Hi Paul,
Without knowing much more, a couple thoughts.
First, what is meant by caching is disabled? "Do Not Cache" will tell the ProxySG not to add a site to cache, but it will not stop ProxySG from pulling from cache. "Bypass cache" will prevent a site from being served from cache.
The other thought I have is does the end customer have a Cachepulse subscription? I could see a rule where everything is set to "Do Not Cache" but Cachepulse is updating the most common sites, and if there is no "bypass cache" rule in place, nothing to stop the ProxySG from pulling from cache.
Just throwing that out as a possibility.
Hope that helps!

Subject: Bandwidth Gain
Hi All,
On a pair of SG's running in explicit mode using SGOS 6.7.5.10, we are seeing significant bandwidth gain the in the traffic mix and history statistics, indicating caching is effective. The thing is that caching is disabled for all content in the policy, so I can't really explain what we are seeing and wondered if anyone had come across this.
