URL rewrite with an already rewritten URL

Question

I want to implement a redirect via .htaccess from the old URL:

http://derpiet.de/photos/ireland 

to the URL:

http://derpiet.de/photos/alben/2013/07/ireland

The system in the background is koken (http://koken.me).

Is it possible?

Answer 1

So, this will work:

RewriteCond %{REQUEST_URI} ^/photos/ireland/$
RewriteRule .* alben/2013/05/ireland [L,R=301]
