hi list, I've been using tcp_outgoing_tos for a time now and i would like to make users (login) and url lookups against data store in a sql database. Im using something like: acl top_users proxy_auth "/etc/users.top" acl top_url url_regex "/etc/top_url" tcp_outgoing_tos 0x10 top_users tcp_outgoing_tos 0x04 top_url Is there a way to accomplish this? I've read that currently this feature doesn't support external acl lookups, is this true? regards, evelio vila VI Conferencia Internacional de Energía Renovable, Ahorro de Energía y Educación Energética 9 - 12 de Junio 2009, Palacio de las Convenciones ...Por una cultura energética sustentable www.ciercuba.com
