The short of it is, sort of. There are differences between the user-agent strings of the two if you really need to know. There’s was a lively discussion on this subject in the Internet Explorer forum last year where you can learn more: http://social.msdn.microsoft.com/Forums/en-US/iewebdevelopment/thread/7ecb58ca-1869-451b-920e-a27fed69a470. It’s also worth pointing out an old bit of documentation at http://msdn.microsoft.com/en-us/library/hh801221.aspx.

But it really boils down to feature detection, because the two browsers are meant to be interchangable.

    It’s a bummer though, that we cannot override ir extend the UserAgent string of xhr. That makes it difficult to detect and handle js app requests in the server. Have to introduce a custom X-App header for that. Any idea why the WinRt team decided to prohibit the change of the UA?

      I don’t know the reason there. I believe, though, that it’s a piece of feedback that they’ve heard from numerous places, so we’ll have to see if it’s improved in the next update.
