Introduction

HTTP is a stateless protocol. This means that each request is handled independently of all the other requests and it means that a server or a script cannot remember if a user has been there before. However, knowing if a user has been there before is often required and therefore something known as cookies and sessions have been implemented in order to cope with that problem.

On page two we will look at cookies and sessions will be covered on page three. On page four we will talk a bit about security.
