+### handle Headers already sent
+
+Since 2.13.0, we can handle header already sent by pass callable via `Response::setHeadersSentHandler()`:
+
+```php
+use Laminas\Http\Response;
+
+$response = new Response();
+$response->setHeadersSentHandler(function ($response): void {
+    throw new RuntimeException('Cannot send headers, headers already sent');
+});
+```
