The asa file extension is also reported to be used for some Active Server document format.

Active Server Pages (ASP) is Microsoft's first server-side script engine for dynamically-generated web pages. It was initially marketed as an add-on to Internet Information Services (IIS) via the Windows NT 4.0 Option Pack, but has been included as a free component of Windows Server since the initial release of Windows 2000 Server.

Programming ASP websites is made possible by various built-in objects. Each object corresponds to a group of frequently-used functions useful for creating dynamic web pages. In ASP 2.0 there are six such built-in objects: Application, ASPError, Request, Response, Server, and Session. Session, for example, is a cookie-based session object that maintains variables from page to page. Web pages with the ".asp" file extension use ASP, although some Web sites disguise their choice of scripting language for security purposes. The ".aspx" extension is not an ASP page, but an ASP.NET page, another server-side scripting language from Microsoft, based on a mixture of traditional ASP, and Microsoft's .NET technology. Most ASP pages are written in VBScript.
