Ok. I did find one small issue. Should the draft give explicit mention
of returning an HTTP 501 for searches not supported by a server?
[JS] Section 1 of RFC 9082 says, "Servers MUST return an HTTP 501 (Not Implemented)
[RFC7231] response to inform clients of unsupported query types." If that strictly
applies to the query types listed in RFC 9082, then an explicit mention in this draft
makes sense.
Sorry but it's not clear to me the meaning of "unsupported query types".
In RFC7231 HTTP 501 is used to signal a client that it requested a
method on a given resource the server doesn't implement :
Section 4.1
The set of methods allowed by a target resource can be listed in an
Allow header field (Section 7.4.1). However, the set of allowed
methods can change dynamically. When a request method is received
that is unrecognized or not implemented by an origin server, the
origin server SHOULD respond with the 501 (Not Implemented) status
code.
and Section 6.6.2
The 501 (Not Implemented) status code indicates that the server does
not support the functionality required to fulfill the request. This
is the appropriate response when the server does not recognize the
request method and is not capable of supporting it for any resource.
The only HTTP method available on RDAP search endpoints is GET so I
don't think we need to add text to clarify it.
In the case the client requests for an endpoint that is not supported,
the HTTP code to be used is 404 (Not Found).
Section 6.5.4.
The 404 (Not Found) status code indicates that the origin server did
not find a current representation for the target resource or is not
willing to disclose that one exists.
The remaining case to handle is when the client requests for a supported
endpoint but the server policy restricts the usage of the predicates in
the reverse search and the draft have already addressed it.
Which "unsupported query types" are you thinking about ?
Best,
Mario
