I successfully completed a log out and then tested accessing my Shovell site via the Firefox Back button. This took me back to the previous page, and allowed me to link from there to a Story page, where I was able to vote even though the 'Not Logged in.' was present.

Am I missing something? I thought setting session[:user_id] & @current_user to 'nil' would stop this possibility?

Thoughts/Guidance appreciated.
