Correlation IDΒΆ
A unique, random correlation ID will be sent with each request.
The value can be set, when creating the Session
object.
If not set, a random ID will be generated automatically.
The header name defaults to X-Request-ID
.
A different one can be set, by passing it with the request_id_header
argument to the Session
constructor.
The name of the header that is sent, will be in the header Access-Control-Expose-Headers
.
If an ID already exists, e.g. when inside a micro services chain, pass the ID on to the Kelvin REST API server with Session(..., request_id="a1b2c3d4e5")
.
