Feature Cookies help a lot when you want to improve the quality of a user's visit. You can store information in a cookie that will let you deliver a better, more personalized experience the next time the visitor comes to your site. For example, if you offer two versions of your site, one with frames and one without, there's no need to make the user choose each time they visit. Instead, you can save their selection in a cookie, and then the next time they come to your door, your server can read the cookie and automatically deliver the preferred site type.
Cookies are especially useful in conjunction with dynamically generated pages.
If your site delivers information on a variety of subjects, you could use a cookie to store data about which topics the visitor has shown an interest in. Then, when the user returns to your site, you can generate dynamic pages that highlight those topics. For instance, a newspaper site might notice that a particular user invariably searches for basketball scores. The site could use that information to dynamically generate a custom page with a link to those scores right at the top. Inc. All rights reserved.
