htaccess 301 redirect help

[ergesa]

Hi,
I'm trying to redirect old urls of my old web site to new urls to my new web site.
There ara several urls to redirect and I need to redirect them one to one.
My old url is:

http://www.oldsite.com/index.php?page=old-address

And the new url is:

http://www.newsite.com/new-adress

I tried this;

RewriteEngine On
RewriteBase /
redirect 301 /index.php?page=old-address http://www.newsite.com/new-adress

And this;

RewriteEngine On
RewriteBase /
redirect 301 /index.php%3Fpage=old-address http://www.newsite.com/new-adress

but it didn't work. Do you have any idea to help me?

Thanks.
