Oracle iPlanet Web Server is a web server designed for medium and large business applications. Oracle iPlanet Web Server builds on the earlier Sun ONE Web Server, iPlanet Web Server, and Netscape Enterprise Server products.
Oracle iPlanet Web Server is available on Solaris, Windows, HP-UX, AIX, GNU/Linux, supports JSP and Java Servlet technologies, PHP, NSAPI, CGI, and ColdFusion.
In January 2009, Sun open sourced core components of Sun Java System Web Server 7.0 under the BSD license as Open Web Server.
In 2010, Oracle renamed the product from Sun Java System Web Server to Oracle iPlanet Web Server, although documentation and links are still in the process of being updated to reflect this.
