+1. In fact the HTTP HEAD request may be the lightest-weight mechanism
proposed yet.
Mike Mell: would this not be even easier than appending the (+active) query
parameter? And avoid the issues about requiring append="qxri"?

Can I ask for a virtual show of hands (-1/0/+1) of people who think
that we should have some kind of very lightweight "ping" for OpenID
service endpoints in time for the OpenID 2.0 spec, preferably using
an approach that works for other kinds of services, too, or not?
I was actually thinking of an HTTP HEAD on the service endpoint,
looking for an HTTP error code (or TCP timeout) or an HTTP success
code. (or a redirect code, in which case the new service endpoint
should be pinged instead).
But regardless of how we'd specify that ping ... should we have such
a thing? Or not? Or "not now"?
Cheers,
Johannes.
