Hi all.. Is it possible that whenever a user makes a request to squid server for http browsing, a program gets fired checking some conditions applied on the user and if condition is met then only allow the user to browse. If it possible then how .... If anyone know then please tell me. Regards Imtiyaz ---------------------------------------------------------- Netcore Solutions Pvt. Ltd.
