What are Cookies used for?
It is a convenient way for web sites to maintain information on users

Cookies and Browsers
Web Browsers (Netscape & IE) set aside a small amount of space on your hard drive
The Browser checks to see if you have any predefined preference (i.e cookie) for that server
If you do, it sends the cookie to the server along with the request for the web page

Suppose you visit http://www.joegarage.com Joe’s Garage uses cookiesYou type in your name and address and you
browse Joe’s page on all about oil changesNow, Joe knows that you are interested in oil
changes and he has your address so he sends you a coupon for a half-price oil change in mail

Cookies and Privacy
If you use Netscape you can tell when a web site is trying to “pull” a cookie on you
Under Netscape Edit Menu --> Preferences --> Advanced, a dialog window will appear with one indented box labeled cookies
