When you design a ColdFusion application, you must map the directory structure. This activity is an important step in designing a ColdFusion application. Before you start building the application, you must establish a root directory for the application. You can store application pages in subdirectories of the root directory.
The following sections describe how you determine where to place your application pages and the Application.cfm and OnRequestEnd pages in a directory structure. For more information on how to define and use the Application.cfm page, see Creating the Application.cfm page.
