Setup
-----

.. code:: php

    use OpenCloud\Rackspace;

    $client = new Rackspace(RACKSPACE_US, array(

    ));

    $service = $client->objectStoreService('cloudFiles');

To access the CDN functionality of a particular container:

.. code:: php

    $container = $service->getContainer('foo_bar');

    $cdn = $container->getCdn();

List CDN-enabled container
--------------------------

To list CDN-only containers, follow the same operation for Storage which
lists all containers. The only difference is which service object you
execute the method on:

.. code:: php

    $cdnService = $service->getCdnService();
    $cdnContainers = $cdnService->listContainers();

    foreach ($cdnContainers as $cdnContainer) {

    }

CDN-enable and -disable a container
-----------------------------------

Before a container can be CDN-enabled, it must exist in the storage
system. When a container is CDN-enabled, any objects stored in it are
publicly accessible over the Content Delivery Network by combining the
container's CDN URL with the object name.

Any CDN-accessed objects are cached in the CDN for the specified amount
of time called the TTL. The default TTL value is 259200 seconds, or 72
hours. Each time the object is accessed after the TTL expires, the CDN
refetches and caches the object for the TTL period.

.. code:: php

    $container->enableCdn();
    $container->disableCdn();

Serving containers through SSL
------------------------------

.. code:: php

    $cdn->getCdnSslUri();

Streaming CDN-enabled containers
--------------------------------

.. code:: php

    $cdn->getCdnStreamingUri();

iOS streaming
-------------

The Cloud Files CDN allows you to stream video to iOS devices without
needing to convert your video. Once you CDN-enable your container, you
have the tools necessary for streaming media to multiple devices.

.. code:: php

    $cdn->getIosStreamingUri();

CDN logging
-----------

To enable and disable logging for your CDN:

.. code:: php

    $cdn->enableCdnLogging();
    $cdn->disableCdnLogging();
