As you travel around the internet, you leave a trail to follow. When Hansel and Gretel walked through the forest, they left a trail of crumbs. Your four-year old also leaves a trail of crumbs - especially after eating crackers.

Thus the term cookie - refering to a group of crumbs - came into common usage.

A cookie is used by website author's to remember you when you come back. This is so that you can get the greeting: hello spaz. You last visited our page 01/09/04. Since then there has been 4 new articles posted. etc etc.
