File extension ashx information

The file extension ASHX is one that is associated with a server side script file used to handle HTTP requests and for the display of dynamic content. These files are associated specifically with the ASP.NET web application framework, that forms part of the platform .NET, from Microsoft Corporation used for web page building. The file is a web handler that works in the same way as the .ASPX file only that it is away a step back from the browser level where the C# and HTML mix. The file is also used by Visual Studio .NET.
When users are using the Visual Studio .NET in the visual design mode of the ASP.NET, the file extension ASHX creates pages with the help of two files, the ASPX and the CS files. The ASPX file represents a layout of HTML that is interspersed with code, and the CS file that represents what is referred to as ‘Code Behind’ by Microsoft. The files of this extension are very essential during the output to an xml-consuming client as opposed to a web browser. The creation of real world web applications is made dramatically easy by the ASP.NET.
