Hi,  
I am using rails 2.2. I am trying to develop an application in  
facebook.  
I installed gem rfacebook (0.9.8) and also I installed plugin  
“rfacebook” by using “ruby script/plugin install  
[http://rfacebook.rubyforge.org/svn/trunk/rfacebook/plugins/rfacebook](http://rfacebook.rubyforge.org/svn/trunk/rfacebook/plugins/rfacebook)”  
command.  
I added a line “before\_filter :require\_facebook\_login” in  
application.rb.  
Whenever I am hitting my application URL  
“[http://localhost:3000/socialrecipetushar](http://localhost:3000/socialrecipetushar)” it is asking me for login to  
face book. After I am entering my valid facebook id and password it is  
going in infinite loop. I checked the log and it is giving an error like  
this

“Processing RecipesController#index (for 127.0.0.1 at 2009-03-18  
07:10:28) [GET]

Filter chain halted as [:require\_facebook\_login] rendered\_or\_redirected.  
Completed in 0ms (View: 0, DB: 0) | 200 OK  
[[http://localhost/socialrecipetushar/recipes](http://localhost/socialrecipetushar/recipes)]”

It seems to be it is not able to take session. I am not able to tackle  
the problem Can anybody give me solution to this problem?

Thanks,  
Tushar
