[0023] 3. For the mirror resources of some download websites, the same resource will have multiple mirror images, so the resource is the same but the hostname in the URL is different;
[0024] 4. The same resource may be published on different websites, resulting in different URLs

Embodiment Construction

[0058] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0059] refer to figure 2 In this embodiment, the method for optimizing Web cache back-to-origin includes the following steps:

[0060] Step S21, receiving the user's Web request;

[0061] Step S22, determining the file fingerprint vector of the resource according to at least part of the file content of the resource pointed to by the Web request;

[0062] Step S23, judging whether the resource is in the resource cache unit according to the file fingerprint vector;

[0063] Step S24, if yes, return the resource cached in the resource cache unit to the user.

[0064] Further, in step S21, the user's web request may be a regular web request, which may contain the URL of the requested resource.

[0065] In step S22, the file fingerprint vector of the resource can be dete...

Abstract

The invention provides a Wed cache and return optimization method and a Web cache system. The Wed cache and return optimization method comprises the steps of receiving a Web request of a user, determining the file fingerprint vector quantity of a resource according to at least part of file contents of the resource pointed by the Web request, judging whether the resource is in a resource cache unit according to the file fingerprint vector quantity; if the resource is in the resource cache unit, the resource cached in the source cache unit is returned to the user. According to the Wed cache and return optimization method and the Web cache system, the fact that one source cannot be repeatedly cached, the utilization efficiency of a cache node is improved, and bandwidth pressure is further reduced, and user experience is improved.

Description

technical field [0001] The invention relates to Web caching technology, in particular to a Web caching back-to-source optimization method based on intelligent resource differentiation and a Web caching system. Background technique [0002] Web cache (Web cache) is a caching system based on the HTTP protocol. The main function of the system is to cache static resources. When a user visits, it determines whether there is a resource requested by the user in the cache. If there is, the resource is returned to the user directly, otherwise The proxy user requests the resource from the origin site, returns it to the user, and judges whether the resource can be cached, and if so, caches it. The introduction of a Web caching system can play the following three roles: [0003] 1: Reduce the pressure on source site visits; [0004] 2: Reduce the outbound bandwidth of the source station and relieve the bandwidth pressure of the backbone network; [0005] 3: Since the cache system is ...
