Thanks to Phil for his info on IGear logins and PHP. I don't understand this yet - nothing new in that - but I'm not going to look into it until I've solved a more fundamental problem. This is hopefully something very simple - I've set up Squid so that if I dial out using wvdial and a modem, Squid can proxy/cache relevant internet files and clients can access them - so far so good. But if I connect through the city proxy using Netscape on the machine with Squid how does Squid find out where to get the Internet files. I can surf with Netscape on the Squid machine via the LEA proxy but I can't connect to a working version of Squid from the clients. I've searched through squid.conf without success. Obviously wvdial makes some sort of announcement which Squid detects and then uses. Any help appreciated. Dave
