD in the discussion in the GH issue which introduced the discrepancy in response code between GET and HEAD (https://github.com/ietf-wg-acme/acme/pull/371), thus (IMHO) it violates the tenets of a SHOULD, as "the full implications" do not appear to have "be[en] understood and carefully weighed before choosing a different course" (RFC2119, of course). Instructions: ------------- This erratum is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party can log in to change the status and edit the report, if necessary. -------------------------------------- RFC8555 (draft-ietf-acme-acme-18) -------------------------------------- Title : Automatic Certificate Management Environment (ACME) Publication Date : March 2019 Author(s) : R.
