"""Middleware that ensures x-compute-request-id
|
|
|
|
Nova's notion of request-id tracking predates any common idea, so the
|
|
original version of this header in OpenStack was
|
|
x-compute-request-id. Eventually we got oslo, and all other projects
|
|
implemented this with x-openstack-request-id.
|
|
|
|
However, x-compute-request-id was always part of our contract. The
|
|
following migrates us to use x-openstack-request-id as well, by using
|
|
the common middleware.
