	// Header to hold the audit ID as the request is propagated through the serving hierarchy. The
	// Audit-ID header should be set by the first server to receive the request (e.g. the federation
	// server or kube-aggregator).
	//
	// Audit ID is also returned to client by http response header.
	// It's not guaranteed Audit-Id http header is sent for all requests. When kube-apiserver didn't
	// audit the events according to the audit policy, no Audit-ID is returned. Also, for request to
	// pods/exec, pods/attach, pods/proxy, kube-apiserver works like a proxy and redirect the request
	// to kubelet node, users will only get http headers sent from kubelet node, so no Audit-ID is
	// sent when users run command like "kubectl exec" or "kubectl attach".
	HeaderAuditID = "Audit-ID"
)

Header keys used by the audit system.
