This plugin allows you to rewrite the root url of assets, css, and js files. This allows you to load these resources from an external URL improving the page load time by taking advantage of parallel browser requests.
This plugin requires the use of the <a href="https://github.com/voceconnect/voce-settings-api" rel="nofollow ugc">Voce Settings API</a> library.
If using <a href="http://getcomposer.org" rel="nofollow ugc">Composer</a> for dependency management, you can alternatively, after including the plugin files, run composer install to retreive the Voce Settings API dependency.
