X-Forward-Proto is always http

[githuberj]

Hello everyone!

I recently enable a service behind kong-oidc that is dependent on a X-Forwarded-Proto Header, but it misbehaved since it was always receiving X-Forwarded-Proto set to HTTP even though the client was using HTTPS to communicate with the Kong gateway

To overwrite the header I used a Kong Post-Function plugin. That made it work.

Do you think this is a bug?
