A: Urbana, Illinois, United States
In April 1995 Robert McCool, author of the original NCSA HTTPd web server, and a group of collaborative software developers initially known as the Apache Group, made the first official public release (0.6.2) of the Apache HTTP Server software. McCool wrote the first version of NCSA HTTPd as an undergraduate at the University of Illinois at Urbana-Champaign, while working on the original NCSA Mosaic team.
"Since April 1996 Apache has been the most popular HTTP server software in use. As of September 2009 Apache served over 54.48% of all websites and over 66% of the million busiest."
"There have been two explanations of the project's name. According to the Apache Foundation, the name was chosen out of respect for the Native American tribe of Apache (Indé), well-known for their endurance and their skills in warfare. However, the original FAQ on the Apache Server project's website, from 1996 to 2001, claimed that The result after combining [the NCSA httpd patches] was a patchy server. The first explanation was supported at an Apache Conference and in an interview in 2000 by Brian Behlendorf, who said that the name connoted 'Take no prisoners. Be kind of aggressive and kick some ass'. Behlendorf then contradicted this in a 2007 interview, stating that 'The Apache server isn't named in honor of Geronimo's tribe' but that so many revisions were sent in that 'the group called it 'a patchy Web server' '. Both explanations are probably appropriate" (Wikipedia article on Apache HTTP server, accessed 02-02-2010).
