The Global.asx file is an optional file that contains code for responding to application level events raised by ASP.NET. This file is also called as ASP.NET application file. This file resides in the root directory of an application. If we are not defining this file in application, the ASP.NET page framework assumes that you have not defined any applicationa/Session events in the application.



Followign are the list of events handled in the global.asax file.

Event: Application_Start

When an application starts. This event occurs only one time in an application’s life cycle. It occurs again when you restart the application. It’s the best place to count number of visitors.

Event: Application_End
