Configuring Google Chrome to Use a PAC File

To redirect your web traffic to the Zscaler cloud, you can configure your browser to use a PAC file. A PAC file is a text file that directs a browser to forward traffic to a proxy server before going to the destination server. The Zscaler service hosts a default PAC file that uses geolocation technology to forward traffic to the nearest ZIA Public Service Edge.
