The **Front Controller** is a pattern that centralizes the handling of all requests coming into a web application through a single object (usually a Servlet or an `index.php` class).

Instead of having each HTML or PHP page handle its own security and routing logic, the Front Controller receives the request, performs common tasks (authentication, logging, internationalization), and then delegates the execution to the specific command or controller.

# Advantages of Centralizing

• router

  Dynamic Routing

  Allows changing the URL structure without moving physical files.

• security

  Central Security

  A single place to check if the user has permissions.
