Abstract: A content server defending system for defending content servers that distribute content registered through the Internet to internet terminals, which are capable of connecting with the Internet, against false access. The system comprises auxiliary servers with which copied content data copied from at least a part of distribution content data registered with the content servers is registered, and which are capable of distributing the copied content data to the internet terminals; an access dispenser for assigning requests from the internet terminals to distribute the content to each of the servers so as to substantially equalize the distribution load on each server; a false access detector for detecting false access to each server; and a false access cutoff for cutting off the communication of false access when the false access detector detects the false access.

Abstract: Disclosed is a high-temperature dry steam cooking utensil which heats and cooks cooking material in a variety of cooking methods like boiling and frying using high-temperature dry steam in an efficient manner without losing moisture and nutrients of the cooking material while preserving the food's own flavor. The high-temperature dry steam cooking utensil comprises a cooking pan for containing water, a tray having a flange for accommodating thereon cooking material, a steam baffle for covering the tray, and a lid for covering the cooking pan. The top portion of the cooking pan is formed of stepped portions for receiving the tray, the steam baffle, the lid. Steam paths are formed between the peripheral of the tray and the inner wall of the cooking pan by cutting partially the stepped portion. Steam generated in the cooking pan is heated in the space between the tray and the inner wall of the cooking pan to a high-temperature dry state.
