Description: The Application Controller is the base controller from which all other controllers in a web application inherit. In many web frameworks, this controller acts as a central point for managing the application’s requests and responses. Its primary function is to facilitate communication between the model and the view, ensuring that data is processed correctly and presented appropriately to the user. As the parent class of all controllers, the Application Controller allows for the implementation of methods and filters that can be used in all derived controllers, thus promoting code reuse and consistency in application logic. Additionally, it is common to define authentication and authorization methods in this controller, which reinforces the application’s security. In summary, the Application Controller is fundamental to the structure and functioning of a web application, as it establishes the foundations upon which user interactions with the system are built.
