X-UA-Compatible for IE users

s I understand by default, all internet sites display in IE8 Standards Mode (Compatibility View off) while all intranet sites display in IE7 Standards Mode (Compatibility View on).

If I set META TAG as

<meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE8″ />

it will work IE without checkbox and it will be Compatibility View off.

Is this correct solution or there is better solution than this?

We have current version at URL:
[URL=”http://windows.microsoft.com/en-US/internet-explorer/downloads/ie”]http://windows.microsoft.com/en-US/internet-explorer/downloads/ie[/URL]

IE v9-7.

So, issue is v7 or IE9 has the same setting as v8 (Compatibility View off)?
Can be solved with PHP script to detect IE version and control this?
