How to add logout functionality to an Apprenda deployed application?

We inject into every application a logout handler that you can use throughout your application. In order to implement the logout functionality you would simply direct your users to /__authentication/Logout.aspx

For example if your application's URL is apps.apprenda.local/app1, then you would create a link to apps.apprenda.local/app1/__authentication/Logout.aspx (note that it is 2 underscores).
