Hi, As everybody knows, OpenStack API supports both XML and JSON formats now. I'd like to prohibit XML format by openstack settings. Is there any way to prohibit XML format? (Of course, I know that proxy server(ex.Apache) can realize it.) Best regards, Rikimaru -- Rikimaru Honjo NTT Software Corporation E-Mail : honjo.rikimaru at po.ntts.co.jp
