What is the actual pattern for MVC WRT WebApplications?

The confusion is because of the different MVC architechture diagrams floating on the internet: Since the question would be too broad I want to concentrate on the MVC's used for WebApplications.

Say: Zend Framework.

example 3:
                                    
Model-view-controller concept. The solid line represents a direct association, the dashed an indirect association (via an observer for example).

What I am mainly concentrating is on, how the view interacts with controller(s) & model(s) vice versa.

• Should the view interact directly with model(s)?
• Should the model directly update any changes to the view(s)?
• Is the diagram in example2 a misinterpretation of MVC as it looks like its a MVP⁽¹⁾⁽²⁾pattern.
