This tutorial starts with a brief explanation of the technical side of cookies, including how the browsers handle them and how cold fusion manages them. Then it shows you how to use cookies to track a user's progress through a website, using what the author refers to as a "cookie crumb" trail. This essentially adds a link for every page a user visits on a site, making navigation backwards easy as pie, while still allowing the developer some control over what pages the user is able to revisit.
