The client could be sending chunks precisely because it's designed to
work with a proxy that is known to accept them.  That doesn't imply
any knowledge of the backend(s) proxied, which might be anything up to
and including the 'net in general.

Also bear in mind that we were discussing (also) the case where the
request came with C-L but an input filter invalidated it.
