What are cookies, and do they pose me any risk?
A cookie (also called a Persistent Client Side State Object) is a little piece of information handed to a WWW client by a WWW server, containing information that can be retrieved by the server later. For instance, a server can hand your browser a cookie when you fill out a form stating your preferences for visiting that server. Then, the next time you visit the site, the server can read your preferences from the cookie and customize the appearance of the Web site to your preferences.
