HTTP/2: discard remaining request body after redirect. Previously, if unbuffered request body reading wasn't finished before the request was redirected to a different location using error_page or X-Accel-Redirect, and the request body is read again, this could lead to disastrous effects, such as a duplicate post_handler call or "http request count is zero" alert followed by a segmentation fault. This happened in the following configuration (ticket #1819): location / { proxy_request_buffering off; proxy_pass http://bad; proxy_intercept_errors on; error_page 502 = /error; } location /error { proxy_pass http://backend; }
