To my knowledge, there isn't one. Anandtech uses DailyTech as a news feed for their main site. The two technically aren't affiliated in any way that I know other than a bond of pure friendship between Anand and Kris (insert "aww" here

).
EDIT:
It's possible that maybe they could add a referrer tag to their URLs that if a proper site name is given (such as dailytech.com/article.php?id=453&referrer=Anandtech) it would know to put something on the top of the page that said "Return to Anandtech". By using a known referrer system, it eliminates the possibility of referring malicious URLs.
