Mod rewrite

[lumir01]

Hello, need a help with mod_rewrite

RewriteEngine on

RewriteCond %{HTTP_HOST} !^{www.domain.cz$}
RewriteCond %{HTTP_HOST} ^domain.cz$
RewriteRule ^(.*)$ http://www.domain.cz [R=301]

RewriteRule ^([/.]+)/?$ index.php?page=$1 [L]

I need to add next rule like this

www.domain.cz/sk/something =>
www.domain.cz/index.php?page=something&language=sk

Everythink what was written before should work normaly.

Thanks for help.
Petr
