Apache is a widely used web server available for many platforms, and provides a consistant, scalable, and secure mechanism with which to serve web pages. It is the most popular HTTP server on the web.
The name, like everything else in the computing industry
, is a pun
(or terrible joke
, either way). Apache came out of the ash
es of a pile of other servlet components all held together by patches
, and little hack
s. Thus it was a "patchy" server.
(Okay, you can stop groaning now. It was terrible when i first heard that too)
