Definition: The word "use_rbl_domains" refers to a web-based framework or platform that allows developers to control access to their website's hosting space, specifically domains (like .com or .org) without having to manually do it themselves. This helps in managing security and privacy concerns in web applications. Detailed definition: To use RBL (Real-World Binding Library), developers can customize a web applicationβs domain mapping to allow different browsers to access the site while ensuring security by automatically providing the necessary HTTP headers, such as "Strict Transport Security" or "Cross-Origin Resource Sharing." This approach streamlines user experience and compliance standards.
