Lynx provides a voice-to-speech interface that provides good functionality for people with visual and auditory impairments. In 1993 Lou Montulli upgraded Lynx to 2.0, although Lynx lacked graphics, but the video and audio features were powerful. In 1993, Mosaic was born in the National Supercomputer Application Center (

Defined User Agent string: navigator.useragent The HTTP specification specifies that the browser should send a short user agent string indicating the name and version number of the browser. But in reality it is not so simple. Development history "1" 1993 U.S. NCSA National Supercomputer Center released the world's first web browser mosaic, the browser's user agent string is
clean, easy to configure Web server. No matter what your choice is, there is always a lot of software to meet your needs. In this article, we will analyze and compare a variety of Web servers to provide a basis for users to choose the Web server that best suits them. Writing a basic Web server is very simple, just listen to the right port, establish a connection, and send the data. Writing such a server general and the development of the client generally always mutually complementary developme
Timbena Lee was the first person to use hypertext to share information, he invented the first web browsing WorldWideWeb in 1990, later renamed Nexus, and in March 1991 he introduced the invention to his friend who worked for CERN, and since then The development of the browser is connected with the development of the network.At the time, Web browsers were seen as a useful tool for dealing with CERN's vast phone book, and Web browsers, under the Gopher and teine protocols, allowed all users to eas
The user agent string userAgent can implement four identification functions: String useragent Definition User proxy string: navigator. userAgent The HTTP specification clearly stipulates that the browser should send a brief user proxy string, specifying the browser name and version number. But in reality it is not that simple. Development History [1] in 1993, the NCSA National Supercomputer Center released Mosaic

military; 1991, Berners? Lee defined the hypertext of the WWW way to use the Internet, but at this time the Internet is still not the media, it is just an American university, a way of academic information exchange Until April 1993, when NCSA first browsed mosaic, the Internet was first viewed as a media, and the commercialization of the Internet was officially kicked off. This is because the invention of
title is displayed as part of your browser window (see below). TITLE Title Title element contains your document title and identifies its contents as a global context. Headings are usually displayed somewhere in the browser window (usually at the top), not in the text area. The title is also used for the display of the Hotspot list hotlist or the bookmark list, so the title choice is descriptive, unique, and relatively concise. The title is also used to search for servers in the WAIS service.

Marc Andreesen and its collaborators, NCSA of National Centre for Supercomputing Applications, the University of Illinois at the State Center for Supercomputing Applications, released a browser called Mosaic in 1993.
