About HSTS
HTTP Strict Transport Security (HSTS) is a web security policy mechanism that instructs browsers to only interact with a website using HTTPS, never HTTP. Defined in RFC 6797, it is implemented via a server response header that tells clients to enforce secure connections for a specified duration.
HSTS protects against protocol downgrade attacks and cookie hijacking by ensuring all communication is encrypted. It is widely adopted by security-conscious websites and is a key recommendation in modern web security best practices, supported by all major browsers.
