Hi Walter,

I agree with you that the logical solution would be to store them together
in the UA preferences.  From what I understand, though, the major UAs
would likely not implement this, though.  So, servers are keen on
Adrian's/Ian's latest proposal which removes the dependence on Uas.  I'm
operating under the assumption that in order to have UGEs work in
practice, we have to remove reliance on the UAs.  Is my assumption not
shared amongst others?

Also, how can a server detect loss of a previously granted exception?  If
a server can detect the loss of a previously granted exception, in your
cookie-based approach can the server re-write the exception?
