Oh, Marcus, indeed you're right! :D

I've just tried out the following and it works:

    location /blah {
        echo_duplicate 1 "$arg_callback(";
        echo_location_async "/data?$uri";
        echo_duplicate 1 ")";
    }
    location /data {
        echo_duplicate 1 '{"dog":"$query_string"}';
    }

For request

     GET /blah/9999999.json?callback=ding1111111

you get the response

     ding1111111({"dog":"/blah/9999999.json"})

It should not be hard to hook up fastcgi and memcached settings to
that /data location ;)

It's really a shame that I didn't propose the ngx_echo module written
by myself :P

Enjoy!
