The helpers and their protocols are documented in the squid.conf notes. - url rewriters, url_rewrite_program - basic auth helpers, auth_param basic program - digest auth helpers, auth_param digest program - negotiate auth helpers, auth_param negotiate program - external acl helpers, external_acl_type Other helpers not so well documented outside source: - log daemon helper, logfile_daemon, access_log) - dns helper, ache_dns_program ((deprecated in favor for internal dns client) Regards Henrik
