Laravel 11 introduces per-second rate limiting for API throttling, providing more precise control over request rates.The per-second rate limiting feature is beneficial for APIs that require stricter throttling policies to prevent abuse and ensure fair usage.Implementing per-second rate limiting in Laravel 11 is straightforward by using the throttle middleware in the routes file.For more complex rate limiting logic, developers can define a custom rate limiter in the boot method of the RouteServiceProvider.
