[SAH] Nit: as alluded to by Jasdip above, RFC 7231 has been obsoleted by
RFC 9110.
The 501 text is 9110 is consistent with 7231, but I don’t think it’s limited to
an invalid method. If the operative text is “the server does not support the
functionality required to fulfill the request”, the response can be returned for
*any* condition in which the server does not support the functionality required
to fulfill the request. It doesn’t say that “the server does not support the
requested method”. I still believe that 501 would be the best response.
After rereading the text, I agree with Scott.
[ML] Just to understand better, daes it mean that an RDAP server should
support additional lookups and searches to those really implemented with the
only purpose of returning an error ?
[SAH] No. The point I'm trying to make is that if a client sends a valid
request to an RDAP server, and that request can't be processed because the
requested functionality isn't supported, then a 501 response is appropriate.
[ML] It's unclear to me what "functionality" (as well as "unsupported
query type") means.
Excluding the HTTP methods and the endpoints, what remains is a
functionality requested by clients through either a query parameter or
an header but unsupported/unknown parameters/headers are simply ignored.
Is there something else ?
