redirect a sub forum to another domain

[newbies]

Hello,
I tried to set up a redirect and have put this in .htaccess file

Redirect 301 /forums/index.php?forum=1 [example.com...]

I also tried:
RedirectMatch 301 ^/forums/index\.php?forum=1 [example.com...]

It didn't work,and when I typed the URL /forums/index.php?forum=1, it does go to the other domain. I think the problem lies in the part "index.php?forum=1".

Any clues? Thank you.

A quick Google search [google.com] turned up:
[webmasterworld.com ], which should point you in the right direction; if you still have problems, let us know.
