Hello Willy, I have worked about this issue and find out some interesting things about what was going on. You put me on the right way, thanks for that. In fact, my application is sending HTTP requests to many web servers (at least 6). Since the same cookie name was used in HAPROXY for all servers, the cookie value was set according to server to which HTTP requests was sent. this explain why affinity between my browser and serv_1 or serv_2 was broken. I have updated cookie name for each pair of servers (serv_1 & serv_2 have the same fonction, Serv_3 et Serv_4 also and so on...). Now when setting cookies to check a specific server, all HTTP requests are sent to the desired server. Thank you very much for your help.

Behind this reverse proxy, there are 2 web servers (Serv_1 & Serv_2). If I stopped Serv_1, all HTTP requests from my browser are sent to Serv_2 even if cookie serv1_cookie is set and CHECK_FRONTEND is equal to true in my browser. Since I used force_persist option in HAProxy, my HTTP requests should be routed to Serv_1. I don't understand what"s going on.
