X-Frame-Options¶
The X-Frame-Options HTTP response header defends an application from clickjacking attacks. It can be used to indicate whethera browser is allowed to render a page in a frame, iframe, embed or object.
For example, to disallow displaying of a page in a frame:
X-Frame-Options: DENY
This header can be configured in three ways:
DENY– disables the iframe features completely.SAMEORIGIN– allows iframe to be used by anyone from the same origin.ALLOW-FROM– allows iframes from specific URLs
Nginx¶
Add the following parameter to the nginx configuration file in the server section:
add_header X-Frame-Options "SAMEORIGIN";
Apache¶
Header always set X-Frame-Options "SAMEORIGIN"
