virtual virtual domains

[esromneb]

Hi, I run a web hosting company, and I'm trying to write a webpage that will allow access to domains before dns has updated. Such as: if I buy a domain, add it using webmin - virtual servers, and then want to edit it immediatly before the dns updates. Before I just had a directory of symlinks to the different public_html/ dirs. The problem with this is: my admin domain is:
admindomain.com

so if I visited
admindomain.com/~newdomain/

some pages don't dislpay correctly, and images and such don't work sometimes.

Would there be a way for me to accomplish this task by using:
newdomain.admindomain.com
?

That way if an image was src="/logo.jpg" it would display.

I have apache and bind both configured with wildcards, so now I need to setup a sym link system.

Is there a way I can use php to accomplish this task? Or do I have to make a virtual server in apache for every virtual virtual domain? thanks for your input

Don't use absolute URLs.

But, yes. Out company puts up new customers as newcustomer.outdomain.com and virt_host's the hostname over there.

Do you know how that service is accomplished? Is it configured in httpd.conf? Or is there some other trick? Thanks
