The X-Frame-Options
HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a <frame>
, <iframe>
, <embed>
or <object>
. Sites can use this to avoid click-jacking attacks, by ensuring that their content is not embedded into other sites.
The added security is provided only if the user accessing the document is using a browser that supports X-Frame-Options
.
Note: The Content-Security-Policy
HTTP header has a frame-ancestors
directive which obsoletes this header for supporting browsers.
Header type | Response header |
