Confusion over add on domains and subdomains

[wmguk]

Hey,

Firstly I know the difference between an Add on Domain and a Sub Domain, but why does cPanel create a subdomain as well as the add on domain account?

I have www.mydomain.co.uk but I also want The Genealogist: Search Online Census, Birth, Marriage, Death & Parish Record Indexes and Directories on the same server, but with TOTALLY different content.

When I set it up it works, but it is confusing because The Genealogist: Search Online Census, Birth, Marriage, Death & Parish Record Indexes and Directories seems to create myhobby.mydomain.co.uk and that is not right - I dont get it using my plesk server and If I bought two seperate hosting accounts from a company that wouldnt happen, so I was wondering if there is a way to set cPanel to not use the subdomain system as well?

Thanks for any info.

An addon domain is a special type of subdomain. An addon domain is a normal subdomain, except that it has a ServerAlias directive in the main domain's <VirtualHost> container in the httpd.conf file that makes content for the addon domain be served from the subdomain's document root. An addon domain may be loaded in a browser by calling either the domain name or subdomain name.

There is no direct equivalent to this in Plesk, and cPanel does not have a direct equivalent to Plesk's "standard forwarding" and "frame forwarding."
