'''NaviServer'''<ref>[https://sourceforge.net/projects/naviserver/ NaviServer Project]</ref><ref>[https://github.com/naviserver-project/naviserver Official NaviServer NaviServer Source Code Repository]</ref> is a high performance [[web server]] written in [[C (programming language)|C]] and [[Tcl]]. It can be easily extended in either language to create web sites and services; there are over 35 modules available (including database integration or protocol support for [[User Datagram Protocol|UDP]], [[Simple Mail Transfer Protocol|SMTP]], [[Lightweight Directory Access Protocol|LDAP]], [[Domain Name System|DNS]], [[Constrained Application Protocol|COAP]], etc.)

The project is under active development,
NaviServer is mostly written in C with a very well-commented source code, had more than 6,000 commits made by 35 contributors
representing more than 100,000 lines of code.<ref>[https://www.openhub.net/p/naviserver "NaviServer statistics from Open Hub"]</ref> NaviServer is licensed under the terms of the [[Mozilla Public License]] (MPL).

Recent new features include:
* an internal [[watchdog timer|watchdog]] for automatic server restarts
* server internals exposed in a [[Command line interface|command line]] mode
* thread shared arrays (atomic operations, dict support)
* built-in caching with cache transaction semantics (cache commit/rollback)
* hot code [[Hot swapping|swapping]] (update code in the running system without server restart)
* asynchronous spooling of requests and replies
* delivery of static files optionally with [[gzip]] or [[brotli]] compression with automatic re-compression on updates
* selective logging with color highlighting (non-blocking)
* efficient built-in crypto support
* mass [[virtual hosting]]
* [[Byte serving|byte-range requests]] for streaming and resumption of downloads
* rich HTTPS support (server and client-side [[Server Name Indication|SNI]], [[OCSP stapling|OCSP Stapling]])
* built-in HTTP/HTTPS client support, with log-files
* built-in statistics (for [[Lock (computer science)|mutex]] locks/[[Readers–writer lock|rwlocks]], cache, db-handles, ...)
* [[bandwidth management]] via multiple connection thread pools
* [[WebSocket]] and [[IPv6]] support

==History==
NaviServer is based on [[AOLserver]] (version 4.10), [[America Online|AOL]]'s [[open-source software|open-source]] [[web server]]. The NaviServer project started as a [[fork (software development)|fork]] of the AOLserver project in July 2005.<ref>[https://bitbucket.org/naviserver/naviserver/src/naviserver-4.99.0/  "naviserver-4.99.0"]</ref> 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.<ref>[https://philip.greenspun.com/wtr/servers.html "The Web Tools Review on Servers"]</ref> 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 [https://openacs.org/ OpenACS] in particular.
