What is an ASPX file?

An .ASPX file is a Microsoft Extended Active Server Page file.

ASPX stands for Active Server Page Extended file. These files are often used for web forms on the Internet. You can tell when your browser has reached one of these files by the .aspx extension that will appear at the end of the URL in the address bar. For example, if you were to arrive at http://www.abc.com/form.aspx, you would know you were at an active server page.

Developed by Microsoft, these server-generated web pages may often contain C# code or VBScript. The files are commonly created using Microsoft Visual Web Developer and are designed for use within the Microsoft ASP.Net framework.
