PAC File
A PAC (Proxy Auto-Configuration) file is a text file that instructs the browser to forward traffic through a proxy server.
By distributing and configuring it on user devices, end users can start using the proxy without any special actions, while administrators can enforce flexible access control.
By default, PromoProxy provides a pre-configured PAC file.
The default PAC file already includes the necessary settings to use PromoProxy, allowing you to begin using the service immediately with minimal setup effort.
PAC files are written in JavaScript, enabling fine-grained control using conditional logic. For example, you can configure rules such as:
- Always route traffic through the proxy for specific domains
- Bypass the proxy and connect directly for internal network destinations
- Switch connection routes depending on the user’s IP address or network environment
By leveraging PAC files, you can build a flexible network configuration that ensures both security and convenience.
For details on PAC file setup, please refer to the Quick Start.
In the Free Plan, only the default PAC file is available.
