Manipulating HTTP headers, specifically the User-Agent, can sometimes fool Cloudflare into thinking the request is coming from a legitimate browser. Setting the User-Agent to a common browser string (e.g., 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36') might bypass some basic checks, but it's not a reliable method.
