I got code when I navigate to stc/siteviews/layout.css. Is there a better one I should test with?

As I look at the page source, though, I see this, which struck me as strange:

{link rel="stylesheet" href="http://cssproxy.$DOMAIN/?u=http://$DOMAIN_WEB/users/system/res/0/stylesheet%3F1340407627" type="text/css" /}

($VARS are subbed for my domain)

The syntax of that code just looks... odd to me.
