I would like to make my NodeBB forum to write a cookie when the I found the function that is executed when user is logged in successfully: authenticationController.onSuccessfulLogin. How to make this function also to write a cookie? I tried to guess, but it did not work: req.cookie('loggedin', '1'); res.cookie('loggedin', '1'); Also I would like this cookie to be removed when the user is not logged in. I need this cookie in order to make another layer of caching (for non-logged in users) using Nginx and to test how it will work. Is it possible this to be made by a plugin?
