We had this problem for a while.

However it will still quite happily serve a document if one is
requested from it, though it will now not cache it.

A better solution is to deny the cache access to the pages on the internal
web server. This will prevent external users from being able to fetch
internal resources through the cache.

This does mean that internal users using the cache will not be able to
fetch internal pages through it either. The solution for them is to
configure their browsers to go direct for those domains. [Easy to do if
they are using a proxy autoconfig script which you control for instance].
