-    ``http.ServerRequest`` and ``http.ServerResponse``. From the ``ActionContext`` object 
-    ``ac`` shown below, you call ``http.getRequest`` and ``http.getResponse`` to get the

-
-.. _moj_children:
-.. topic:: **Can mojits have child mojits?** 
-
-    Yes, you can configure your application to have mojits that have one or more child 
-    mojits. The parent mojit can execute the child mojits using the 
-    `Composite addon <../../api/classes/Composite.common.html>`_. 
-    See `Configuring Applications to Have Multiple Mojit <../intro/mojito_configuring.html#configuring-applications-to-have-multiple-mojits>`_ 
-    and `Composite Mojits <../topics/mojito_composite_mojits.html#composite-mojits>`_. 
-
-    You can also use frame mojits, such as `HTMLFrameMojit <../topics/mojito_frame_mojits.html#htmlframemojit>`_ 
-    that can execute one or more child mojits.       
-
-------------
-
-
-.. _moj_objects:
-.. topic:: **How do mojits share objects?** 
-
-    You create an application-level middleware or an ActionContext addon that all mojits 
-    can access. Your mojits can use this middleware or the ActionContext addon to share 
-    objects. See `Creating Addons <../topics/mojito_extensions.html#creating-new-addons>`_ 
-    and `Middleware <../topics/mojito_extensions.html#middleware>`_ for implementation 
-    details.
-
-------------
-
-.. _moj_dynamic_creation:
-.. topic:: **Can mojit instances be dynamically defined and then run?** 
-
-    You can run dynamically defined instances of mojits that you created with the Mojito 
-    command-line tool. You would create these instances in a mojit controller using the 
-    ``ActionContext`` object with either the ``_dispatch`` or ``execute`` methods. 
-    See `Running Dynamically Defined Mojit Instances <../topics/mojito_run_dyn_defined_mojits.html>`_

-.. _moj_resources: 
-.. topic:: **Is there a way to make all of the resources, such as assets, addons, binders, 
-           models, of one mojit available to other mojits?**
-
-    To make the resources of one mojit available to other mojits, you set the ``appLevel`` 
-    property in the ``application.json`` file to ``true``. Mojits wanting to use the 
-    resources of application-level mojit must include the YUI module of the 
-    application-level mojit in the ``requires`` array.

-
-.. _moj_names_hyphens:

-
-    The ECMAScript syntax for ``Identifiers`` does not allow hyphens, so Mojito replaces 
-    them with underscores. See the section **Identifier Names and Identifiers** in the 
-    `ECMAScript Documentation <http://www.ecmascript.org/docs.php>`_ for the syntax rules 
-    for ``Identifier`` and ``IdentifierName``.

+
+    The controller of your application can get the HTTP response with the ``Http``

+    In the example controller below, the cookie is set to expire in two weeks. 
+    Note that the value for ``maxAge`` is in milliseconds and that you need to
+    require ``mojito-cookie-addon`` and ``mojito-http-addon`` to use the addons.
+

+
+
+       YUI.add('setCookie', function(Y, NAME) {
