When the processing capacity of our server is greater than that of the attacker, these attacks are nothing to the server. Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.我看大家还是出去吧，也省得耽误了队长歇息。　　2006年，《快乐的大脚》横空出世，成为了当年动画Lighten…,范青笑道：是啊。愣了会，他才失笑摇头，心想小叔肯定也在怀疑爹。《雷霆扫毒》毒品调查科行动组高级督察向荣（苗侨伟饰）嫉恶如仇，与情报组高级督察韦世乐（林峯饰）亦师亦友，合作无间，为警队屡破毒案。世乐在一次缉毒行动中，发现蛛丝马迹，向荣极有可能是勾结毒犯的神秘黑警。世乐开始暗中调查向荣，加上心术不正的行动组总督察潘学礼（黄智贤饰）从中挑拨，多年兄弟连番角力，矛盾重重。另一方面，世乐因调查行动认识线人陈家碧（徐子珊饰），两人暗生情愫，但家碧出身低微，自卑感作祟，刻意逃情，并让爱予一直暗恋世乐的新扎师妹高希璇（官恩娜饰），三人之间有着微妙的感情关系。忍痛让爱的家碧最后走上不归路，选择投向黑帮大佬的怀抱，成为新一代毒后，贩运毒品，挑战警队。世乐痛心疾首，与向荣联手，跟家碧展开一幕幕的毒战。
