Constructor Details

#initialize(connection) ⇒ Authentication

Performs an authentication to the Cloud Files servers. Opens a new HTTP connection to the API server, sends the credentials, and looks for a successful authentication. If it succeeds, it sets the cdmmgmthost, cdmmgmtpath, storagehost, storagepath, authtoken, and authok variables on the connection. If it fails, it raises an CloudFiles::Exception::Authentication exception.

Should never be called directly.
