Asking IIS to add X-Frame-Options crashes with a 500 Internal Server Error

For 'Default Website', I am trying to have the following feature. In Response Headers, trying to add the following headers

Name:  X-Frame-Options
Value: Allow From: http://matrimonial.lavanyadeepak.tld

The intent is have a script in http://www.lavanyadeepak.tld to access the iframe (with srchttp://matrimonial.lavanyadeepak.tld)

Any clues or examples? I am using the Windows Server 2012 (IIS 8)

 X-Frame-Options
