Hi everybody, I am using: - squid 3.3.8 - c-icap 0.2.5 - My squid (icap related) configuration is as follows: icap_enable on icap_206_enable on icap_preview_enable on icap_preview_size 1024 icap_service_failure_limit 100 in 5 seconds icap_send_client_ip on icap_send_client_username on icap_client_username_encode off icap_client_username_header X-Authenticated-User icap_service web_acc_01 respmod_precache icap://192.168.1.65:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=100 icap_service web_acc_02 respmod_precache icap://192.168.1.47:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=10000 adaptation_service_set web_acc_set web_acc_01 web_acc_02 adaptation_access web_acc_set allow all I have couple of questions (problems) 1. THIS configuration works fine in situations where either .65 or .47 is not functioning ([down])- after 30sec or a valid OPTIONS call icap Service goes [up] and is in use again . BUT the same thing DOES NOT happen when the .65 server reaches his 100 max-conn limit. Squid does not go to .47 for adaptation. Squid does not try to call .47 later. On top of that if the "on-overload" is set to "block" client receives error page instead of modification from the .47 server. Did I make a configuration mistake or is something else wrong ? 2. Is there a way to do load balancing od 2+ server or to use the existing 2 servers with more efficiency ? 3. Is there a way to define a "double service" and do a load balancing with these phantom services as in this example icap_service web_acc_01 respmod_precache icap://192.168.1.65:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=100 icap_service web_acc_02 respmod_precache icap://192.168.1.47:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=100 icap_service web_acc_03 respmod_precache icap://192.168.1.65:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=1000 icap_service web_acc_04 respmod_precache icap://192.168.1.47:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=1000 icap_service web_acc_05 respmod_precache icap://192.168.1.65:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=10000 icap_service web_acc_06 respmod_precache icap://192.168.1.47:1344/echo bypass=1 routing=0 ipv6=off on-overload=bypass max-conn=10000 where the overflow of web_acc_01 will result in redirecting of requests at web_acc_02 then back to web_acc_03 which is a same physical but as a deferent virtual service with a different max-conn Thanks in advance G.Slavic
