I cannot understand how this works. When I create a product in Commerce manager, the url for different languages are created automatically, but they are all the same for the different languages. How do I keep the url-base for the products and the rest of the site.

For example:
All url's in EPiServer will look something like this: http://mysite.com/sv/myarticle (for swedish) and http://mysite.com/en/myarticle, so If So I browse to a product I want the url to look like this: http://mysite.com/sv/myproduct and http://mysite.com/en/myproduct

I tried to set product-urls to /sv/myproduct and /en/myproduct in Commerce manager, but I get a 404 on these request. How do I solve this?
