Hi Sopra,
Szekely is right, the 404 redirect component is only activated when a page is not found.
It's purpose is to handle 404 errors gracefully, redirecting the user to the correct item or to a search.
If Artio is generating two different URLs for the same item, that is an issue with Artio SEF, not 404 redirect.
Secondly, did you install the RD Add PHP mambot / plugin ?
You posted your default 404 page and the mambot tag shouldn't show up if that mambot is installed.
You can get it here :

Add PHP is required for 404 Redirect to function.

Yes, the 404 component is working great! just that I have that issue with duplicate content on different urls, I will try to find an workaround for this one (if you are thinking on anyone, pls let me know), and now I have like 3 options: a javascript menu, not having two menu items linking to the same component or changing somehow in the "View/Edit SEF Urls" from JoomSef backend.
