HTTP has been gradually adding lots of new and exotic headers, and more are on the way. Learn about current best practices with Vary, Link, Content-Security-Policy, Referrer-Policy, Client-Hints, Clear-Site-Data and Alt-Svc, upcoming features such as Feature-Policy and proposals like Variants, Early-Hints and Origin-Policy. HTTP gives you incredibly powerful control over many aspects of the way a browser will process the page, and is often a more effective or more secure option than trying to achieve the same effect with tags or script in the page.
