I think this could be quite easy with query_string
http://www.mysite.com/any.html?lang=en
rewrite to
http://www.mysite.com/any.html
mantaing transport of lang variable and its value
this rule should be valid for every urls in the domain included the domain itself (e.g. http://www.mysyte.com?lang=en), and the value "en" could be whatever lang code ( es,it,fr,de......).
Is that possible?
thanx richardk!
