What is a PAC file?
When browsing the internet, it uses a javascript called Proxy Auto-Configuration (PAC) file. The file aids in determining whether the browser should go direct or redirect to a web proxy server via the Find ProxyURL function. Typically, they help balance heavy web traffic, especially in busy companies by deciding how many days in a week and time of the day traffic goes to a proxy. You also get to choose which sites not to proxy while maintaining privacy. One advantage is that it is not hard to create and maintain proxy files. Other pros include support by most popular browsers and the ability to support mobile browsing even the most standard. The browser needs only the specific address of the .pac file to execute javascript.
To activate PAC files, you need to paste the required URL in the proxy connection settings or use the WPAD protocol. Once active, you will get a string of suggested URLs. Lastly, Pac files are hosted on web browsers under the name proxy.pac.
