HTTP slow attack is to use the normal interaction mechanism of HTTP protocol to establish a connection with the target server first, and then keep the connection unreleased for a long time.

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.)
This class can meet the basic requirements, but if we put a class like this without thread safety protection into a multi-threaded environment, there will definitely be problems. How to solve them? The first thing we think of is adding the synchronized keyword to the getInstance method, as follows:
