The real thing

gistfile1.js

// assume express and all that goodness (I actually am using Kraken)

// my middleware class
var userModel = function(userID){
	return {
		uid: userID,
		logout: function(){
			this.uid=false;
			// how can I access req?
			req.session.destroy(function(){
				// TODO: handle callback
			});
		}
	};
};

// extend req with my class
module.exports = function(){
	return function(req,res,next){
	  req.user = new userModel(uid);
		next();
	}
}

// so essentially when I want to logout I simply use:
req.user.logout();
// how can user.logout access req?
