Embodiment Construction

[0042] In order to make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below based on the drawings and specific implementation methods.

[0043] This application intercepts the client's request on the application server, comprehensively obtains the information of each user according to the request, and filters the client's request through the blacklist mechanism, in order to solve the problem of huge amount of data generated in a short period of time due to web crawlers or malicious attacks. While accessing the network, it can reduce the overhead of the server system, filter the requests of the client more accurately, and reduce the error filtering of the normal access client; according to the comprehensive acquisition ability of user information, the filtering can be adjusted according to different actual situations User information combination, flexible configur...

Abstract

The invention provides a flow control method and a flow control device, and relates to the technical field of networks. The method comprises a first step of intercepting a request of a user side at an application server terminal, a second step of obtaining a user information combination according to the request, and a third step of matching the user information combination with a user information combination in a blacklist. If the user information combination is matched with the user information combination in the blacklist, the user information combination is filtered. The blacklist is generated through the following steps: a first step of counting visit times of the user information combination corresponding to the user request according to a recording log of the user information combination corresponding to the request, and a second step of generating the blacklist of the user information combination according to the visit times and a flow control rule. According to the flow control method and the flow control device, when the problem that a huge amount of network access is produced in a short time caused by due to web spiders or hostile attack is solved, system overhead of a server system is reduced, the request from the user side can be accurately filtered, and the times of false filtering of normal access to the user side are reduced. The flow control device is flexible in configuration, wide in application range and capable of effectively improving the filtering efficiency of the system.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a flow control method and device. Background technique [0002] With the widespread use of computers, there are more and more frequent visits to application servers in the network. However, there may be visits caused by web crawlers or malicious attacks in the visits to application servers. Access can easily exhaust the system resources of the application server and cause the application server to become unstable. [0003] In the prior art, the request is intercepted when the request from the client does not reach the application server, and the IP address information in the request is generally captured and analyzed to confirm that the request belongs to the client. If the user corresponding to the same IP address is analyzed If the request access frequency is too high in a short period of time, the user request corresponding to the IP address will be filtered. Beca...
