Re-direct magic...How do they do that?

As an online marketer, I am always trying to improve my websites and save money when I can at the same time. I do my own websites and struggle through the HTML stuff.

My latest idea (not original) is to place several minisites on the same site using re-directs on the default page to send the visitor to the right page for a specific domain. (Bill Myers had an article about this a few weeks back.)

In my research on this I determined that GoDaddy.com where I have my domains registered can point one or more of my domains to my website for $9.95/year/domain. For an additional fee they can "mask" the re-direct so the visitor doesn't know they have been redirected to another site.

My question is "how do they do that?" I think I understand the redirect part, but how do they mask the domain name?

Thanks for any answers...
