"""Middleware that ensures x-compute-request-id
|
|
|
|
Using this middleware provides a convenient way to attach the
|
|
x-compute-request-id to only v2 responses. Previously, this header was set in
|
|
api/openstack/wsgi.py
|
|
|
|
Responses for APIv3 are taken care of by the request_id middleware provided
|
|
in oslo.
