this is nothing which can be controlled properly by
the client - the server is responsible for caching-headers
and no longer will any proxy cache the file while
the client itself is allowed to do so
this is the only technical clean solution for "people behind a
caching proxy" and the problem a proxy may have cached wrong
you do this typically in any webapplication if you
deliver content only available after login
