Terms of support for x-glance-api-copy-from header in Glance API
I'm using Glance API v1 through REST. POST request to /v1/images supports specifying http URL in x-glance-api-copy-from header. This way we can create big-sized images that would not pass HTTP POST size limit. But it's not documented at http://docs.openstack.org/developer/glance/glanceapi.html. Is it planned to become deprecated or is it just documentation issue?
