X-Reqid

X-reqid correlates HTTP requests between a client and a server. A client can send an HTTP header X-Request-ID: some-value. The server should use the provided value and provide it in any requests that it makes to backend services for the purpose of serving the initial request. When sending the response, the server will return the same header back to the client. For the purpose of tracing, the server will include the value into its logs, to enable correlating requests and responses with the corresponding logs.
