What is a .ASAX file?
The .ASAX file extension is associated with ASP.NET Server Application Files. These files are important for websites built using ASP.NET, a framework for building web applications. The .ASAX file contains code that helps the website respond to specific events that occur on a server, such as when the application starts or stops, or when there are errors or exceptions that need to be handled globally across the application.
The code inside an .ASAX file is executed automatically by the ASP.NET framework when certain events happen. This makes it useful for setting up the application or cleaning up resources when the application is shutting down. The file is usually named Global.asax and is located in the root directory of the ASP.NET application.
To work with .ASAX files, you typically use a program like Microsoft Visual Studio 2022 or newer versions. This development environment allows you to write, edit, and debug the code in .ASAX files.
It's important to note that .ASAX files are not meant to be accessed directly via a web browser. Any attempts to request the .ASAX file directly through a URL are automatically blocked by the server to protect the code and functionality from unauthorized access. This means that external users cannot see or download the source code from these files.
In summary, .ASAX files play a crucial role in managing how an ASP.NET web application behaves during key events throughout its lifecycle. They are handled by the server internally and are not accessible to the public. To edit these files, developers use specialized software like Microsoft Visual Studio.
