The reason you were getting an incorrect parameter is that the method,  
“session”, returns a hash, not a string. So calling session returns  
something like {:user =\> “2”}. When you pass a hash to the redirect  
method, it tries to turn it into a string using the “to\_s” method on a  
hash, which just jams the key/value pairs together in a string:

{:user =\> “2”}.to\_s

# =\> “user2”

If I understand what you are trying to do, you should specify the user  
key in your session in your controller’s redirect method:

:action =\> ‘new’, :result =\> session[:user]

that will redirect the browser to the URL:

test\_controller/new?result=2

Good luck,
