History
NaviServer is based on
AOLserver (version 4.10),
America Online's open-source
web server. The NaviServer project started as a fork of the AOLserver project in July 2005.
[ "naviserver-4.99.0"] It is different by supporting multiple protocols, providing higher scalability through asynchronous I/O and aims to be less conservative with new feature development.
Historically NaviServer was the original name of the server, a closed-source product by a company called NaviSoft in the early 1990s.[ "The Web Tools Review on Servers"] It was bought by AOL in 1995, and released as open-source in 1999 as AOLserver after they released Mozilla. This friendly-fork takes the code back to its original name.
Large applications of NaviServer are the ArsDigita Community System and OpenACS in particular.
