Netscape Web Server was an integrated software platform for developing and running transaction-oriented business applications on the web. It was developed originally by Kiva Software, which Netscape acquired in 1997.
When Netscape and Sun Microsystems formed the Sun-Netscape Alliance in 1999, the Netscape Web Server was chosen as the basis for their iPlanet Application Server offering over the NetDynamics Application Server,[1][2] which had been acquired by Sun in 1998.
