Redirect URL with fancy URL turned on

[blazejs]

Have you tried making those pages private? (won't be redirected, but not indexed nor visible)

I did. But private pages are not visible when admin is logged out.

What does it do? "Page not found"...?

Is your site at the root of the domain? (RewriteBase / in .htaccess)

Site is in the root. Redirecting had no effect at all. I'll give you real sample. There's e.g. a page:

www.silnikidomaszyn.pl/o1silniki/ that I don't want to have indexed as this is used for left column content on correct page www.silnikidomaszyn.pl/silniki-do-maszyn/ (I just want that to be editable for client)

I'd like to redirect that first page to the second one, but

Redirect 301 /o1silniki http://www.silnikidomaszyn.pl/silniki-do-maszyn/

takes no effect - I got something like this: http://www.silnikidomaszyn.pl/silniki-do...=o1silniki and it displays content of page with slug o1silniki.

I'm not programmer so it's not that clear to me.
