Summary
This website provides a platform for submitting domains to the HTTP Strict Transport Security (HSTS) preload list, which is a security feature that ensures browsers only access specified domains over HTTPS. It outlines the requirements for domains to be eligible for inclusion, including serving a valid HTTPS certificate, redirecting HTTP to HTTPS, and serving an HSTS header with specific directives. The site also offers guidance on the submission process and the implications of preloading HSTS for domain owners.
