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 retries 3 option redispatch contimeout 5000 clitimeout 50000 srvtimeout 50000 listen context 0.0.0.0:80 mode http log global balance url_param site hash-type consistent option forwardfor option httpclose server context1 10.104.27.149:9100 check server context2 10.217.9.191:9100 check server context3 10.104.41.152:9100 check server context4 10.217.25.253:9100 check server context5 10.104.29.171:9100 check server context6 10.104.23.224:9100 check server context7 10.104.25.192:9100 check
