Question

I am trying to replicate the functionality of the page below where there are two tabs (Lady Gaga and Enrique Iglesias) which force users to like a page before they are able to use the app. With the latest Facebook changes is it still possible to be done? I am in the process of building my first app have been googling for the past week and have not gotten anywhere. I am literally pulling my hair :(. I hope somebody can help.
Thanks in advance,

The only way this can be done is by inspecting the signed_request http post parameter in server side code that Facebook sends your site when it loads your page. Here is an example of how to do it in PHP, although its basically the same process in whatever language you know.
