Automatic Proxy

As an administrator, you most likely already use a proxy server with a firewall to create a barrier between your organization and the Internet, to cache frequently used content, and to balance server load. You can configure and maintain your proxy settings for computers running either Windows® 8 or Windows Server 2012 in the Internet Explorer Customization Wizard 10. For example, you can point your users' browsers to the location of your automatic proxy script.

Note

In an Active Directory environment managed with Group Policy, enabling the Administrative Templates policy setting Disable changing proxy settings locks proxy settings on your users' computers.

Proxy selection and proxy bypass lists

On the Proxy Settings page of the Internet Explorer Customization Wizard 10, you can enter addresses for the proxy servers that connect your users to the Internet.

Using automatic proxy

With automatic proxy, you can:

  • Dynamically configure proxy settings, such as server addresses.

  • Bypass proxy servers based on requests from the browsers on users' computers.

  • Modify proxy settings after deployment.

To enable automatic proxy, you create a separate .wpad, or .pac script file and then copy the file to a server location. Then, you configure the browsers to use the automatic proxy script file, by entering the script URL on the Automatic Browser Configuration page.

Note

If you specify a server location for an automatic proxy URL and an automatic configuration .ins file on the Automatic Browser Configuration page, the location of the automatic proxy script file is incorporated into the .ins file.

The automatic proxy script file is executed whenever Internet Explorer 10 makes a network request. Within the script, you can configure multiple proxy servers for each protocol type. If a proxy server connection fails, Internet Explorer 10 automatically attempts to connect to another proxy server that you have specified.

After deployment of your custom package, you can centrally maintain and update your proxy settings by modifying the script at the server location you specified on the Automatic Browser Configuration page.
