Thank you for your patch.

If GET requests are not idempotent in your environment, you have a
serious problem regardless of nginx request handling, as browsers
and other clients will not consider these requests non-idempotent,
and will re-try requests as needed. You may want to re-engineer
your request handling instead of trying to introduce workarounds
in nginx.
