It is important to remember that match-all views are applied only *after*
content-type negotiation is attempted.

Using AjaxView
==============

In applications that use hypermedia or AJAX clients, you often need to render
view contents without the wrapping layout. You can use the ``AjaxView`` that
is bundled with the application skeleton::

// In a controller action, or in beforeRender.
if ($this->request->is('ajax')) {
$this->viewBuilder()->setClassName('Ajax');
}

``AjaxView`` will respond as ``text/html`` and use the ``ajax`` layout.
Generally this layout is minimal or contains client specific markup. This
replaces usage of ``RequestHandlerComponent`` automatically using the
``AjaxView`` in 4.x.

controller that uses the files, and named after the action it corresponds to.
