oh - this is a good thing?

The problem with this is that cache's are not very controllable,
and they are a significant problem for applications that must
maintain tight control over the currency of data in the client.
The cache doesn't fully understand the semantics of the data,
so participates badly in the dynamics. This is a good reason
to tunnel, in practice, to keep cache's out of the picture.
(and since proxies actually seem to ignore http guidelines
in the field, it's doubtful that that something more
challenging can be made to work)
