The Application and HTTP Modules
The Application and HTTP Modules
This tutorial covers working with application state and application-wide events within your ASP.NET application. In normal desktop applications, the notion of a global meeting place for various parts of an application is well-understood. For example, MFC, a C++ class library supporting low-level Windows development, includes a class named CWinApp that holds state useful throughout the program. This state includes such items as a handle to the current instance of the application, a handle to the main window, and the parameters that were passed in when the application started. The CWinApp class also runs the message loop—something that can be done only within the global scope of a Windows application. A running Windows application contains one and only one instance of the CWinApp class, and it's perennially available from anywhere within the application.
