[OpenID] Automating the user's selection of OP

[Andrew Arnott]

That makes sense.  I knew it was a different although the idea is similar.
User agents don't let you make cross-site HTTP calls however, which may
block the implementation of your idea.  My control works with a concert of
hidden iframes and coordinated redirects between the RP and OP.  But I think
you can't rely for any redirects from an OP doing what you're suggesting, so
any iframe you create will just sit there, and since it's a cross-site
iframe your javascript will never get any information back from it,
including the HTTP status code I believe.

Don't let me stop you from trying, but I just will be surprised if it will
work.

Didn't you mention (or discuss on a thread) sometime back the idea of
emitting links to OPs using javascript, then sniffing whether they were
"visited" links or not in order to see which OPs the user has been to and
thereby guess which OPs are most effective to display to the user?
