Heroku doesn't support all forms of rails caching, because it's a read-
only filesystem. ETags usually work well, but a lot depends on how
you're generating them. I just posted over on Rails Talk about the
fact that fresh_when() doesn't support collections, for example.

You'll definitely need to provide more information about how you're
generating your ETags to get useful help. I can assure you, though,
that when you do it right, Varnish and the user clients see the
correct hashes.
