## Setup
  
  ```php
  use OpenCloud\Rackspace;
  
  $client = new Rackspace(RACKSPACE_US, array(
  
  ));
  
  $service = $client->objectStoreService('cloudFiles', 'IAD'); # Second argument is the region you want
  ```
  
  ## Temporary URLs
  
  Temporary URLs allow you to create time-limited Internet addresses that allow you to grant access to your Cloud Files
  account. Using Temporary URL, you may allow others to retrieve or place objects in your containers - regardless of
  whether they're CDN-enabled.
  
  ### Set "temporary URL" metadata key
  
  You must set this "secret" value on your account, where it can be used in a global state:
  
  ```php
  $account = $service->getAccount();
  $account->setTempUrlSecret('my_secret');
  
  echo $account->getTempUrlSecret();
  ```
  
  The string argument of `setTempUrlSecret()` is optional - if left out, the SDK will generate a random hashed secret
  for you.
  
  ### Create a temporary URL
  
  Once you've set an account secret, you can create a temporary URL for your object. To allow GET access to your object
  for 1 minute:
  
  ```php
  $object->getTemporaryUrl(60, 'GET');
  ```
  
  To allow PUT access for 1 hour:
  
  ```php
  $object->getTemporaryUrl(360, 'PUT');
  ```
  
  ## Hosting websites on CloudFiles
  
  To host a static (i.e. HTML) website on CloudFiles, you must follow these steps:
  
  1. CDN-enable a container
  2. Upload all HTML content. You can use nested directory structures.
  3. Tell CloudFiles what to use for your default index page like this:
  
  ```php
  $container->setStaticIndexPage('index.html');
  ```
  
  4. (Optional) Tell CloudFiles which error page to use by default:
  
  ```php
  $container->setStaticErrorPage('error.html');
  ```
  
  Bear in mind that steps 3 & 4 do not upload content, but rather specify a reference to an existing page/CloudFiles object.
