I want to restrict my site content to be used in other domains through iframe control. The recommented meta tag i.e <meta http-equiv="X-Frame-Options" content="deny">
is not working. What can i do?
You can't set X-Frame-Options in a metatag, only using the HTTP header.

For example, if you are using Apache, you should add a line like this in the .htaccess file
Header set X-Frame-Options DENY
