- global.asax file is responsible for writing code for global events. These events fire at various points during the lifetime of a web application, including when the application domain is first created.
- There can be only one global.asax file in a Asp.Net application. You can add it through visual studio, Right click on the web site -> Add New Item and then select Global Application Class file type.
- It can’t contain any HTML or ASP.NET tags, it contains event handlers that respond to application events.
- Some of the global events are:
Application_Start(): Occurs when the application starts, which is the first time it receives a request from any user.
Application_End(): Occurs when the application is shutting down, generally because the web server is being restarted.
Application_BeginRequest(): Occurs with each request the application receives, just before the page code is executed.
Application_EndRequest(): Occurs with each request the application receives, just after the page code is executed.
Session_Start(): Occurs whenever a new user request is received and a session is started.
Session_End(): Occurs when a session times out or is programmatically ended.
Application_Error(): Occurs in response to an unhandled error.
Example:
<%@ Application Language = "C#" %>
<script language = "c#" runat = "server">
protected void Application_EndRequest(object sender, EventArgs e)
{
//You can write code here.
}
</script>
