iTools is an utility for configuring your apache based webserver.
It includes ftp, http, https and DNS  servers
It also includes support for other http,https and ftp servers so you dont have to use the internal ones.

Using Apple’s bundled Apache as a point-of-departure, Tenon’s iTools extends this underlying server platform with an Apache 2 implementation, a point-and-click interface and a rich set of new features.

Included with iTools, in addition to extensions and enhancements to the Mac OS X Apache web server, are a state-of-the-art domain name server, a multihoming FTP server, a robust SSL encryption engine to support eCommerce, a powerful caching engine with state-of-the-art proxy support, and a search engine.

All of the tools are supported using a secure point-and-click browser-based administration tool.
