Building e-Commerce Sites with the .NET Framework

HttpApplication

The HttpApplicaton (Application) object allows the sharing of data across all sessions of an ASP.NET application. The ASP.NET Application object adds almost 30 new properties, methods, and events. Compare that to ASP 3.0, where the only events were Application_ OnStart and Application_OnEnd, the only methods were Lock() and UnLock(), and the only properties were Contents and StaticObjects. Tables C.6 through C.8 show the new properties, methods, and events.
