How to I reconfigure BM not to cache web pages of an internal webserver that
is not available to the internet, it's only use if for Interanet client on
the private network side.

This problem arose from documents updated on the internal web server not
showing up proper on the web page, if I turn proxy off at the workstation
and access the internal web page, the documents show proper but with proxy
enabled the documents show a previous revision being cached by border
manager.
