Hi, I am trying to get this work but I cant. Here is my configuration and tests: I compiled squid like this: ./configure --enable-auth-basic="basic" --enable-auth-ntlm"ntlm" --enable-external-acl-helpers="wbinfo_group" --enable-delay-pools Then I use this squid conf: cache_effective_user squid cache_effective_group squid cache_dir ufs /var/spool/squid/ 900 16 256 http_port 3128 coredump_dir /usr/local/squid/var/cache/squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 acl lan src 192.168.0.0/24 http_access allow lan visible_hostname SQUID-PROXY delay_pools 1 delay_class 1 3 delay_access 1 allow lan delay_access 1 deny all delay_parameters 1 1250/1250 -1/-1 1250/1250 Then, I try to download some file from Internet using this proxy and the speed doesn't change, I always download at max speed. Any idea? Really Thanks
