Does the proxy forward 1xx responses when
searching or generate its own, e.g., a new one for each unique string?
Disadvantages are the Implosion and possible confusion because of
interleaving; advantage is additional information at the caller as to
what's
happening.

Suggested resolution: Proxies should optionally be allowed to forward
all 1xx responses.
