How to check whether the user likes this page on facebook from an external site?

Question

I am creating an application using facebook like under GAE with python.

I would like to do different things if the user liked the page or not:

page_url=url
if user likes page_url:
   #do something
else:
    #do something else

I am interested in checking if the user likes this page, and not by pressing a button of a similar type.

I would also like to do this without requiring a facebook connection.

Thank!

Use GraphApi "me / likes" with an authenticated user, then search for the results and find your identifier for your application / page.
