Ok, I can just use "stick on" to put everything into one backend: backend be acl be_sticky ... stick on path if be_sticky balance leastcon server srv1 192.168.0.1 maxconn 100 server srv2 192.168.0.2 maxconn 100 But I have another situation, where I need an additional _per server_ rate limit. I use an extra backend + proxy per server: listen proxy_srv1 bind 127.0.10.1 rate-limit sessions 50 server srv1 192.168.0.1 listen proxy_srv2 bind 127.0.10.2 rate-limit sessions 50 server srv2 192.168.0.2 This works fine, but I want to maintain the total connection limit for the servers as well. Any ideas?
