How to cache external Javascript files?

What is the best way to add JavaScript or CSS files of modules in the Yii framework?

• If you want to locate javascript or css files into a module of your yii application, then the file would be placed into your protected folder. But you can not access your javascript or css files outside your proteced folder.

• Answer:

  Possible solution: Add to the module's  xxxModule.php file, into the init() function this code: $urlScript = Yii::app()->assetManager->publish(Yii::getPathOfAlias('MODULE_NAME').'/js/script.js', false, -1, true); Yii::app()->clientScript->registerScriptFile($urlScript, CClientScript::POS_HEAD);
