Igor, Hi Thanks for your reply. Yes, I was talking about the peer option in HAProxy; but I think that option is appropriate in a situation that the two load balancers are configured to use the sticky table as the mechanism to maintain active sessions; is that right? In other words, if the cookie method is used, there is no need to synchronize the sticky table between two load balancers; do you agree? Now, is the same situation valid for Apache? I mean, if we configure two apache servers using mod_proxy_balancer as load balancers and also configure the back-end web server to set the cookie, in a case when one of the load balancers fails, is the session maintained using the other active balancer? By the way, suppose that there is only one back-end web server. Thanks again.
