ACLs in HTTP

ACLs (Access Control Lists) in HTTP are security mechanisms that specify which users or systems can access certain web resources. Think of them as permission lists: they define who is allowed or denied entry to specific website content or functions, based on criteria like IP addresses, user roles, or request types. This helps websites protect sensitive information, reduce unauthorized access, and enhance security. By using ACLs, web administrators can control access carefully, ensuring that only authorized users can view or modify certain parts of a website or web application.
