Forum OpenACS Q&A: Re: RFC - possible problems with using web forwarding instead of virtual hosting

Having the 3 DNS entries point to the 3 different port numbers on your server, all using the same IP address, means that your URLs will definitely have port number in them. Some people don't like this, they want their publically visible URLs to look like "" not "".

I'm not sure whether there are any other drawback or not. (For example, SSL certificates.)
