The technology to do with Active Server Pages (ASP) is the successor to SSI that was developed by Microsoft and creates server-side webpages using script language such as VBScript, Perl or JScript. ASP was originally only interpreted by the web server Internet Information Services (IIS). Since then, however, there are also various ports for the Apache web server available. ASP was released in 1996. Based on its possibilities for web programming, one can set this technology on the same level as PHP, PerlScript, CFM and Perl. ASP is no longer being updated by Microsoft. The successor technology ASP.NET replaced ASP with the introduction of the .NET framework in 2002.
