How can I programatically assign a visitor group to a user from C#?
I have an iFrame on a page that contains some 3rd party application process (like applying for a loan). When a user begins the application but leaves without finishing it, I want to detect this in JavaScript and make an Ajax call out to the backend informing it of what is occuring. The backend controller action should programatically assign a custom visitor group of 'Prospect' to the current user. Is this possible?
