They are having a problem whereby documents published via the portal appear to be cached by the proxy, that is, if an existing document is updated then the new version is often not seen by users who access the portal via the proxy - they continue to see the old version. Users who bypass the proxy always see the updated document.

I would recommend you to read the "Caching Tutorial for web masters"
document <url:http://www.mnot.net/cache_docs/>. This document explains in
detail how the whole picture pulls together and what should be done to
applications/servers to work properly in precense of caches.

It also explains many of the common errors which is often done, allowing
you to not repeat the same stupid mistakes.

This document should be mandatory reading for anyone who designs a web
system for publishing content.
