There are many sites that are run on the Mac OS using either WebStar or
MacHTTP.
See "http://brad.net/machttp_talk/sites.by.title.html" for a partial list.
I don't mean to be an advocate for the Apple Internet Server products but
they are easy to use and plenty powerful for many server applications.
And NT products are becoming very respectable as well.

_server.html" if you want some recent statistics on server usage.
