I have the following "question/problem" :

I have 2 languages, english (en-EN) and french (fr-FR) on my DNN 4.5.1.
But by default, the language parameter is not passed into the URL. Consequently, I have three URLs for the same page:

1/ http://domainame.com/tabid/xx/Home.aspx 
2/ http://domainame.com/tabid/xx/language/fr-FR/Home.aspx
3/ http://domainame.com/tabid/xx/language/en-EN/Home.aspx

I would like to get ride of URL No 1/
How could I achieve this, to force the language to appear in the URL ???
{Otherwise, I have SEO problems since one page (language) is indexed twice.}

Any possibility or setting ???

PS: Do not look at my prod site (it is still working with an url rewritter & Apollo MLSelector, but I would like to get ride of URL Rewritter + MLlanguage to have the path with the language parameter if possible)
