The Web Script Framework is designed according to the Model View Controller (MVC) pattern (sometimes referred to as MVC for the web). While its primary design goal is to ensure that simple web scripts are easy to develop, advanced web scripts can support various features, such as rendering outputs in multiple languages, exposing and adhering to configuration options, and handling HTML form uploads.
You can call existing web scripts or create your own web scripts for new scenarios. For example, you can create your own web script to expose a RESTful interface onto a custom content repository extension.
