Currently there is no easy way to achieve this within the proxy
configuration, however it is being worked on.
An approach might be to modify the backend, so that responses for these
users are rendered uncacheable. A full guide to the conditions which
determine cacheability is at;
http://httpd.apache.org/docs/2.1/caching.html#overview
Forcing the backend to include a "Vary: *" header for such responses
would give the desired behaviour for example.
