Forum OpenACS Q&A: Re: Hello! New to AOLServer and OPENACS. Question...
aolserver's mailing list is at http://listserv.aol.com/archives/aolserver.html (with archives).
before i started using openacs, i used aolserver 4's internet virtual hosting which worked great.
then once i started using openacs, it was much, much more simple. define a url in your site map and use the host-node-map settings in site settings to attach a hostname to a root url.
