Glance middleware context process request 'X-Openstack-Request-ID'

[Jorge Cardoso]

The middleware ContextMiddleware from glance (file glance/api/middleware/context.py) processes requests using the method: def process_request(self, req):

During processing, the header variable 'X-Openstack-Request-ID' is accesses to update the request_id.
Nonetheless, other components such as nova seem to be using the variable 'openstack.request_id' when process requests (the variable 'X-Openstack-Request-ID' is added to the header when process responses).
