Thanks for the reply sfmskywalker,
indeed i must have the ability to create different versions of any content item. What i am really concerned about is SEO: i don't know how it will be affected if i have route like
domain/de-DE/2323/Artikel-Name-auf-Deutsch (i 've taken out the controller/action part from the initial post).
If i understand you correct, you suggest that for the different localized versions of the same content one can have such kind of routes:
domain/Der-Bericht-auf-Deutsch (german version)
domain/Article-written-in-english (english version)
Is the localization module able to do handle this?
