    -- make ClientHTTP (webserver mode) support transfer-encoding
       "chunked" PUTs, when PUTs are already enabled.  useful
       for things like MogileFS, where writing clients may not
       know the final length ahead of time to predeclare in the
       Content-Length request header.

    -- Add the client_ip to the X-Forwarded-For header when the
       upstream is "trusted" (Ask Bjoern Hansen).
