Upcoming Headers
| Cross-Origin-Embedder-Policy | Cross-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-Policy | Cross-Origin Opener Policy allows a site to opt-in to Cross-Origin Isolation in the browser. |
| Cross-Origin-Resource-Policy | Cross-Origin Resource Policy allows a resource owner to specify who can load the resource. |
Additional Information
| x-content-type-options | X-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-options | X-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-protection | X-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. |
| access-control-allow-origin | This is a very lax CORS policy. Such a policy should only be used on a public CDN. |
| referrer-policy | Referrer Policy is a new header that allows a site to control how much information the browser includes with navigations away from a document and should be set by all sites. |
| nel | Network 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. |
| public-key-pins-report-only | HTTP Public Key Pinning Report Only allows a host to test the effects of a HPKP policy before making it live. The browser will report on actions that would have been taken if the policy were live so a host can see what effect it would have. Analyse this policy in more detail. |
| expect-ct | Expect-CT will soon be deprecated and can be removed. |
| server | Server value has been changed. Typically you will see values like "Microsoft-IIS/8.0" or "nginx 1.7.2". |
| strict-transport-security | HTTP 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. |
