Actually I didn't because all the clients are running on the same
machines as the haproxy servers. haproxy is used mostly for HA and
abstracting the configuration somewhat (every machine has its private
haproxy and clients there connect to So I guess I can't use
any techniques that usually accompany load balancer detection due to
100% false positive rate.

BTW, I tried messing with $request and $request_uri but without success
(I expected either an empty string or a dash, as in access.log).
