A PAC file works by defining a set of rules that determine whether a request should be sent directly to the destination server or forwarded through a proxy server. The e1207y PAC file contains JavaScript code that is executed by the browser or application, which then determines the proxy server to use based on the rules defined in the file.
function FindProxyForURL(url, host) { if (shExpMatch(host, "*.example.com")) { return "PROXY proxy.example.com:8080"; } else { return "DIRECT"; } } In this example, the PAC file checks if the host matches the pattern "*.example.com".
