Auto proxy configuration settings for Internet Explorer 11

Configure and maintain your proxy settings, like pointing your users' browsers to your automatic proxy script, through the Internet Explorer Customization Wizard 11 running on either Windows 8.1 or Windows Server 2012 R2.

Updating your auto-proxy settings

You can use your Internet settings (.ins) files to set up your standard proxy settings. You can also specify script files (.js, .jvs, or .pac) to configure and maintain your advanced proxy settings. Internet Explorer uses your auto-proxy script files to dynamically determine whether to connect to a host or use a proxy server. If a proxy server connection fails, Internet Explorer 11 automatically attempts to connect to another proxy server that you have specified.

To update your settings

  1. Create a script file with your proxy information, copying it to a server location.

  2. Open the Internet Explorer Customization Wizard 11, and go to the Automatic Configuration page.

  3. Choose the Enable Automatic Configuration box to let you change the rest of the configuration options, including:

    • Automatically configure every box: Type how often Internet Explorer should check for configuration updates. Typing 0 (zero), or not putting in any number, means that updates only happen when the computer restarts.

    • Automatic Configuration URL (.INS file) box: Type the location of the .ins file you want to use for automatic configuration.

      For more information about setting up Automatic Configuration, see Auto configuration settings for Internet Explorer 11.

    • Automatic proxy URL (.JS, .JVS, or .PAC file) box: Type the location of your automatic proxy script. This script runs whenever Internet Explorer 11 makes a network request and can include multiple proxy servers for each protocol type.

      ImportantImportant
      Internet Explorer 11 no longer supports using file server locations with your proxy configuration (.pac) files. To keep using your .pac files, you have to keep them on a web server and reference them using a URL, like http://share/test.ins.

Locking your auto-proxy settings

You have two options to restrict your users' ability to override the automatic configuration settings, based on your environment.

  • Using Active Directory. Choose Disable changing proxy settings from the Administrative Templates setting.

  • Not Using Active Directory. Choose the Prevent changing proxy settings setting in the User Configuration\Administrative Templates\Windows Components\Internet Explorer Group Policy object. For more information about Group Policy, see the Group Policy TechCenter.
