So I've noticed that google adsense keeps track of what links clicked on your site.
For example, assume MySite.com uses adsense AND website MyBlog.com links to MySite.com from file MySite.com/files/path/helloworld.html AdSense will actually provide you the full link.
Does anyone know how they do this? In know you can use the http "host" header in your code. But that just provides MySite.com not the full path.
