Cookie remains alive in the browser after logout
Hello, I've finished this video and while mongodb session collection is gone after logging out, chrome cookie is still available. When I log in again it is changed to another one (with another session id). But it is not deleted after logout. Is it normal behaviour after finishing this course and I need to add some code to delete cookies manually or theres something wrong with my code?
Is there any security vulnerability associated with this behaviour? It's good practice to delete cookies after logout I think, but if session id is gone from server memory/ mongoDB database this cookie is useless I guess?
