On our site we currently have approx. 50% of our IE7 users running Windows 7. However, Win7 was released with IE8 meaning that something is not right. Based on this, we made the assumption that the modern IE browsers enter IE7 compatibility mode on our site. So we placed the "X-UA-Compatible=edge" meta tag on our site in hope to kill off IE7 support. However, after a week, the percentage of IE7 (and IE8) users have gone up for the first time since the start of this year. When looking at the X-UA-Compatible documentation, it is meant to be used for putting your site into an older mode.
- Is there any other way to make sure that IE doesn't enter compatibility mode?
- Is there something else we need to look for?
And yes, we have so many users on our site that we can't kill off IE7 until it goes down under 2% of unique visitors.
EDIT: We use <!doctype html>
EDIT2: We haven't been able to reproduce the compatibility mode in our environments either
