Jamie, Cookies dont need state replication.
Source IP has a new replication feature, example here: peers mypeers peer haproxy1 192.168.0.1:1024 peer haproxy2 192.168.0.2:1024 peer haproxy3 10.2.0.1:1024 backend mybackend mode tcp balance roundrobin stick-table type ip size 20k peers mypeers stick on src server srv1 192.168.30:80 server srv2 192.168.31:80 BTW: LVS can easily do session replication just use: ipvsadm --start-daemon master ipvsadm --start-daemon backup On 15 March 2011 14:45, Jaime Nebrera <jnebr...@eneotecnologia.com> wrote: > > Hi all list members, > > I'm wondering if its possible to share the connection affinity / state > between a couple of HA proxies, in such a way, in case of failure the backup > server will redirect the user to the same end server as it was using when > going through the main haproxy. > > I'm aware this can be done with LVS and with netfilter too (for connection > tracking. not affinity relted though), but dont know if its possible with > haproxy. > > Is it? how?
