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. [1] Implemented in C, it was the first web server software.
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] Version 0.1 was released in June 1991. [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. [4] [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). [4] [7]
Later versions of the server are based on the libwww library. [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. [1] From 1996 onwards, W3C focused on the development of the Java-based Jigsaw server. [8]
The initial version was public domain software; the last one was under an MIT License. [9]
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.
Sir Timothy John Berners-Lee, also known as TimBL, is an English computer scientist best known as the inventor of the World Wide Web, the HTML markup language, the URL system, and HTTP. He is a professorial research fellow at the University of Oxford and a professor emeritus at the Massachusetts Institute of Technology (MIT).
The World Wide Web is an information system that enables content sharing over the Internet through user-friendly ways meant to appeal to users beyond IT specialists and hobbyists. It allows documents and other web resources to be accessed over the Internet according to specific rules of the Hypertext Transfer Protocol (HTTP).
NCSA Mosaic was among the first widely available web browsers, instrumental in popularizing the World Wide Web and the general Internet by integrating multimedia such as text and graphics. Mosaic was the first browser to display images inline with text.
WorldWideWeb is the first web browser and web page editor. It was discontinued in 1994. It was the first WYSIWYG HTML editor.
ViolaWWW is a discontinued web browser, the first to support scripting and stylesheets for the World Wide Web (WWW). It was first released in 1991/1992 for Unix and acted as the recommended browser at CERN, where the WWW was invented, but eventually lost its position as most frequently used browser to Mosaic.
Robert Cailliau is a Belgian informatics engineer who proposed the first (pre-www) hypertext system for CERN in 1987 and collaborated with Tim Berners-Lee on the World Wide Web from before it got its name. He designed the historical logo of the WWW, organized the first International World Wide Web Conference at CERN in 1994 and helped transfer Web development from CERN to the global Web consortium in 1995. He is listed as co-author of How the Web Was Born by James Gillies, the first book-length account of the origins of the World Wide Web.
The Line Mode Browser is the second web browser ever created. The browser was the first demonstrated to be portable to several different operating systems. Operated from a simple command-line interface, it could be widely used on many computers and computer terminals throughout the Internet. The browser was developed starting in 1990, and then supported by the World Wide Web Consortium (W3C) as an example and test application for the libwww library.
Libwww is an early World Wide Web software library providing core functions for web browsers, implementing HTML, HTTP, and other technologies. Tim Berners-Lee, at the European Organization for Nuclear Research (CERN), released libwww in late 1992, comprising reusable code from the first browsers.
Nicola Pellow is an English mathematician and information scientist who was one of the nineteen members of the WWW Project at CERN working with Tim Berners-Lee. She joined the project in November 1990, while an undergraduate maths student enrolled on a sandwich course at Leicester Polytechnic. Pellow recalled having little experience with programming languages, "... apart from using a bit of Pascal and FORTRAN as part of my degree course."
Dan Connolly is an American computer scientist who was closely involved with the creation of the World Wide Web as a member of the World Wide Web Consortium (W3C).
The World Wide Web is a global information medium that users can access via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet, but the Web is a service that operates over the Internet, just as email and Usenet do. The history of the Internet and the history of hypertext date back significantly further than that of the World Wide Web.
Erwise is an early discontinued web browser, and the first that was available for the X Window System.
Henrik Frystyk Nielsen is a Danish engineer and computer scientist. He is best known for his pioneering work on the World Wide Web and subsequent work on computer network protocols.
MacWWW, also known as Samba, is an early minimalist web browser from 1992 meant to run on Macintosh computers. It was the first web browser for the classic Mac OS platform, and the first for any non-Unix operating system. MacWWW tries to emulate the design of WorldWideWeb. Unlike modern browsers it opens each link in a new window only after a double-click. It was a commercial product from CERN and cost 50 European Currency Units
A web browser is a software application for retrieving, presenting and traversing information resources on the World Wide Web. It further provides for the capture or input of information which may be returned to the presenting system, then stored or processed as necessary. The method of accessing a particular page or content is achieved by entering its address, known as a Uniform Resource Identifier or URI. This may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources. A web browser can also be defined as an application software or program designed to enable users to access, retrieve and view documents and other resources on the Internet.
The Arena browser was one of the first web browsers for Unix. Originally begun by Dave Raggett in 1993, development continued at CERN and the World Wide Web Consortium (W3C) and subsequently by Yggdrasil Computing. Arena was used in testing the implementations for HTML version 3.0, Cascading Style Sheets (CSS), Portable Network Graphics (PNG), and libwww. Arena was widely used and popular at the beginning of the World Wide Web.
The First International Conference on the World-Wide Web was the first-ever conference about the World Wide Web, and the first meeting of what became the International World Wide Web Conference. It was held on May 25 to 27, 1994 in Geneva, Switzerland. The conference had 380 participants, who were accepted out of 800 applicants. It has been referred to as the "Woodstock of the Web".
Dave Raggett is an English computer specialist who has played a major role in implementing the World Wide Web since 1992. He has been a W3C Fellow at the World Wide Web Consortium since 1995 and worked on many of the key web protocols, including HTTP, HTML, XHTML, MathML, XForms, and VoiceXML. Raggett also wrote HTML Tidy and is currently pioneering W3C's work on the Web of Things. He lives in the west of England.
ENQUIRE was a software project written in 1980 by Tim Berners-Lee at CERN, which was the predecessor to the World Wide Web. It was a simple hypertext program that had some of the same ideas as the Web and the Semantic Web but was different in several important ways.
