What is an App Profile PAC file used for?

Comprehensive and Detailed 100 to 150 words of Explanation From Zscaler Digital Transformation Administrator topics:

An App Profile proxy auto-configuration (PAC) file supplies traffic-handling logic to Zscaler Client Connector, making C correct. Its JavaScript rules determine whether applicable traffic should be sent to the Zscaler service, forwarded to a designated proxy, or bypassed and sent directly. Zscaler documentation explains that Client Connector can use the App Profile PAC file to select the appropriate Zscaler data center and apply URL, domain, or address-based forwarding decisions. A PAC file does not encapsulate traffic in GRE; GRE is a separate location-forwarding mechanism. It also does not independently establish TLS sessions or classify sensitive data, which are handled by tunneling and data-protection capabilities respectively. Therefore, the PAC file’s operational purpose is to guide Client Connector traffic forwarding.
