Удалить кеш на HTTP-сервере Python ⇐ Python

[Anonymous]

Я нашел этот сервер в Интернете и немного отредактировал его:

Код: Выделить всё

Сервер работает нормально, и мне нужно удалить кеш. Когда я пытаюсь обновить изображение со страницы html с тем же именем, сервер возвращает мне кэшированное изображение...
