Resolved! Security rules when ISP is caching?
In looking at outbound traffic I can see quite a bit to a network range owned by my ISP. I'm guessing that it's a cache. The application traffic seems to be what one would expect to be efficiently cached (ms-update, symantec-av-update, http-video, etc).How do you write rules for that? Or is it that, say, Microsoft is taking an ms-update request ...
