Some files in a web application (such as images and sounds) must be stored under the web server's document root in order for the server to access them. The remaining files (such as your components and source code) must be accessible to your application but not necessarily by the web server itself.
In previous versions of WebObjects, it was typical to store the entire project under the web server's document root. This practice has advantages for turnaround time during development. However, in deployment, it presents the possibility of allowing users access to your source code. WebObjects has a "split installation" feature that allows you to install only those files (such as images) that the web server must have access to under the document root. The remaining files can be stored elsewhere.
The same procedure applies to installing WebObjects applications and frameworks. To install:
