Since http is based on tcp, You need to complete a three-way handshake to establish a tcp connection before you can start http communication, Therefore, when http flood attacks are carried out, it is not possible to use forged source ip addresses to launch attacks. An attacker will typically use an http proxy server, Not only can the source be hidden from being traced, It also improves attack efficiency-after the attacker connects to the proxy server and sends the request, You can directly disconnect from the proxy server and start connecting to the next proxy server, At this time, the http connection between the proxy server and the target web server is still maintained, and the web server needs to continue to accept and process data. An efficient http flood attack should continuously send http requests for different resources and pages, and request resources that cannot be cached as much as possible (such as keyword search. User-related information, etc.)

RST means reset, which is used to close the connection abnormally. It is indispensable in TCP design. When sending RST packets to close the connection, you don't have to wait for all the packets in the buffer to be sent out (unlike the FIN packets above), and you directly send RST packets to discard the packets in the buffer. After receiving the RST packet, the receiving end does not need to send an ACK packet to confirm it.
