Answer / sabari

The Global.asax file is in the root application directory.
While Visual Studio .NET automatically inserts it in all
new ASP.NET projects, it's actually an optional file. It's
okay to delete it?if you aren't using it. The .asax file
extension signals that it's an application file rather than
an ASP.NET file that uses aspx.

The Global.asax file is configured so that any direct HTTP
request (via URL) is rejected automatically, so users
cannot download or view its contents. The ASP.NET page
framework recognizes automatically any changes that are
made to the Global.asax file. The framework reboots the
application, which includes closing all browser sessions,
flushes all state information, and restarts the application
domain.

Answer / abhishek maitrey

Global.asax is a file, as the name suggests that resides in
the root directory (in the global area) of your
application. It is inaccessible over the web but is used by
the ASP.NET application if it is there. It is a collection
of event handlers that you can use to change and set
settings in your site. The events may occur from one of two
places - The HTTPApplication object and any HTTPModule
object that is specified in web.config or machine.config.
