What is Middleware Kernel?

English: In Laravel, middleware are filters that run before or after a request hits your application. The Kernel is the place where Laravel manages these middleware. It is like a traffic controller.

🔸 Hindi: Laravel में middleware वो filters होते हैं जो किसी request के आने से पहले या response भेजने से पहले चलते हैं। Middleware Kernel वह जगह है जहाँ Laravel यह तय करता है कि कौन-कौन से middleware कब और कहाँ चलेंगे।

✅ Real-World Example (Simple Use Case):

Imagine you’re building a school management system.

• You want every route to check for maintenance mode → use global middleware
• Your web routes need session and CSRF protection → use web group in middleware kernel
• Your API routes should be rate-limited → use api group
• A route like /admin should be accessible only if the user is admin → use route middleware like admin
