There is currently no keyword to allow that. I remembered someone already asked for this, and just realized it was you :-) See Willy's answer : http://www.formilux.org/archives/haproxy/1009/3865.html > I was thinking that I could stop a server being entered in to the > persistent table like this: > > r...@vm11:/etc/haproxy# cat haproxy.cfg > (...) > backend B1 > acl no_persist_backup dst 192.168.30.47 > mode tcp > option persist > stick-table type ip size 10240k expire 30m > stick on src unless no_persist_backup > stick on src if !localhost > balance leastconn > server R1 192.168.30.201:80 weight 1 check port 80 inter 2000 rise 2 > fall 3 > server R2 192.168.30.202:80 weight 1 check port 80 inter 2000 rise 2 > fall 3 > server backup 192.168.30.47:80 backup > option redispatch > option abortonclose > > but alas , my efforts seem in vain. I am doing something wrong ? The "dst" acl can't work in your case because if the server is already known, it means that the stick rule has already been applied. But maybe there's an alternative solution : you could split your backend in 2 parts, one for the main servers, and one for the backup ones. Then, your frontend can use the backup backend if the main one has no UP servers. Which could look like : ... frontend F1 bind 192.168.35.201:80 default_backend B1 acl B1_DOWN nbsrv(B1) 0 use_backend B1_backup if B1_DOWN mode tcp backend B1 mode tcp option persist stick-table type ip size 10240k expire 30m stick on src if !LOCALHOST balance leastconn server R1 192.168.30.201:80 weight 1 check port 80 inter 2000 rise 2 fall 3 server R2 192.168.30.202:80 weight 1 check port 80 inter 2000 rise 2 fall 3 option redispatch option abortonclose backend B1_backup mode tcp balance leastconn server backup 192.168.30.47:80 backup option abortonclose -- Cyril Bonté
