Redirect after domain change

[amagab]

I'm going to move my forum to a different domain. To preserve the current links and SEO I'm looking for a way to redirect.

For example, when someone clicks on an old link: http://old-domain.com/showthread.php?398-Sleeping-Hard I want it to be redirected to the new domain URL: http://new-domain.com/showthread.php?398-Sleeping-Hard

Is it possible? How?

This would be extremely useful for me.

Thanks!

If you own the domain just point it to new one or get host to perm redirect it for you

Thanks for your replies. I'll look closer at the link you posted.

I forgot to mention that I'm splitting my forum between two domains. So some of the links will remain valid and some will have to be redirected. Is that possible?
