Объясните, как работают сессии в django?

Попробую перефразировать первый вопрос, потому что со вторым разобрался уже, а второй важнее:)
У нас есть user, мы логинимся, в промеж. слое делается хеш и записывается куда-то в приложуху sessions, ставится кука с хешом, дальше идет валидация. Как все эти хеши удалить, закончить все сеансы?

Объясните как настроить статику Django?

Roman Kitaev: для чего URl тогда?

Объясните как настроить статику Django?

Также интересно про MEDIA_ROOT и URL. Из документации:
" FileField.upload_to
Изменено в Django 1.7:

upload_to был обязателен в предыдущих версиях Django.

Путь в файловой системе относительно значения настройки MEDIA_ROOT для определения url."
Для чего здесь MEDIA_URL тогда нужен?
