I would like to register a specific stylesheet for old IE browers within the page head (base-ie.css) like so :

<!--[if lt IE 9]><link rel="stylesheet" type="text/css" href="/ow_static/themes/the_theme/base-ie.css" media="all"><![endif]-->

What is the best way to do this? Should I develop a plugin? Which controller to extend?

Thank you.
