I am very much enthusiastic in fb app development, but from 1st oct 2011 it has been declared by fb that to run fb apps we need https:// server. So it was a sad news for me, because i have normal http:// server and am a student and my previous active apps are getting closed.

But i have some question, recently from last few days i noticed some apps are runs from normal server too like,
<http://whaddapp.com/> one of them, and many more,
how is that possible?? 

Someone please guide me in right direction, is there in hope for me??
