title: Allow others to iframe my site
body: <p>If others tries to iframe my site they get error "Refused to display in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'
  ". Do they have to change something, or I, or both?
  I found there are options for X-Frame-Options :SAMEORIGIN,DENY,and allow only one site. Configuration :IIS8, ASP.NET MVC. Are there any global settings to allow others to iframe my site?</p>
