The proxied case is a bit trickier to get right. Nottingham suggests some
methods for faulty proxy detection:
http://tools.ietf.org/html/draft-nottingham-http-pipeline-01#section-5 .

Joe and I had some discussion about where we believe the best place for
implementing this sort of faulty proxy detection is. Our inclination was
to keep this out of the protocol stack itself (although we're certainly
open to suggestions!).
  

If a client is going through a faulty proxy, there are two cases to be
dealt with:

(1) The client is going through a transparent faulty proxy (i.e. We don't
have an identifiable host)
(2) The client is going through a non-transparent faulty proxy (i.e. We
have an identifiable host)

For (1), the application might simply disable pipelining entirely.

For (2), it might make most sense for the app to pass in a proxy blacklist
just as it would a standard host blacklist.

Does that seem reasonable?
