Else, the rest should be identical with the original example file that was included in install package. squid seems to start normal. when opening a browser, the user are asked for user/pass. Is data ok, the user sit in a sandbox - or session. Ok, so far. Now, I want to call a external helper. But it is not execute. I don't know why. I have set the permissions of files to user/perm: squid:squid / 755 And, the config and logs are on different locations, not the default system, to avoid overhead productive hard disk system. My system is Debian Jessie 8.2 Here is the script: http://pastebin.com/yh6LHG1k Please help, I am lost _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
