However, this method has great limitations. XMLHttpRequest requests are usually used for asynchronous refresh of local pages in Ajax methods. Not all requests are suitable to be initiated by this class, and the pages obtained through this class of requests cannot be recorded by browsers, thus carrying out operations such as forward, backward, refresh and collection, which brings inconvenience to users. In addition, for legacy systems that do not have CSRF protection, to use this method to protect, to change all requests to XMLHttpRequest requests, this is almost to rewrite the entire website, which is undoubtedly unacceptable.2.

First of all, as users, we try our best to download APP from regular channels and surf the Internet in a civilized manner, and try our best not to make broilers. Secondly, as a service manufacturer, when the server is attacked by DDoS, we try our best to improve the processing capacity of the server. When the processing capacity of our server is greater than that of the attacker, these attacks are nothing to the server. Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.【节目介绍】
