In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).影片被描述为“对西部题材充满爱意的重塑”。帕丁森饰演的Samuel是一位富有的拓荒者，他冒险穿越边境，为了与一生挚爱Penelope（米娅·华希科沃斯卡饰）成亲。Samuel与一个酒鬼和一匹叫作“奶油糖果”的小型马同行，然而简单的旅程却变得危险重重。Indirect jump instructionAda的男友Akin坦白对她说，这是他和女人的初吻，因为在以前，他只和男人接吻。男友带她回家，碰巧他的室友也在，室友告诉她，他也是他的前男友。她虽然惊讶，但还是接受了。闺蜜提醒她，昨天他喜欢男人，今天他喜欢女人，也许明天他会喜欢人妖。Fah喜欢上了自己的老师，老师也说很喜欢她，结果没多久就又说自己要结婚了，希望Fah去参加婚礼。当然Fah的第一反应是生气地拒绝前往，也痛恨这样的男人竟然有脸来邀请自己参加其婚礼。当然也有男同学的追求。Kate遇到了一个有妇之夫Worawit，竟然是好闺蜜Ada的爸爸。追求者Ben劝告她不要去做别人的小老婆，人家已经有老婆了。可Kate仍执迷不悟。That is.

It implements the same interface as ontology objects. Proxy objects will pass all calling methods to ontology objects. The most basic form of the proxy mode is to control access, while the ontology object is responsible for executing the function or class of the assigned object. Simply speaking, the local object focuses on executing the code on the page, while the proxy controls when the local object is instantiated and used. We have used some proxy patterns in the above monomer patterns, that is, using proxy patterns to instantiate the monomer patterns, and leaving other things to ontology objects.
