"The Apache Software Foundation (ASF) -- developers, stewards, and incubators of 138 Open Source projects -- announced the 15th anniversary of the Apache HTTP Web Server.

"The ASF's first project became the world's most popular Web server software within the first six months of its inception. The Apache HTTP Server today powers nearly 112 million Websites world-wide.
"A triumph for the all-volunteer Foundation, the Apache HTTP Server reliably delivers petabytes of data across the world’s most demanding uses, including real-time news sources, Fortune 100 enterprise portals, cloud computing clusters, financial services platforms, mission-critical military intelligence applications, aerospace communications networks, and more. The server software can be downloaded, modified and installed by anyone free of charge." Source
