哼，他倒不傻，仗着跟所里的关系，不理会咱们会稽。他到底身手高强，倒地后伸手往后一捞，抓住秦淼纤腰，猛一用劲捏紧。想着一小团黑影顺水漂流而下的情形，她就怎么也止不住眼泪。　　8年后，两人故地重游，景物各异，人事皆非。而阿秀的身世揭密，更是石破天惊，不由人万千感慨。刺绣事业又将两人命运相连。面对小吏、豪强、地痞、奸商对缂针绣的争夺，他们又开始了一段不平常的人生……There is a key point here. Once you get on the CDN, don't disclose the IP address of the source server, otherwise the attacker can bypass the CDN and directly attack the source server. All previous efforts are in vain. Search for "bypassing CDN to obtain real IP addresses" and you will know how rampant the domestic black industry is.If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.
