• Sample usage:

var session = $.session;
var response = require('http/v4/response');

var username = session.getUsername()
var timeout = session.getTimeout()
var token = session.getSecurityToken()
var authType = session.authType

// Check the language of the session
response.println("Session language: " +session.language)

// Check if a particular user has the "Administrator" role
if (username === "dirigible" && session.hasAppPrivilege("Administrator")) {
    // Check a specific system privilege for that user
    if (session.hasSystemPrivilege("Dirigible")) {
        // Perform some operation with his session's information
        response.println("Username: " +username+ " with session authentication type: " +authType+ " token: " +token+ " and timeout " +timeout);
    }
} else {
    // Assert that the user is a Developer in all other cases
    try {
        session.assertAppPrivilege("Developer");
        // Check the authentification type
        if (authType === "BASIC") {
            // Use the information from the current session
            response.println("Username: " +username+ " with session authentication type: " +authType+ " token: " +token+ " and timeout " +timeout);
        }
    } catch(error) {
        //Display the missing role that was being asserted
        response.println("User does not have the role: " +error.privilege)
    }
}

// After all calls are complete, check the invocation count of the current session
response.println("Invocation count: " +session.getInvocationCount());
