The Slowloris attack exploits a vulnerability in the web server (or an unreasonable parameter configuration) and directly causes a denial of service. Slowloris is an attack method proposed by famous Web security expert RSnake in 2009. Its principle is to send HTTP requests to the server at a very low speed. Since the Web Server has a certain upper limit on the number of concurrent connections, if these connections are maliciously occupied and not released, all connections of the Web Server will be occupied by malicious connections, thus new requests cannot be accepted, resulting in denial of service.
The above is just a synchronous chain of responsibilities, We let each node function return a specific value "nextSuccessor" synchronously, To indicate whether to pass the request to the next node, we will often encounter AJAX asynchronous requests in our development. After the request is successful, we need to do something so-and-so. At this time, if we apply the above synchronous request again, it will not take effect. Let's understand and use asynchronous responsibility chain to solve this problem. We add another prototype method Chain.prototype.next to the Chain class to manually pass the request to the next node in the responsibility chain.
