Answer 1

Normally Kong will return server headers based on what the headers configuration is, the default value of this configuration is server_tokens, latency_tokens, hence returning Server, Via, and, latencies.
This value is injected to the response after the response transformer plugin run, So that's why you are not able to hide it with response transformer plugin.

Setting headers to off (e.g. headers = off in kong.conf) will prevented Kong to return these values entirely.
