You can have centralized control over Enterprise Mode by creating a single, global XML site list that includes the list of websites to render using Enterprise Mode. You can add and remove sites from your XML list as frequently as you want, changing which sites should render in Enterprise Mode for your employees. For information about turning on Enterprise Mode and using site lists, see Turn on Enterprise Mode and use a site list.

How Internet Explorer 11 looks for an updated site list

  1. Internet Explorer starts up and looks for an updated site list in the following places:

    1. In the cache container. IE first checks the cache container to see if it finds your XML site list.

    2. In the local cache. If there’s nothing in the cache container, IE checks your local cache for the site list.

    3. On the server. Based on standard IE caching rules, IE might look for a copy of your site list in the location you put specified in the SiteList value of the registry.

  2. If there’s an .xml file in the cache container, IE waits 65 seconds and then checks the local cache for a newer version of the file from the server, based on standard caching rules. If the server file has a different version number than the version in the cache container, the server file is used and stored in the cache container.

    If you’re already using a site list, enterprise mode continues to work during the 65 second wait; it just uses your existing site list instead of your new one.
