The earliest Web sites were collections of independent, mostly static HTML pages joined together only by links. These sites offered little in the way of interactivity and did not profile users to customize their experience as is now commonplace.
ASP has many features that you can use to add customization to a user's visit and to your Web site, and we'll cover them in this module.
By the end of this module, you will be able to:

1. Explain why the lack of "state" on the Web causes difficulty in retaining user data
2. Explain how the Session object and session variables maintain user information throughout a site visit
3. Describe and create a Global.asa file with common user start and end procedures
4. Display a banner image or text that rotates through a series with the Advertisement Rotator component
5. Explain how the Server object can URL encode data that includes a space or other character not allowed inside a URL
