Using a PAC file is one method of securing internet traffic from AWS
WorkSpaces.
One method of securing internet traffic from Amazon WorkSpaces is by using a proxy
auto-configuration (PAC) file. A PAC file is JavaScript code that tells a web
browser how to connect to a proxy server. Enterprise environments employ PAC files
to control web traffic and enforce Security policy rules. A web server usually
stores the PAC file, and the web browser downloads the PAC file when it starts
up.
