The following is an analysis of some examples that we need to pay attention to when applying singleton pattern in the development process.When an attacker sends an http get request, Slowly sending useless header fields, And never sends the "\ r\ n\ r\ n" end flag, This allows the connection to the web server to be occupied for a long time and ensures that the link is not broken by timeout. However, the number of concurrent connections that the server can handle is limited. If the attacker uses a large number of controlled hosts to send such incomplete requests and continues to occupy them, the connection resources will be exhausted (slowhttptest tool).
