I'm building a Facebook Canvas IFrame application. The application should always have the session_key (fb_sig_session_key) parameter available. Do I need to force the user to login and "add the application"?
I am not using any libraries and am directly working with Facebook's REST web service. I believe all I need to do is redirect the user to a URL just like I am doing when requesting for extra permissions. Can anybody help me on this?
Thanks, Sri
