Sniffing Browser History Without Javascript 216

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. NoScript will not protect you here. The only obvious drawbacks to this method are that it puts a load on your browser, and that it requires a list of Web sites to check against. "It actually works pretty simply — it is simpler than the JavaScript implementation. 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. The 'background' image will log the information, and then store it (and, in this case, it is displayed to you)."
