What is a pac file and how do I open a pac file?
The configuration files mostly used by various web browsers for the selection of an appropriate proxy server are known as PAC files; which is why PAC files are also called Proxy Auto-Config Files. PAC files are categorized as web files because they contain JavaScript functions that are used in defining the rules needed to choose a proxy server based on the URL given. PAC files are very vital in corporate environments wherein websites are utilized for business processes as these files have the ability to control and load balance internet traffic that goes into a certain website. Web browsers enable PAC files when the PAC file URL found in the proxy connection settings is entered. These files can also be enabled by web browsers through the use of the Web Proxy Auto-Discovery (WPAD) protocol. A proxy.pac web server usually hosts PAC files and when these files are executed, a string containing numerous proxy server URLs is returned by the PAC file. PAC files can be edited with the use of a text editor because they contain JavaScript codes.
