How to use HTTP 2 without HTTP/1.1 upgrade for a single HTTP backend service? With curl, I can do
--http2-prior-knowledge to connect to a server that requires HTTP/2. Is there any way to do the same with traefik? Without doing that, curl will give this error
curl: (1) Received HTTP/0.9 when not allowed and with Traefik, it gives
Internal Server Error
The backend service requires HTTP/2 on initial connection which I believe caused the above error with curl.
