"... describes the history of AOLserver -- from its inception as NaviServer to its move to open source -- and offers a comparison of AOLserver and Apache."

"with its 17 million subscribers, America Online is fielding 28,000 hits per second across all of its various Web services and servers. Now that's scalability."

"AOLserver was built in 1994 by Jim Davidson and Doug McKee, two Unix wizards from NaviSoft, as part of an end-to-end Web publishing system."

"America Online later bought NaviSoft and renamed it AOLserver. And now the source code to that server is free and available to anyone who cares to download it..."

"With a process-pool Web server such as Apache, nothing stops you from linking in the Oracle C libraries. Your Apache server can then function as an Oracle client. However, in this scenario no way exists to share a database connection among Apache server processes. What's the bottom line difference? A site like http://photo.net can serve 700,000 hits per day to about 120 simultaneous users at once, with one AOLserver process holding open eight connections to Oracle. That's a total of nine Unix processes (one AOLserver, eight Oracle). With Apache, providing the same level of service from Photo.net would require 120 Apache server process, each of which held open two connections to Oracle: 360 processes total."
