Why redirect_to in around_filter or after_filter won't work?

Question

How to make redirect_to works in those filters?

I\'m trying to change

def start 
  ....
  redirect_to index
end

def end
  ...
  redirect_to index
end

You can change response.location, which has the same effect as calling redirect_to. An example with an after_filter (the same could be done with around):

  after_filter :different_redirect, only:[:create]
  def different_redirect
    if self.status == 302
      response.location = other_thing_path
    end
  end

  def create
    @my_thing = MyThing.new(params[:my_thing])
    respond_to do |format|
      if @my_thing.save
        format.html { redirect_to(my_things_path) }
      else
        format.html { render :action => "new" }
      end
    end
  end
