Hello Acme  list,

I want to use an ACME client to get a new certificate without taking down my existing web services that are using a port 443 (with a self-signed certificate or a certificate issued by another CA).

I therefore request that the Response payloads for Challenge messages that will later lead to server-to-client callback, such as Simple HTTP and DVSNI, include an optional  port number. The ACME server would then use the optional port when calling back to the client.  If no optional port is specified, the server would use port 443.

Thanks,
Bruce
