In this chapter, we covered several methods that you can integrate into your servlets to handle persistent sessions. We talked about the hidden form fields, persistent cookies, URL rewriting, and the Servlet API's built-in session handling support. At this point, you should be able to examine your session handling requirements and determine which method satisfies your needs. You should also be able to implement a session handling solution based on your decision.
In the next chapter, we will look at communication between Java applets and servlets using a method call HTTP tunneling.
