Hi, We do have three types of client proxy configurations at our company: 1. Direct proxy: proxy.company.com:8080 2. Auto-configuration file: http://proxy.company.com:8080/ 3. Auto detect proxy.company.com:80 Clients use ether one of the configuration. The client configuration can not be changed since we do have a lot of clients. I redesigned the proxy server since the old one could not handle the load anymore. The new server runs Squid. Configuration 1 and 3 work like a charm an I am very happy with it. My Question for you is: Is Squid capable of hosting the auto-configuration file? Or is there a workaround for that? Thanks, Jan
