Sniffing Browser History Without Javascript

Ergasiophobia alerts us to a somewhat alarming technology demonstration, in which a Web site you visit generates a pretty good list of sites you have visited — without requiring JavaScript.

All it does is load a page (in a hidden iframe) which contains lots of links. If a link is visited, a background (which isn’t really a background) is loaded as defined in the CSS.
