What is the purpose of a robots.txt file and how does Cloudflare manage it?

A robots.txt file is a text file placed in the root of a website to instruct web robots (crawlers) which parts of the site they are allowed to crawl and which parts they should avoid. Cloudflare allows you to manage your robots.txt file through its firewall rules, providing a convenient way to control access to your website while benefiting from Cloudflare's security features. You can define rules to disallow access to specific directories, file types, or even entire IP ranges.
