The Apache HTTP Web server is 15 years old.
It's the most popular Web server in the world - powering more than 112 million Web sites every day.
"The Apache Server started as a fork (an independent development stream) of the NCSA httpd, a Web server created by Rob McCool at the National Center for Supercomputing Applications. Further development to the server ceased after McCool's departure from NCSA in 1994, so an online community of individuals was formed to support and enhance its software via email collaboration. The founding members of that community (the Apache Group) included Brian Behlendorf, Roy Fielding, Rob Hartill, David Robinson, Cliff Skolnick, Randy Terbush, Robert Thau, and Andrew Wilson," according to today's ASF anniversary announcement.
It took just one year for Apache to overtake the NCSA httpd as the number one server on the Internet.
