CT - interacting with the user

Proxies by their nature don't generally interact directly with the user. I  
think it is worth explaining what we mean by "inform the user", "advise  
the user", "allow the user to..." etc.

One approach is for the proxy to ship content explicitly to the user  
(instead, presumably, of what the user actually asked for). Another is to  
make flags available to the user agent which is accessing the proxy (e.g.  
generating 300 responses, vary headers, or the like) which would allow the  
UA to do whatever it normally does that allows the user to make choices.

This question is important because at the moment we seem to be implying  
requirements on the proxy which either make assumptions about the UA, or  
contradict the goal of letting the user simply go to the content they  
asked for (which is the service proxies generally provide, trying to be if  
not transparent in teh terms of the document then at least as invisible as  
possible).

cheers
