HSTS
Abbreviation for HTTP Strict Transport Security
In short and in plain language
HSTS is a setting on a web server.
With it, a site tells the browser how to open it. From then on, it should only use encrypted links.
This makes it harder to catch or redirect links.
When the site moves to a new server, this should go on without a break.
Definition
HSTS is a web server setting that tells the browser to open the website only over an encrypted connection from then on. This makes intercepting or redirecting connections harder. When moving to a new server, encrypted access should therefore continue without interruption.
