Additional Information
nelNetwork Error Logging is a new header that instructs the browser to send reports during various network or application errors. You can sign up for a free account on Report URI to collect these reports.
report-toReport-To enables the Reporting API. This allows a website to collect reports from the browser about various errors that may occur. You can sign up for a free account on Report URI to collect these reports.
serverServer value has been changed. Typically you will see values like "Microsoft-IIS/8.0" or "nginx 1.7.2".
set-cookieThere is no Cookie Prefix on this cookie. This is not a SameSite Cookie.
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.
