Allow an action once per session

Question

I have a site that tracks video views... every time the controller is called. One could flood their own video views with some heavy F5ing.

How to make it so a view counts or a method runs only once per session?

def show
  new_views = @video.views + 1
  @video.update_attributes(:views => new_views)
end

You can create a session variable, probably upon login, like :

session[:is_logged] = 1

Then, every time you are about to increment the counter, just check this variable.
