[users@httpd] Controlling access to web site based on domain name

[Rose, John B]

We would like to control access to a web site based on a listed domain and 
redirect any accesses from domains not
listed to a particular web page.

We need to be able to use the domain names and not IP addresses.

Is this something we should be able to do within .htaccess and using Rewrite 
for the redirect or do we need to use something else?

Thanks
