Request for advice

[Paul Millar <[e-mail]>]

Hi,

I am working within a small team devising a new HTTP-based protocol.  We 
hope to use a /.well-known URI and register this protocol with IANA.

The protocol involves the client issuing a POST request to the server 
and receiving some information back; i.e., this is not a lookup (GET or 
HEAD) request.

As I see it, there are two options:

a.	client issues POST requests directly to a well-known
	endpoint; e.g., /.well-known/<foo>

b.	client issues GET request to /.well-known/<foo-discovery>
	endpoint.  The response describes the location of <foo>.
	The client makes POST request to that URI.

Option a. has some advantages in terms of latency and reduced 
complexity; however, it seems from RFC 5785 that the latter option is 
more in line with the intended use of /.well-known.  Option b. is also 
the approach taken by most other registrants (e.g., OpenID-Configuration)

Would both approach be acceptable, or should we focus on option b. ?

Cheers,

Paul.
