Deploying PAC Files

Deploying a PAC file explicitly using the browser proxy settings is one of the most straightforward methods for deployment.

Browser Deployment

Depending on the administrative environment, browsers can be configured automatically using a tool such as Group Policy, or manually for each browser’s connection settings.

Group Policy

The Group Policy settings will apply to Internet Explorer, Chrome, and Safari. Third party tools may be required for Firefox to adopt these Group Policy settings.

  1. Open the Group Policy Object Editor.
  2. Expand the User Configuration > Windows Settings > Internet Explorer Maintenance tree.
  3. Open Connection and select Automatic Browser Configuration.
  4. Check Enable Automatic Configuration.
  5. Enter the URL for the PAC file in the Auto-proxy URL text box, click OK.
