What is CSRF protection in Laravel?
Resposta
CSRF (Cross-Site Request Forgery) protection prevents cross-site request attacks by validating a unique token for each session. Laravel automatically generates this token and verifies it on all POST, PUT, PATCH, DELETE requests. API routes are exempted as they typically use stateless token-based authentication.
