Catch all subdomains

I want to use a blog software that would function on the fly if I can do the following:- Wildcard subdomains means *.[login to view URL], where any thing entered before the domain maps to .domain.com. As an example, [login to view URL], [login to view URL], [login to view URL], and [login to view URL] would all map to the same site. Wildcard subdomains is different from unlimited subdomains which require manual setup - this should all happen on the fly. In order to enable wildcards subdomains, there are some settings that need to be done to NS and Apache configuration. These settings can be different from server to server, but here is is some directional instructions. It can be done by yourself (if you have the technical knowledge) or you can present the following technical information to the hosting support: NS settings: *.[login to view URL] IN CNAME yourdomain.com. Apache server settings: ServerName [login to view URL] ServerAlias *.[login to view URL] I can still use the software with manually set folders if the above is a no go. Thanks Bob Wright ## Deliverables To setup my hosting package to do the above if possible. I will require this facility to just a few of my proposed domains hosted on the same package. ## Platform Windows XP pro. Hosting is a Linux package
