When compatibility view has been disabled in all ways possible it seems that Internet Explorer 11 on Windows 8.1 honours a website’s X-UA-Compatible
value†. This happens outside of compatibility view (the icon is missing from the address bar) and is not caused by compatibility lists or a <!DOCTYPE>
directive.
Is there any way for the user (not the web developer) to choose a document mode for a website, overriding the website’s X-UA-Compatible
value?
Force Internet Explorer 10 to open in non-compatibility view has accepted an answer that works by defining the default document mode with regard to the <!DOCTYPE>
directive. I've tried the registry trick without success. While it may have solved the problem for the other author’s question, my question has to do with X-UA-Compatibile
headers.
† Picasa Web Albums defines X-UA-Compatible
as IE=EmulateIE7
. Opening the F12 developer tools and switching document mode from 7 to anything newer (8, 9, 10, Edge) instantly fixes the website. However changes done through the developer tools do not persist.
Why not open it in Firefox or Chrome? They will always render as the latest browser – Ganesh R. – 2015-04-19T14:06:48.287
3@GaneshR. because average users do not want to juggle several browsers. I will always recommend they switch to a non-IE browser, but that doesn’t change my question about Internet Explorer’s document mode behaviour. – Martijn – 2015-04-19T14:25:13.770
Possible duplicate, yes, though IE11 was not displaying the compatibility view icon in the address bar in my case. Don’t know if there is a difference between the automatic document mode switch and the website requested one. – Martijn – 2015-04-19T17:11:42.700
As for the missing icon: any chance the site's URL has been added to intranet sites?

I have updated the question to (hopefully) explain why this issue is different from most compatibility mode related questions. Also hope this differentiates my question from the other one. – Martijn – 2015-04-21T10:03:10.453
