 This feature is seamlessly integrated into Crawlee, requiring minimal extra setup. By default, requests are locked for the same duration as the timeout for processing requests in the crawler ([`requestHandlerTimeoutSecs`](https://crawlee.dev/api/next/basic-crawler/interface/BasicCrawlerOptions#requestHandlerTimeoutSecs)).
 If the Actor processing the request fails, the lock expires, and the request is processed again eventually. For more details, refer to the [Crawlee documentation](https://crawlee.dev/docs/next/experiments/experiments-request-locking).
 
-In the following example, we demonstrate how we can use locking mechanisms to avoid concurrent processing of the same request.
