On the site, it says that Ghostery detects trackers by parsing the HTML on a page. However, I can't seem to find the trackers if I were to look through the source code of a page itself. For example, on CNN.com, Ghostery detects multiple trackers including Krux Digital with a URL of http://cdn.krxd.net/controltag.
I cannot find this URL myself in the source code of the site. How exactly does it work?

1It's recursive. Locate the line that looks like
<script src="http://z.cdn.turner.com/cnn/tmpl_asset/static/www_homepage/2928/js/hplib-min.js"></script>
and examine that script's source — you'll find Krux Digital there. -
