on the proxy issue, I will add proper text and resubmit.
Please do NOT without further discussion! Application caching is out
of OPES scope. If we assume HTTP is being adapted, then HTTP already
has all necessary mechanisms that servers can use to get "all
requests", even if their responses are cachable. OPES has nothing to
do with this. We can explicitly say that OPES is not concerned with
application caching if we want to.

Subject: RE: Tracing Draft version-05042003
I see a couple of problems that need discussion. The main
one is the caching proxy issue. If OPES is deployed on a
caching proxy, near the "consumer" end user, then the content
provider endpoint will not receive a request for each use of
the data. The draft seems to ignore this. I think the
server must be provided with a signalling capability to ask
that some notification of the request and the possibility of
OPES services be sent on each use of cached data.
