Sessions
Companies keep track of what you do with either cookies or sessions. In your browser you can turn the cookies on or off. You may be able to also clear them out; sooner is better than later. Still, some companies intentionally write bad cookies that don’t expire or that hide on your system and continue to transmit data to them periodically.
The session is the same thing except you can’t see what is going on. The server will keep track of everything you are doing based on server scripts that you can’t see. Many people serious about your data will use sessions and also cookies.
If you go to a web page and click off of it, you might think that they aren’t looking at you anymore. However, the session stays connected unless you close down your browser. That means that if you browse for a few hours without closing your browser someone else can track all your surfing with a session you can’t see. If you want something secure, you need to search with a secure session. You can obtain a secure session by purchasing an IronKey, for mobile media, or through a good proxy server.
