 Correlation ids for Dropwizard applications. They are useful to match requests between different components.
 - Correlation ids are sent from one system to another using an http header in requests and responses. The default http header is `X-Correlation-Id`.
-- When the server processes a request, its correlation id (or a random UUID if not available) is put into [slf4j mapped diagnostic context (MDC)](https://www.slf4j.org/manual.html#mdc). The default MDC key is `CorrelationId`.
+- When the server processes a request, its correlation id (or a random UUID if not available) is put into [slf4j mapped diagnostic context (MDC)](https://www.slf4j.org/manual.html#mdc). The default MDC key is `correlationId`.
