Proxy Auto-Configuration (PAC)

A Proxy Auto-Configuration (PAC) file is a script used by web browsers to automatically determine whether your internet traffic should go directly to a website or through a proxy server. The PAC file contains rules that tell the browser which connection to use for each request, helping to optimize speed, enhance security, and manage network access efficiently. Essentially, it automates the decision-making process for routing your internet traffic, ensuring the right connection is chosen based on predefined conditions without requiring manual configuration for each website or network situation.
