Hello to everyone, First of all thanks for the support and for this awesome product. I'm developing a captive portal with squid 3.4.9 over ubuntu 14.04 Here is my external acl configuration external_acl_type session_active_def ipv4 %SRC /etc/squid3/captive/sessionHelper.php concurrency=100 children=1 -a -f ttl=1 negative_ttl=0 startup=2 idle=1 acl password external session_active_def deny_info https://proxy-bump.upr.edu.cu/?url=%u password And the captive portal autenticate users against Active directory and save authorization data to memcache server on the same proxy server. External acl sessionHelper.php checks for those authorization data in the memcached server. I have not authentication, only authorization by ip using that external acl and returning autenticated user so squid log the username information. Everything works like a charm except for the frequency squid checks for those authorization data in the external acl, I has tried every configuration sample found in the internet but without success, ttl parameter of external acl doesnt works for me. Session login and logout doesn't work as expected due to squid doesn't check this external acl frecuently enough, user can surf after closed session (removed user authorization data from memcache server) because squid doesn't authorize anymore same ip requests using the external acl. Only way I found to force squid to check for the acl was reloading configuration like /usr/sbin/squid3 -k reconfigure But this gives me lot of instability because squid stop accepting connections for the time it is reloading configuration, I have lot of people opening and closing sessions so right now squid is reloading each minute to cover that demand. My question: is there a way to force squid to check the external acl each 1 second or just for every request without reloading configuration. I've tried all for over a month and you are my last resort, please help, and forgive my english also.
