Redirect does not work on nginx
Finally, someone redirected me to the right place

Here's the missing code that does the trick:

location ~ \.php$ {
            error_page 418 = @rewrite;
            recursive_error_pages on;

            fastcgi_split_path_info ^[^=](.+\.php)(/.+)$;
            include fastcgi_params;

            if ( $uri = /index.php ) {
                    break;
            }

            if ( !-e $document_root$fastcgi_script_name) {
                    return 418;
            }

            #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_intercept_errors on;
            fastcgi_read_timeout 240;
            fastcgi_pass  127.0.0.1:9000;
}
