188.8.131.52 Compatibility View
This functionality will not be implemented in any version of Microsoft Edge.
Compatibility View settings can also impact the document mode selection:
If a webpage is retrieved from a website in the Local intranet zone (see "About URL Security Zones" at [MSDN-SECZONES]), IE7 mode is used.
If the webpage is retrieved from a site in a domain on the Compatibility View list (and the list is active), IE7 mode is used (see "Understanding the Compatibility View List" at [MSDN-UnderstandingCompViewList]).
Compatibility View is controlled by browser settings. When a user clicks the Compatibility View button next to the Address bar in Windows Internet Explorer, the website is added to a local list of exceptions called the "Compatibility View list." The user can manage the list in the Compatibility View Settings dialog box.
The "Display all websites in Compatibility View" feature is not available in Internet Explorer 11.
In addition to the user's local Compatibility View list, Microsoft regularly publishes a list of popular sites that render better in Compatibility View. The user can choose to use this list by selecting the Include updated website lists from Microsoft check box in the Compatibility View Settings dialog box.
Finally, the user can choose to view all websites or intranet sites in Compatibility View by selecting the Display intranet sites in Compatibility View or Display all websites in Compatibility View check boxes in the Compatibility View Settings dialog box.
The following diagram shows how Internet Explorer determines the appropriate document mode based on Compatibility View settings.
