Returning a normal response

In the course of normal processing, the controller object's render method is called to generate a Web page to be returned to the client. This method may be explicitly called by an action method, but is usually implicitly invoked by the controller after the action method completes if it has not already been called and output has not been initiated by some other means such as redirection.

The process by which the render method produces a page is described in Page generation.
