Front Controller


Using a single component to process application requests.

Where to use & benefits


Design a servlet to deal with all the requests. The logon page is the first request. When the logon is allowed, the controller will present contents to the user. If the user has further request by clicking a link or a button, such request will be sent to the controller and the controller will decide if such request is granted or not, if so, the next page will be presented to the user, and so on.
