Hi guys, I'm having a problem with my system authorization, I will give a quick explanation of how it works, my system is using FormsAuthentication to login, so it uses a custom AuthorizeAttribute where it user permissions on controllers and action,
This AuthorizeAttribute works so we have a Profile table and a menus table, so it gets more dynamic, but we noticed a problem when creating / editing a profile it keeps the old Authorization until the application is restarted in the visual or in the environment restart session.
