To change the default HTTP header names, used to transfer the tracing context from client to server, it is enough to define two properties only: TracerHeaders.HEADER_SPAN_ID and TracerHeaders.HEADER_TRACE_ID. For example:
| Code Block |
|---|
|
final ClientConfiguration config = WebClient.getConfig(client);
config.getRequestContext().put(TracerHeaders.HEADER_SPAN_ID, "CUSTOM_HEADER_SPAN_ID");
config.getRequestContext().put(TracerHeaders.HEADER_TRACE_ID, "CUSTOM_HEADER_TRACE_ID"); |

It is very important to keep client and server HTTP headers configuration in sync, otherwise the server won't be able to establish the current tracing context properly. |
