Summary

Every Web application is different, but you should now have the information you need to create a secure and efficient mechanism for maintaining session in any programming language. The techniques introduced in this chapter should become intuitive as your understanding of HTTP strengthens.

The most important point to remember in these past three chapters is that you should take the time to consider the most appropriate technique for maintaining state and session prior to implementing anything. Rather than just “switching on” session management in your Web scripting language of choice and adding things as you go, take the time to carefully consider the information you need to maintain per user and the characteristics of each element in the design phase. This simple step can allow you to make better decisions about the techniques you employ as well as save you from possible frustrations during development.
