Do some work after a response has been sent to the browser

You can also use middleware to do some work after a response has been sent to the browser. Such middleware is called Terminable Middleware.

You can make a middleware terminable by defining a terminate method on a middleware.

This method will be automatically called after a response is sent to the browser. It will have both request and response as params.

class TerminatingMiddleware
{
    public function handle($request, Closure $next)
    {
        return $next($request);
    }
 
    public function terminate($request, $response)
    {
        // ...
    }
}
