Problems solved by technology

[0005] When the DNS server is attacked, if the attacked domain name needs to be redirected for access, a large number of forwarding and parsing requests will be collected to the redirecting server, causing the forwarding server to be attacked by a large amount of traffic, making it unusable
[0006] At present, the forwarding server has a hard limit on the flow of access. If the flow limit is exceeded, the access will be restricted, even normal access will be restricted, the error rate is high, and the efficiency is very low.

Embodiment Construction

[0082] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0083] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for processing an access request of the present application, which may specifically include the following steps:

[0084] Step 101, when the DNS server receives the access request from the client, it forwards the client's access request to the first redirect server for redirect access;

[0085] Applying the embodiment of this application, a first jump server (also known as URL (Uniform Resource Locator, Uniform Resource Locator, Uniform Resource Locator) forwarding server) can be added in the DNS server for a certain source address (host name or domain name). The address record data of the forwarding address (su...

Abstract

The embodiment of the present application provides a method and device for processing an access request, the method includes: when the DNS server receives the access request from the client, forwards the client's access request to the first redirect server for redirect access; The server receives the notification message sent by the first jump server when judging the abnormal access; the DNS server forwards the client's access request to the second jump server for traffic cleaning according to the notification message. The embodiment of the present application provides defense against individual access, and while ensuring the security of the first jump server, it also ensures that other normal accesses are not affected, reduces error rates, and improves efficiency.

Description

technical field [0001] The present application relates to the technical field of computer processing, in particular to a processing method for access requests and a processing device for access requests. Background technique [0002] In the Internet, each IP (Internet Protocol, protocol for interconnection between networks) address can have a host name. [0003] DNS (Domain Name System, Domain Name System), as a distributed database that maps domain names and IP addresses to each other, finally resolves the host name to obtain the corresponding IP address of the host name, which can make it easier for users to access the Internet. An intuitive and meaningful domain name is enough, instead of remembering the IP address that can be directly read by the machine. [0004] In some cases, the DNS server will be configured with a jump server, and through the special settings of the server, the user currently accessing the domain name will be directed to another specified network a...
