TrailScout is a cookie-based PHP script that displays a path of hyperlinks to previously visited pages on a Web site. For example "Vacilando.Net > Writing > PHP Scripts > TrailScout". It is also known as a "cookie crumb trail". The path is stored in a cookie for the duration of one session (i.e. until the user closes all browser windows). For each new visited page, the title and the URL are stored in the session variable. If the user visits a page that has been seen before, the trail of links is reduced and that page again becomes the last one. The number of links stored in the trail can be limited.
