MS SERVER 2008 + IIS7 2 Websites in different IPs, single machine

I saw a neat tutorial… on how to configure 2 websites, locally at least

Scenario I have 2 websites in 2 different machines and I will merge it in one machine (MS SERVER 2008 + IIS7)

example.com = machine-A | example2.com = machine-B

old-example.com = machine-A | machine-B = example2.com + example.com (different IPs)

I follow the site its pretty neat locally but when I test it over the net…
example2.com overpowers the example.com.

How do I fix this.
Thanks a lot!

You need to look into Virtual Hosting, rather than setting it via IP you can actually have htem share the same IP and still host multiple sites from it.

Right, with the use of host headers in IIS. You can use the same IP, you just differentiate each site by a unique host header.

I believe I already specified host headers in IIS7.
I will take a good look at it… thanks guys.
