In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.原以为敬文哥和大姐姐吃了饭就会出去的，谁知等了这半天也不见两人出去。　　明末，皇上病重，东厂魏公公（徐少强 饰）妄图夺权。武当弟子卓一航（施俊喆 饰）奉命护送红丸给皇上治病，途中被明月寨人袭击。交锋中，卓一航发现袭击者是自己儿时所救的狼女练霓裳（张维娜 饰），两人相认，互表心意，相约浪迹天涯。然而，爱人却敌不过奸人陷害，卓一航误会练霓裳杀害武当掌门。练霓裳被捕入狱，伤心欲绝一瞬白头，武力大增……You can see that PizzaStore depends on a SImpleFactory, which depends on an abstract pizza.
