diffrent domain depend on user groups

[bartek24m]

Hello,
I just wondering if its possible in vbulleting to set various domains depend to my user groups.

For example i have 2 domains

my-old-domain.com AND my-new-domain.com

I would like redicted all my guests to: my-new-domain.com while when visitor logged in they get redicted to my-old-domain.com

Why so mad idea ?

Couse of google filter to my pages and i can't change domain main to my members.

Tell me if it's possible.
Not HOW but just if it's can be done by VBSEO / or my htaccess file
If yes, I will be try someone who do it for me


thank you
