What is an ASPX file?

An ASPX file is a server-generated web page that may contain VBScript or C# code. It is often written with Microsoft Visual Web Developer and designed for the Microsoft ASP.NET framework. ASPX files contain scripts that are processed on the web server and the resulting HTML is sent to the user's web browser.

More Information

ASPX pages are also called ".NET Web forms." They can be identified in a web browser when the URL in the address field ends in ".aspx".

Common ASPX Filenames

Default.aspx - The default webpage loaded when a client browser requests a Web server directory on a Microsoft IIS-based server that uses ASP.NET. For example, when a client requests http://www.sampledomain.com/, the server loads http://www.sampledomain.com/Default.aspx, unless it is configured to load a different file.
