The server will generate a correlation ID for every HTTP request and send it in the response through the Correlation-Id response header. This response header name can be customized.

The following example changes the correlation-id-response-header property to "X-Request-Id."
$ bin/dsconfig set-connection-handler-prop \
  --handler-name "HTTPS Connection Handler" \
  --set correlation-id-response-header:X-Request-Id
