<meta http-equiv="X-UA-Compatible" content="IE=edge" />
        <meta http-equiv="X-UA-Compatible" content="IE=10" />
Both of these lines of code exists in this header of aspx file.  I know "Edge" renders the most recent version of IE.  What's the meaning of the 2nd line of statement to render it in IE version 10?    Does it have any impact?

Thank you.

It is to force IE10 mode but you can't have both in the same file, the first one should take precedence

If the "first one" takes precedence, so does that mean it will always render in the latest IE version?

And the loc " <meta http-equiv="X-UA-Compatible" content="IE=10" />" is just ignored?

By rights it should as that tag should be the first declared meta tag in the head. Any other tags before it should cancel the compatibility (according to MS)

Gary, I'm sorry but I'm not clear at all with your answer.
Which LOC exactly will be use and which will be ignore?  Latest IE or IE10?  Thanks.

Which one do you want to use?
By all accounts you should be forcing the latest version

<meta http-equiv="X-UA-Compatible" content="IE=edge" />
