CERN httpd (later also known as W3C httpd) is an early, now discontinued, web server (HTTP) daemon originally developed at CERN from 1990 onwards by Tim Berners-Lee, Ari Luotonen[2] and Henrik Frystyk Nielsen.

[3] In August 1991, Berners-Lee announced in the Usenet newsgroup alt.hypertext the availability of the source code of the server daemon (named WWWDaemon) and other World Wide Web software from the CERN FTP site.

[6] The server was presented on the Hypertext 91 conference in San Antonio and was part of the CERN Program Library (CERNLIB).

[2] The development of CERN httpd was later taken over by World Wide Web Consortium (W3C), with the last release being version 3.0A of 15 July 1996.

[8] The initial version was public domain software; the last one was under an MIT License.
