## This 404s in Safari although I get this in the console:

## If I use this everything works fine:

def redirect_unauthorized(where = "#{params[:controller]}_path", 
                          message = "You are not authorized to perform this action.")
  flash[:error] = message
  redirect_to "/"
end
