How do I configure Internet Explorer to use a PAC file?

To redirect your web traffic to the Zscaler cloud, you can configure your browser to use a Proxy Auto-Configuration (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 Geo-location technology to forward traffic to the nearest Zscaler Enforcement Node (ZEN).
