This seems to block the event from being forwarded to the backend (via proxy_pass). I modified the ngx_http_read_client_request_body() implementation to not override the request's write_event_handler, and everything started working. No more timeouts.</span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1489063930007_280746"><span><br></span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1489063930007_280795"><span id="yui_3_16_0_ym19_1_1489063930007_280794">I don't know enough to understand the ramification of my change, even though it seems to fixed my immediate problem.
