Description

I want to add a request header in access logback. So, I tried to find some header configuration. I found %header{header_name} configuration, but It works only in logback-access.xml. For reactor netty access log there was no header configuartion.

I tried to use MDC with reactive context. There were some articles like (https://simonbasle.github.io/2018/02/contextual-logging-with-reactor-context-and-mdc/). but I did'nt get.

Please help me with it.
