How do I use HTTP headers to ignore certain domain names?

[Usalabs1]

I have 1 primary domain name, which is pointing to my IIS 5.0 webserver, I also have about 8 sub-domains, and 2 dynamic hosts, the primary domain name is using dynamic host #1 to direct http requests to my webserver, the other dynamic host is also pointing to my webserver, but, I use the 2nd dynamic host address for an ftp server, the question is, how do I get my webserver to only allow http request from my 1st dynamic host?

Example.

primary domain name=mydomain.com
subdomain1.2.3......=[subdomain1.2.3......].mydomain.com
dynamic1 host name=myhost1.dnshost.org
dynamic2 host name=myhost2.dnshost.org

mydomain.com points to dynamic host1, which in-turn points to my wan ip, dynamic host2 also points to my wan ip.

So that means even though I'm using dynamic host2 for an ftp server, the host name of dynamic host2 can be entered into IE and still get my webserver home page, what I'm looking for, is if the address of dynamic host2 is entered into ie there would be an error 404, but if the address of dynamic host1 is entered it would reach my webserver.

To put is simply, I would like my webserver to deny access from dynamic host2, but allow access from dynamic host1.

But dynamic host2 still be used as an address for an ftp server.

Is this possible, or am I confusing someone?

If I've got this right, you have one site, 3 host headers (plus subs).

remove the host header of the site you want to die.

I have no headers on the IIS webserver, I want to use headers to block requests from one of the dynamic hosts.

Then put host headers in for the site names you DO want to respond, and omit the one that you don't.
