Finally, the current ASP development environment does not include an IDE or debugger. The response object is used to create output that is returned to the user. Listing One demonstrates using the Response and Request objects. An application is a group of related files stored in an IIS virtual directory and shared by all application users. It is instantiated when the first user requests an ASP file in the application's directory structure after the Web server has been started.
Applications end when the server shuts down.
You can write code to respond to application start and end events, and also attach your own variables to the application object, making them accessible to all application users. Query results, for example, can be stored at a global level that any user can access. An application can use global.asa, an active-server application file read whenever an application or session starts. Global.asa is stored in the root directory of the application, which also includes scripts that respond to start and end events for application and session objects. The session object is similar to the application object, but belongs to a single user.
