It's amazing what can be tracked with cookies, including across sites. There was an article, in The Australian I think, a few years ago describing information PBL had accumulated through cookies. How many times do you go to a website and get cookie requests from several? How hard would it be to match cookies across domains? Information readily available to seach site supplying a document includes referrer, client IP address, time. Say I go to http://www.example.com/ which sets a cookie and includes a document from http://tracker.example.com/, and passes the cookie data (or a token identifying it so as to hide what's going on), and tracker also sets a cookie. Then I go to http://shop.example.com/ and it includes a document from http://tracker.example.com. Cannot tracker match my two visits, and maybe record my credit card detaisl "for my greater convenience>" I tend to allow session cookies, but rarely permanent cookies. I also tend to use divers browsers and computers which surely must help confuse things. -- Cheers John Summerfield -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
