Thanks for eyplaining, Willy,
we tested everything so far (with version 1.4.4) and we discovered a
strange behaviour:
We have seven back-end servers and without "hash-type consistent", all
are being used equally by haproxy. But as soon as we activate
"hash-type consistent" only two of the back-ends are being used, the
other five won't receive any requests anymore.
Still used are back-end one and seven, none of the others.
This is how the part of the config looks (pretty much standard):
global
log 127.0.0.1 local7 notice
maxconn 4096
daemon
user haproxy
group haproxy
defaults
log global
mode http
option httplog
option dontlognull
