* <li><code>default_cache_config</code> - <code>string</code> - Optional - This option allows a preferred storage type to be configured for long-term caching. This can be changed later using the <set_cache_config()> method. Valid values are: <code>apc</code>, <code>xcache</code>, or a file system path such as <code>./cache</code> or <code>/tmp/cache/</code>.</li>
