Header Propagation

What is Header Propagation?

Header Propagation, also referred to as Context Propagation, is the technique by which context is transferred across services and remote processes through HTTP headers.

Client context information is injected into a request, relayed and extracted by a remote application. That application may in turn make additional requests, relaying the original client context information by injecting context into other downstream services calls, etcetera.
