Proxy auto config (PAC) file parser systems and methods

Abstract:

Proxy Auto Config (PAC) file parser systems and methods enable file parsing on user devices without Just-in-Time (JIT) compilation in JavaScript, with a memory efficient implementation and with efficient performance. The PAC parser supports multi proxy connections, traffic rules (e.g., bypass/send to proxy, etc.) based on various PAC functions, etc. The PAC parser can be utilized on a user device with an enterprise application and with cloud-based services.
