In the last chapter, “Introducing the Web Application Framework,” you learned about application variables, which live in your ColdFusion server's memory between page requests. You also learned that application variables are shared between all pages in your application. There are plenty of uses for application variables, but because they aren't maintained separately for each user, they don't go far in helping you create a personalized site experience.
