Upcoming Headers
Cross-Origin-Embedder-PolicyCross-Origin Embedder Policy allows a site to prevent assets being loaded that do not grant permission to load them via CORS or CORP.
Cross-Origin-Opener-PolicyCross-Origin Opener Policy allows a site to opt-in to Cross-Origin Isolation in the browser.
Cross-Origin-Resource-PolicyCross-Origin Resource Policy allows a resource owner to specify who can load the resource.
Additional Information
serverServer value has been changed. Typically you will see values like "Microsoft-IIS/8.0" or "nginx 1.7.2".
strict-transport-securityHTTP Strict Transport Security is an excellent feature to support on your site and strengthens your implementation of TLS by getting the User Agent to enforce the use of HTTPS.
x-content-type-optionsX-Content-Type-Options stops a browser from trying to MIME-sniff the content type and forces it to stick with the declared content-type. The only valid value for this header is "X-Content-Type-Options: nosniff".
x-frame-optionsX-Frame-Options tells the browser whether you want to allow your site to be framed or not. By preventing a browser from framing your site you can defend against attacks like clickjacking.
x-xss-protectionX-XSS-Protection sets the configuration for the XSS Auditor built into older browsers. The recommended value was "X-XSS-Protection: 1; mode=block" but you should now look at Content Security Policy instead.
