I am currently creating a multilingual site, which is working nice, but i have one question.

When the EPSLANGUAGE cookie is set, IE nl-nl and i visit the homepage, the right page is shown (the dutch one), but the URL keeps the same for all languages....

So when i have the ESPLanguage cookie: nl-nl i want the urls prefixed with the NL prefix: something like www.mysite.com/nl/news/etc

now its showing: www.mysite.com/news/etc

Is this something i can configure in web.config?
