'''NCSA HTTPd''' is an early, now discontinued, [[web server]] originally developed at the [[National Center for Supercomputing Applications|NCSA]] at the [[University of Illinois at Urbana–Champaign]] by [[Robert McCool]] and others.<ref>{{cite web |title=NCSA HTTPd Acknowledgements |url=http://hoohoo.ncsa.uiuc.edu/docs/acknowledgement.html |archiveurl=https://web.archive.org/web/20090416132804/http://hoohoo.ncsa.uiuc.edu/docs/acknowledgement.html |archivedate=2009-04-16}}</ref> First released in 1993, it was among the earliest web servers developed, following [[Tim Berners-Lee]]'s [[CERN httpd]], Tony Sanders' Plexus server, and some others. It was for some time the natural counterpart to the [[Mosaic (web browser)|Mosaic]] [[web browser]] in the [[client–server]] [[World Wide Web]]. It also introduced the [[Common Gateway Interface]], allowing for the creation of dynamic websites.

After [[Robert McCool]] left NCSA in mid-1994, the development of NCSA HTTPd slowed greatly. An independent effort, the [[Apache HTTP Server|Apache]] project, took the codebase and continued; meanwhile, NCSA released one more version (1.5), then ceased development. In August 1995, NCSA HTTPd powered most of all [[web server]]s on the [[Internet]];<ref name=":0">{{cite web|title = Web Server Survey {{!}} Netcraft|url = http://news.netcraft.com/survey/|website = news.netcraft.com|access-date = 2016-02-16}}</ref> nearly all of them quickly switched over to Apache. By April 1996, Apache passed NCSA HTTPd as the No. 1 server on the Internet, and retained that position until mid-to-late 2016.<ref name=":0" />
