Hi, It seems that there is a bug in QUIC when using a fastcgi backend:
As soon as the size of the uploaded data is more than bufsize, the server returns 400 Bad request and shows PH-- in the logs.
The problem occurs with both haproxy 2.8.1 and 2.9-dev2 (both build quictls OpenSSL_1_1_1u-quic1).
When using h2 or an http backend, everything is ok. Is it a known problem? Thanks, --yas
