Where do i place a java script i want run in header

[Vaupell]

I want to run this script, cause of problems with all pre ie8 versions.
got the code from http://msdn.microsoft.com/en-us/libr...12(VS.85).aspx

<![if lt IE 8]>
<meta http-equiv="Refresh" content="?styleid=2">
<![endif]>

and want to run it in header, so regardless which page the user enters,
they will always be checked, and then redirect to a style that works with
their brower..
