This was improved and developed to produce ASP 2.0 released in 1997 as part of IIS 4.0, followed by ASP 3.0 in 2000 as part of IIS 5.0. This lead on to ASP+ in 2001 which was an early version of Microsofts ASP.NET framework in use to this day. You can find out more about the history of classic ASP in our post here.
