Some remarks on the difference between traditional MVC and web-MVC (was: Re^2: Implementing Model-View-Controller)
in thread Implementing Model-View-Controller
First off, since the web mostly works with HTML pages that can only be updated via request/response actions (I'm ignoring flash), you can't really have a model update the view's output directly. Also, there are so many possible views that updating them all would be very inefficient.
