No name or url provided: try to use current_master A name provided with –name but no url defined: try to find a server by name from config An URL starting with ‘http’ provided: try to find a server by url from config An URL not starting with ‘http’ provided: try to find a server by name An URL and a name provided
- If a server is found by name: use entry and update URL to the provided url
- Else create a new entry with the url and name
