Configuring Safari to Use PAC File

Configuring Safari to Use 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).

To learn more, see How do I use default PAC files to forward traffic to the Zscaler service?

The following steps describe how to configure Safari to use a PAC file. The browser version used in this example is Safari 11.0.1 (13604.3.5).

To view the default PAC file:
