Embodiment Construction

[0036] In order to solve the above-mentioned problems existing in the prior art, the technical solution adopted in the embodiment of the present invention performs the corresponding data update task through the update server, and verifies the data in the cache server and the corresponding data stored in the source station server, so as to Update the data stored in the cache server according to the verification result instructions, instead of initiating a data verification request to the origin server every time a data acquisition request sent by the client is received, thus reducing operating overhead and saving resources .

[0037] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 A flow chart of a data updating method in an embodiment of the present invention is shown. see f...

Abstract

Provided are a caching server, an updating server and a data updating method. The data updating method comprises the steps of judging whether or not corresponding data stored in the caching server coincides with the corresponding data stored in a source station server when a data updating task is received; and when it is judged that the corresponding data stored in the caching server does not coincide with the corresponding data stored in the source station server, instructing the caching server to update the stored corresponding data. The above scheme can reduce the running cost and save the resources when updating of the data in the caching server is carried out.

Description

technical field [0001] The invention relates to the field of content distribution networks, in particular to a cache server, an update server and a data update method. Background technique [0002] Content Delivery Network (CDN), by placing caching servers all over the network, builds a layer of intelligent virtual network on the basis of the existing Internet, and publishes the content of the website to the "edge" of the network closest to the user. So that users can get the content they need nearby, so as to alleviate the network congestion and improve the response speed of the website. Technically, it fully solves the problem of slow response speed of users visiting websites due to reasons such as small network bandwidth, large number of user visits, and uneven distribution of outlets. [0003] In order to keep the data stored in the cache server consistent with the corresponding data in the corresponding origin server, the Hyper Text Transfer Protocol (Hyper Text Transf...
