Card 97 / 125: You are responsible for architecting an application for car agents. The application should save a lot of effort to its users. Instead of traversing about 30 commerce sites to check the new car offers, the application will collect these offers and render the list to the agent in one page. The agent will also be able to buy the car through this application directly. You expect a limited number of users to get access to the application. And for performance reasons you have to cache huge amount of data collected from the various commerce sites that must be maintained during the user session that spans the regular day working hours. What is recommended to use in this case to maintain the user session?
A) http session
B) stateful session bean
C) entity bean
D) stateless session bean
