I would like to understand how the facebook comment plugin, that is inserted inside a web page, using a javascript script and a div tag, works.
If I try to guess (and using firebug), the javascript part loads an iframe that is inserted inside the div part.
My problem, is that everybody can put a comment feed that is not necessarily ralative to the web page content! Suggest I’m example.com, how can I be sure that example.org is not using my example.com facebook comments?
Does Disqus works similarily?
Thanks in advance.
The facebook url that is loaded within the IFRAME has access to the
REFERRERURL (which is the loading page in this case) and uses it to check the domain.
