I would defenitely not use that aggressive caching. It will cause a lot
of pages which is not intented to be shared to be cached as shared
pages.

The above rules makes Squid have much more aggressive caching than the
default.

It may well be caused by the combination of your aggressive caching
rules, and probably combined with the fact that many of the application
developers not yet make use of "Cache-control: private" to mark pages
which is intended for a single user only.

I defenitely do not recommend using a min age in refresh patterns unless
you know what you are affecting. I am also not very fond of
reload-into-ims.
