Varnish only supports ETags "in front" that is, only when a client
sends us an ETag will we respons correctly. Towards the backend Etags
are not supported although I think there are patches floating around
that might address that. If I recall correctly Slink and some
Rackspace people where eager to see ETags in Varnish.
