Hello, Technically this is not a bug because the RFC describes the header fields as case-insensitive: https://www.rfc-editor.org/rfc/rfc7540#section-8.1.2
Said that, I guess that we can check if there is any way to not modify them at all (it's the golang runtime proxy who does it, we aren't changing them in the code)
Are you willing to contribute with the fix?
Thanks a lot for your quick response. I am really sorry I can't contribute now. Is there any workaround to bypass this as its impacting our logging flow ? Please suggest.
It can't be bypassed AFAIK. Bypass is solving indeed xD The golang proxy is replacing the headers given that they are case-insensitive based on the RFC, so it's not a bug with a workaround, all the requests use the proxy
This is the same problem as with Traefik ingress. We had to use Nginx ingress for a project that had a hard requirement on non-rfc headers. iirc, the issue was opened at the go library level, and it was refused. So I don't think this is something that will be "fixed". The answer is basically "make your code rfc compliant".
