] | There are no sub-actions in an MVC design.
What you can do is set "subaction" as a parameter or argument to the action. If you don't want to use the default `param/value` pairing, you would need to set up a custom route to recognise a single value.
To choose a different view, you use the `ViewRenderer` action helper.... | you can create Facades somewhere else, then write mod\_rewrite to redirect all ^/controller/.\* URLs to /controller/ and redirect all requests in init() method to correspondent method in Facade

``` | When an anchor element is clicked the browser tries to navigate to the URL to which the anchor's `href` attribute points.
It's possible to override this behaviour using the method `preventDefault` on the `event` object that the event handler receives as paramenter.

Let $f(x)$ is a differentiable function in$ [a,b]$.
How using Mean value theorem to show that if $f'(x)$ is bounded in $[a,b]$ then $f(x)$ is uniformly continuous in $[a,b]$?
