History
editNaviServer is based on AOLserver (version 4.10), AOL's open-source web server. The NaviServer project started as a fork of the AOLserver project in July 2005.[5] 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.[6] 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.
