📋 Note: This is an example service that generates proxy auto-configuration (PAC) files for Microsoft Entra Internet Access and is intended for testing/validating explicit forward proxy features. Please do not use this service for broad production deployments. This service is not supported by Microsoft and may be decommissioned without notice. Open source files for this service are available on GitHub.

Usage

This service hosts customized PAC (Proxy Auto-Configuration) files for Microsoft Entra Internet Access. Each PAC file is dynamically generated based on your tenant ID.

PAC File URL Format

https://pac.azureidentity.us/YOUR_TENANT_ID

Example

If your tenant ID is 12345678-1234-1234-1234-123456789012, your PAC file URL would be:

https://pac.azureidentity.us/12345678-1234-1234-1234-123456789012

Note: Both HTTP and HTTPS are supported, but HTTPS is recommended for security.
