RoR: AuthenticatedSystem incorrectly redirects Safari to Safari

I've been banging my head about this for days now:

I have a RoR application using AuthenticatedSystem that requires authentication for some resources. A before_filter checks if the user is logged in. If not, it grabs request.request_uri and puts it in a session variable (session [: return_to]) and then sends the user to the login page via a 302 redirect message. Then after login, the user is redirected back to the url in session [: return_to].

This works great in IE and Firefox. In Safari, the request.request_uri on the initial before_filter is empty and the session controller is always redirected to the main page.

Has anyone encountered this before? The only clue I have is that the web inspector for Safari doesn't even show a prompt for the start page, only a login prompt. In Firefox I see both requests.

Here before_filter:

def login_required
  if !authorized?
    session[:return_to] = request.request_uri
    redirect_to new_session_path
  end
end

      

        
        
        
      

    

Here's session / create:

def create
  self.current_user = User.authenticate(params[:login], params[:password])
  if logged_in?
    if params[:remember_me] == "1"
      current_user.remember_me unless current_user.remember_token?
      cookies[:auth_token] = { :value => self.current_user.remember_token , :expires => self.current_user.remember_token_expires_at }
    end
    redirect_back_or_default('/')
    flash[:notice] = "Logged in successfully"
  else
    flash.now[:error] = "Authentication failed."
    render :action => 'new'
  end
end

      

        
        
        
      

    

Any ideas?
