Typoscript to include IE specific css and js

Here is how we can include css and javascript that targets different Internet explorer versions using typoscript.

page {
includeJS {
iejs = fileadmin/templates/js/ie.js
iejs.allWrap = <!–[if lt IE 9]> | <![endif]–>
iejs.excludeFromConcatenation = 1
}

includeCSS {
iecss = fileadmin/templates/css/ie.css
iecss.allWrap = <!–[if lt IE 9]> | <![endif]–>
iecss.excludeFromConcatenation = 1
}
}

Here I am including css and js for ie version less than 9.
