In squid.conf configuring: acl haproxy src x.x.x.x # HAProxy Load Balancer IP follow_x_forwarded_for allow haproxy In haproxy.cfg configuring: defaults global log mode http option httplog option dontlognull timeout connect 5000 timeout client 50000 timeout server 50000 errorfile 400 /etc/haproxy/errors/400.http errorfile 403 /etc/haproxy/errors/403.http errorfile 408 /etc/haproxy/errors/408.http errorfile 500 /etc/haproxy/errors/500.http errorfile 502 /etc/haproxy/errors/502.http errorfile 503 /etc/haproxy/errors/503.http errorfile 504 /etc/haproxy/errors/504.http frontend squid bind *:3128 default_backend squid_pool backend squid_pool mode http SERVERID cookie insert indirect nocache balance source hash-type consistent option httpclose option forwardfor header X-Client option forwardfor server px1 x.x.x.1:3128 check inter 2000 rise 2 fall 3 server px2 x.x.x.2:3128 check inter 2000 rise 2 fall 3 Greetings!
