You can connect ColdFusion to the built-in web server and to external web servers, such as Apache, IIS, and Sun ONE Web Server (formerly known as iPlanet).
ColdFusion lets you manage web servers when running in the server configuration, in the multiserver configuration, and when deploying on Macromedia JRun in the J2EE configuration. (Some J2EE application servers include web server plug-ins that provide similar functionality.)
