If a 1.0 proxy forwards a request and gets back a 1.1 response, it is
allowed to switch to tunnel behavior and forward the exact response to
the client, 1.1 version number included.  So what you have seen need
not be a bug in the CERN 3.0 proxy, it may be the CERN 3.0 proxy
switching to tunnel behavior.

On the other hand, if you are sure you are getting the 1.1 response
from CERN proxy cache memory, without the origin server being
contacted, then there _is_ a bug in the CERN 3.0 proxy.  Does the Date
header change in subsequent responses?
