While directly they are as inocious as you have noted, they can (and have) been used for much more then simple data storage. The method is rather simple (and proven). A company such as doubleclick.com contracts with many sites for advertising. When you visit the site it includes html to grab the banner from doubleclick.com's servers. The particular html code identifies where you currently are. The doubleclick.com drops a cookie that is then related to the visit. Now you go to another site with ads. And again your browser converses with doubleclick.com. This time the cookie is sent back to the company servers. And guess what? They remember who you are. They loged your IP address and where you were last. Now the upfront explaination (and it would be fine if this were the only thing done) is that they want to send you the most effective advertising they can. They don't want to send "midol" ads to an all guy dorm. They would rather advertise power tools. (Bear with the me on the generalization.) But they have admitted that it goes a little further. They discovered that some companies will pay money for the data of where you visited. They can detirmine what your habits are and what ISP(s) you use. (That nasty IP address with reverse DNS is a killer.) They know which ads you have clicked on. Now if I believed it would stop at their desire to sell me a better saw all would be fine. But invasion of privacy never has stopped at marketing. Next, it is used by the police. (Yes, some countries care where you go.) Perhaps you may find one day you are being observed by the FBI. While I sound like a paranoid freak, it has happened. Not too many years ago it leaked out that the FBI has files on many fine citizens from the communist witch hunt of the 60s. I will deal with my black helicopters, but when you find you are under investigation for being a subversive person don't say you weren't warned. ======= Kirk Wood Cpt.Kirk at 1tree.net Nothing is hard if you know the answer or are used to doing it.
