What is a PAC File Type?

PAC files are enabled in web browsers by entering the URL of the PAC file into the proxy connection settings, or by using the Proxy Auto Web protocol-Discovery (WPAD) protocol. When executed, a PAC file returns a string containing one or more proxy server URLs. The PAC files are usually hosted on a web server and named proxy.pac.S since the PAC files contain plain text. You can use a text editor such as Microsoft Notepad or Apple TextEdit to modify or view files.NOTE: The PAC file format was originally released in 1996 for use by Netscape Navigator 2.0.
