Glossary of Security Terms: HSTS

HTTP Strict Transport Security lets a web site inform the browser that it should never load the site using HTTP and should automatically convert all attempts to access the site using HTTP to HTTPS requests instead. It consists in one HTTP header,

Strict-Transport-Security

In other words, it tells the browser that changing the protocol from
HTTP to HTTPS in a URL  works (and is more secure) and asks the browser
to do it for every request.
