## Prerequisites

- It is assumed you have users created and configured with relevant access policies, to start with
  use basic "readwrite" canned policy to test all the operations before you finalize on what level
  of restrictions are needed for a user.

- No "admin:*" operations are needed for FTP/SFTP access to the bucket(s) and object(s), so you may
  skip them for restrictions.

## Usage

        final Exception rootCause = new IllegalArgumentException("Root cause");
        final Exception middleCause = new IllegalStateException("Middle cause", rootCause);
        final String message = "Top level SSO error";
        final VaMessenger<FessMessages> messageCode = messages -> messages.addErrorsSsoLoginError(UserMessages.GLOBAL_PROPERTY_KEY);

        // Execute

### Simulate a File { #simulate-a-file }

In this example, we are simulating a file with `io.BytesIO`, which is a file-like object that lives only in memory, but lets us use the same interface.

For example, we can iterate over it to consume its contents, as we could with a file.

Comme il s'agit d'un WebSocket, il n'est pas vraiment logique de lever une `HTTPException`, nous levons plutôt une `WebSocketException`.
