Facebooker talk - Jan 2008 - Facebook Redirects to Callback Path after log in

Hey,

I am wondering if anyone has run into this issue before.  I can''t seem
to figure out what Facebook is doing.

I have an application that only requires Facebook Authentication, the
user doesn''t need to "add" the app.   So at the top of my
main
controller I have


class GettingStartedController < ApplicationController
	 ensure_authenticated_to_facebook
......


end

I hit the app and get this URL

http://www.facebook.com/tos.php?api_key=442c6504bd2362d8a7fba7303cd583ca&next=&v=1.0#


After I get the log in screen facebook sends a redirect to the CALLBACK path

http://staging.travelerstable.com:8888/?auth_token=8a83bf3c4f33b5cb16d423c292663c59

Anyone else see this?  I don''t think it has anything to do with
Facebooker, or does it?  If you look in the tos url you can see next, I wonder
what that is for.

Dave

I think I''ve seen this with IFRAME apps... I forget what caused it or
how to mitigate.  Anyone else?

Facebook does not "follow" the link the user originally clicked when  
they tripped the "login" filter. Once the user has been logged in  
however that link will work as expected. The way that I got around  
this was adding a before_filter in my application.rb file looking for  
the auth_token and then just redirecting it on to my facebook  
controller.

If you guys want to redirect to the original request after login just  
add the following to your application controller.

  def application_is_not_installed_by_facebook_user
    redirect_to session[:facebook_session].install_url(:next =>  
"#{request.request_uri}")
  end
