This might be the opposite of what the OP actually wants. I think they want requests to /my-content to actually go to the site at /en/my-content i.e. so the en no longer appears in the URL – nickgrimSep 3 '12 at 13:16
This snippet doesn`t work on my site. i dont know why.
Are there any problems with varnish before the site? – derpietSep 3 '12 at 13:23
