I have my site on domain.com and i'm serving my images and JS from a static domain img.otherdomain.com and js.otherdomain.com. The otherdomain.com points to the same data directory on my server.
Today i've noticed that google is indexing my forum from otherdomain.com and that my forum is available from otherdomain.com
I've had vBulletin + vBSEO installed before and never had a problem with this.
How can i block this so they can't access the forum from otherdomain.com?
Can anyone give me some examples? I don't know exactly how to fix this.
