Apache redirect

Hi!

I need to use redirect in apache 2.
I have to redirect all requests, except:
www.xyz.hu
www.xyz.hu/
Every others must have to be:
www.xyz.hu/blah -> www.abc.hu/blah even if the string 'blah' is only one character.
I realized, if the request is only:
www.xyz.hu/
the apache get it like this:
www.xyz.hu/index.html
Many thanks:
