More info

Files with the extension ASPX are standard HTML documents in which one or more scripts are embedded. These scripts can be written in VBScript or JScript, the JavaScript alternative from Microsoft. In addition, programs in VB.Net or C #, which are source code files on the server, can be used via the ASPX page.

Since ASPX files are typically executed on a web server, any browser can be used to display the resulting document. Aspx files are similar to PHP or CGI. The users never get to see the actual ASPX file, but only the created HTML page.

ASPX files are just text files that can be processed on an ASP.NET server. They can be opened and edited in any text editor, however it is recommended to use editors with developer functions such as syntax highlighting for easier work.

The extension ASPX is mostly used instead of htm or html on websites, if the server is running under Microsoft IIS and uses ASP.NET. On Linux there is a possibility with mono to develop and host ASP.NET pages on a Linux system (with restrictions).
