How to Block Iframe call

You can set the variable in the header X-Frame-Options: Deny.

All modern browsers support the X-Frame-Options header.

The Facebook uses this header to disable iframe/framesets (also Javascript).

If you have enabled the mod_headers in apache:

.htaccess

Header set X-Frame-Options DENY

But, you can enable iframes come from the same origin.

Header always append X-Frame-Options SAMEORIGIN

Or in Nginx:

add_header X-Frame-Options Deny; #or SAMEORIGIN
