How to get the client's hostname using gRPC protocol #779

Open alexandu12 opened 4 years ago

alexandu12 commented 4 years ago

Hello,

I would like to know if there is a way to get the client's hostname using Fabio as LB and gRPC protocol.

The setup is : gRPC server - Consul - fabio LB

Right now, the gRPC header remote-addr returns the hostname where fabio is installed. Besides this, I would have expected to have other headers set like: Forwarded, X-Real-Ip, X-Forwarded-For, X-Forwarded-Port and X-Forwarded-Proto, but actually none of them are present.... Is this the expected behavior for gRPC ? https://fabiolb.net/feature/http-headers/

I've tried to configure Fabio to add some headers but none of these seems to work.... proxy.header.clientip, proxy.header.tls and proxy.header.tls.value

Thank you,

Does anyone knows if Fabio (with gRPC protocol) supports this ?
