Sniffing Browser History with NO Javascript!
http://www.making-the-web.com/misc/sites-you-visit/nojs/

Uses HTML and CSS to determine your browsing history. Slowish but effective.

This is a method of sniffing your browsing history without using Javascript. If you haven't cleaned your browsing history recently, just click "Start Scan" and the system will get to work.
