FlowRouter random redirect (instance)

Hi everyone Im trying to redirect a user to a page with random ending (make instances of the same page per user so other users cannot acces the same page) for example I have:

FlowRouter.route('/main',{ name: 'main', action(){ BlazeLayout.render('MainLayout'); } });

I want the user to be redirected to something like:

/main=randomString

(so it will be unique to every user that hits the Main page) help?
