It doesn't really do anything like that today, but it would need to do the
equivalent of:

  1 - marking the current connection to get closed on end-of-use
  2 - set the easy handle to "try next connection with TLS disabled", which we
      currently can't. It must not just alter any option that the user has set
      since repeated uses of this handle must still do right.
  3 - set the URL field to do a second request to the same URL. This method is
      already done by the multi-pass HTTP auth methods etc.

Yes, they do. And I think that is a fair expectation in most situations.
