CERN httpd (later also known as "W3C httpd) was a "web server ("HTTP) "daemon originally developed at "CERN from 1990 onwards by "Tim Berners-Lee, "Ari Luotonen[2] and "Henrik Frystyk Nielsen.[1] Implemented in "C, it was the first ever web server software.[3]



This "NeXT Computer used by "Tim Berners-Lee at CERN became the world's first web server

CERN httpd was originally developed on a "NeXT Computer running "NeXTSTEP, and was later ported to other "Unix-like "operating systems, "OpenVMS and systems with unix emulation layers, e.g. OS/2 with emx+gcc. It could also be configured as a web "proxy server.[1][3] Version 0.1 was released in June 1991.[4] In August 1991, Berners-Lee announced in the "Usenet newsgroup alt.hypertext the availability of the "source code of the server daemon and other "World Wide Web software from the CERN "FTP site.[5]

The original, first generation HTTP server which some call the "Volkswagen of the Web.[6]

The server was presented on the Hypertext 91 conference in San Antonio and was part of the "CERN Program Library (CERNLIB).[7][8][9]

Later versions of the server are based on the "libwww "library.[2] The development of CERN httpd was later taken over by W3C, with the last release being version 3.0A of 15 July 1996.[1] From 1996 onwards, W3C focused on the development of the "Java-based Jigsaw server.[10]

The initial version was "public domain software; the last one was under an "MIT license.[11]
