[ANN] ngx_echo v0.35: ability to POST/PUT local files as subrequest bodies

[Alexander Kunz]

Thanks so much for your detailed answer. Works like a charm :)

But i see i can't access this from LUA?

methods cannot

|echo_location_async|, |

be fixed in the future due to technical problems :)

but is it possible to get

echo_request_body

directly in nginx LUA?

Thanks.

Alexander
