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). A web server software such as iis nginx has been modified for this attack method, but web servers such as apache and dhttpd will still be attacked by slowloris.Although there are subclasses in java that implement the interfaces of the parent class, But I think javascript can be different from java, It is possible that the parent class in java is an empty class, Subclasses to implement the interface of the parent class, in javascript, I think the common code is completely written in the parent function.
