HTTP/1.1 requires that Via be sent by proxies.  If privacy is a concern,
the actual hostname of the proxy can be replaced by a unique pseudonym,
but that should be a configurable option.  I would like to see this
implemented by the proxy, even with its current HTTP/1.0 status, since
being too transparent will lead to transparent infinite loops in the
request chain and a raft of misidentified bug reports.
