PR #27761 replaced `oxy.Forwarder` with `httputil.ReverseProxy`. The new forwarder based on `httputil.ReverseProxy` is appending the `X-Forwarder-For` header values instead of replacing them. This PR fixes that behavior and forces the XFF header to be a single value. Signed-off-by: Tiago Silva <tiago.silva@goteleport.com>
