If volume server is started with a separated public port, the public port will
|
|
be more "secure".
|
|
|
|
Public port currently only supports reads.
|
|
|
|
Later writes on public port can have one of the 3
|
|
security settings:
|
|
1. not secured
|
|
2. secured by white list
|
|
3. secured by JWT(Json Web Token)
