Hi,
I must first thank the following for their speedy replies:
Stanley Horwitz <stan_at_astro.ocis.temple.edu>,
Bob Vickers <R.Vickers_at_dcs.rhbnc.ac.uk>,
Jim Bostwick <Jim_Bostwick_at_cargill.com>
I my original (and admittedly rather misleading) poster I ask who I can
enforce all users to use the proxy cache, for example implement global
preferences (not individual). Bob Vickers hit the nail on the head and
suggested using a (k)shell wrapper around Netscape. Bob gracefully provided
an example script which can be customised as required. Thanks!
