пользователь вошел в конфликт с пользователем динамического URL

Question

пользователь вошел в систему, конфликтуя с динамическим URL-адресом пользователя.Я построил приложение так, чтобы, если пользователь вошел в navbar, на нем появилось его фото и его имя с настройками регистра изменений, это в фиксированном меню, и оно работает, поэтому, когда я набираю url dinamca excelu petaqui.com / maumaster переходит на этот URL в зависимости от имени пользователя, а также изменяет профиль входа в систему на отображаемый профиль.Я хотел бы использовать Facebook, где я вошел в систему, но я могу видеть профиль других пользователей, но когда я просматриваю эти профили, он меняет пользователя, вошедшего в систему, на профиль, который я посетил.
