MVC - First part

The Controller is the most important component because it handles all incoming requests.

DispatcherServlet(Front controller) --> HandlerMapping(URLs& ref control)--> Actual controller.

When the user sends a request, it first reaches the Controller.
The Controller layer typically includes:
1.Front Controller (e.g., DispatcherServlet in Spring)
2.URL Mapping (decides which controller method should handle the request)
3.Actual Controller Logic (processes the request and returns a response)
