This chapter has shown you how to use application and session variables, along with other useful features such as Cache objects and cookies. These features will allow your applications to maintain a certain amount of state, both for the user and session, in the application itself.
This chapter has also given you a useful application that you can use in many of your Web sites. Many times, users enjoy posting items they want to sell, or looking through items they might want to buy. I would like to see what you can do with this application, so if you use it and modify it, please send me an e-mail so that I can see what you have done.
