Static acknowledgement

Return a fixed reply when application processing is unnecessary. This direct response route returns “Request received” at /acknowledgement with status 200.

Limit: “Request received” does not prove submission validation, storage, or processing. If callers need a unique receipt or processing status, let the application provide it.

Visitor message: Request received

In the load balancer’s routes list, direct_response_route matches the path and route_direct_response defines the status and body.

Expected result: /acknowledgement returns 200 and “Request received”; / returns the normal application response. Compare the bodies because both paths can return 200.
