The NCSA HTTPd
was a Web server
originally developed at the NCSA
by Marc Andreessen
and others. It was the second web server developed, following Tim Berners-Lee
's first web server developed at CERN
. It was for some time the natural counterpart to the Mosaic web browser
in the client-server World Wide Web
. It also introduced the Common Gateway Interface
, allowing for the creation of dynamic websites.
Development of NCSA HTTPd was suspended in 1998, but the code lives on the Apache project, which now runs approximately two-thirds of Internet web servers.
