# Note: a configmap is needed to make the rate limit deployment work properly, for example:
#
#  apiVersion: v1
#  kind: ConfigMap

	// 1xx class or the modified headers are trailers.

	// There are two ways to set Trailers. The preferred way is to
	// predeclare in the headers which trailers you will later
	// send by setting the "Trailer" header to the names of the
	// trailer keys which will come later. In this case, those
	// keys of the Header map are treated as if they were
	// trailers. See the example. The second way, for trailer
