Hello! I would like to create 2 accounts per each proxy user(IP address): one limited and one unlimited i tried this way : ... auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/passwd auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 192.168.0.0/255.255.0.0 acl to_localhost dst 127.0.0.0/8 acl password proxy_auth REQUIRED icp_access allow all always_direct allow all coredump_dir /var/log/squid/ ######################### acl limited proxy_auth l1 l2 acl unlimited proxy_auth u1 u2 ########################## delay_pools 1 # limited delay_class 1 2 delay_parameters 1 15000/15000 1875/1875 delay_access 1 allow limited delay_access 1 deny all #unlimited http_access allow unlimited http_access allow limited http_access deny manager http_access deny all http_reply_access allow all ..... the problem: when i connect to proxy as user l1(limited by 1875B/s) all OK but when i create additional connection as user u1(unlimited) from the same IP adress bad things happen. connection belonging to l1 gets 7.5KB/s (but is should be limited to 1875B/s)! Can you help me overcome such problem? Thanks!
