Hum... well ok, if I read it right, it is recommanded to use try_files
instead right ?
Problem is that it seems that try_files is not allowed inside a "if"...

Well.. maybe someone will be able to point me a better conf, here what I'm
trying to do :

        location ~ ^/(media|files|list|album|images)/ {
                root /;
                if ($host ~* "^(.)(.)(.*)\.example.com$") {
                        set $dir1 $1;
                        set $dir2 $2;
                        set $dir3 $3;
                        rewrite ^ /<path>/
www.example.com/$dir1/$dir2/$dir1$dir2$dir3$request_uri? break;
                }
        }

So I should be able to remove the if so try_files might be happy, but I do
not know how to set the 3 dir w/o the if statement..
I tried several things, so far no luck.
