Based on a link I have found (can't post it here due to the forum software) there is apparently a way to show a special purpose page displaying:
"
This website needs Internet Explorer This website uses technology that will work best in Internet Explorer.
Open with Internet Explorer
Keep going in Microsoft Edge
"
It will be very helpful for my applications using Active X controls. I have already code such as
<meta http-equiv="X-UA-Compatible" content="IE=10;requiresActiveX=true" />
in my head section (added in the past to avoid Metro style for Win 8), but it doesn't do the trick (unlike someone mentioned at the link above).
I'll be glad to learn about the proper code to add to achieve this.
