Well, there's more than one way to do it, actually. A more concise and
faster version is given below:

location /blah {
echo_before_body "$arg_callback(";

echo_duplicate 1 '{"dog":"$uri"}';

echo_after_body ")";
}

The "echo_before_body" and "echo_after_body" directives work exactly
in an output filter. And no extra cost of subrequests is needed here
:D

The output might be a bit ugly due to 1 extra new line:

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

But...it's not that bad anyway ;)

TMTOWTDI!
