different header depending on what url website is typed in?

[Relientk]

I was wondering if any one knows if there is a mod or some way that you can have a different header/logo show up depending on the url that is typed in.

For example-

You are using ONE database the SAME forum. But you have TWO url's that go to this ONE forum. So for example you have siteone.com and sitetwo.com its the same site but when url siteone.com is the url typed in the address bar it will load the graphic/header that says siteone.com and then vise versa if sitetwo.com was typed in.

I seen this mod that will load different banners according to the time- https://vborg.vbsupport.ru/showthread.php?t=236726 basically that's what I'd like to do but for it to change for whatever domain.com/url is typed in.

I appreciate any help! Thank you!
