Help with: IE conditional comments in header for modular css.

Hello,

I have been working on my new site using wordpress as the frame work. I know some PHP. I understand some, but cannot code myself. What I am trying to do is set this in my header:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen, projection" />
<!--[if lt IE 7]>
<link type="text/css" rel="stylesheet" href="win.css" media="screen, projection" />
<![endif]-->

That way I can have a separate style sheet for ie css rules.

• As you can see, a relative link will not do and an absolute link will not do.

I looked inside the theme.php file within wp-includes. Assuming that I may be able to customize something inside there but I have had no luck.
Does anyone have any idea how I could accomplish this in wordpress?

Thanks in Advance.
