如果我为 squid 配置了多个传出 IP 地址并使用 user:pass auth，我如何让用户只访问特定范围的地址？
目前我只是像这样进行身份验证...
auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/squid_passwd
auth_param basic children 5
auth_param basic realm Proxy Auth Required
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off
acl ncsa_users proxy_auth REQUIRED
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow ncsa_users
http_access deny all
