Exclusive IP

[Dignus]

How can I make an IP exclusive to one website so that when I enter the IP in my browser, the website shows up?

I set the IP in Plesk to exclusive, and set the domain to this IP. But when I enter the IP, I'm getting the default page.

I see in httpd.include the config for this, I can comment it out. But whenever websrvmng is ran, the httpd.include is overwritten.

Thanks.
