I'm developing a site for a client. They've got a site now that's hosted at hosting.com. I'm going to move them to my VM hosting solution at edge web but I want to run some tests and have the client approve the site before changing the name servers to the new site/hosting location.

How do I make this happen? I'm running a red hat/Apache on linux for the edge web hosting. I don't have control of the domain name (i.e. the client controls that right now).

Edgeweb has set up a dns zone for the domain name so that when the time comes to switch we're ready to go.

I'm a web developer and I understand the technologies that make a user experience 'work' but I'm unfamiliar with the server jargon and all that so, please be patient.

Thanks in advance.
