Function to get 'user agent' data

@shyamb So I do have two questions here: Though Appian has provided an ability to limit the concurrent logins, is it a good practice to refrain from concurrent logins(I assume that the solution in this case would be restricting the user to have only one login)? As Appian has an ability to access the application from multiple devices such as tablet, desktop, mobile etc, is it right to ask a user to log out from an device before starting to use another device?
It would be grateful if you could answer my questions incase if you have an experience around this.
