There was also some talk at some point of adding some kind of "policy

cached document which requires authorization, rather than just passing
the entire request on to the backend.
Perlbal does this by having the first backend return a special
"reproxy" header that Perlbal then uses to do the request again to
another backend.
Thats pretty neat. Too bad the LB software I'm using doesn't really
support that (at least not now).
