Embodiment Construction

[0049] 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.

[0050] refer to figure 1 , showing an application architecture diagram of a system implementing cache update and providing update resources of the present application. The system providing update resources includes background server and foreground server. The front-end server adds identification parameters to the url and / or resource description file (manifest file) of the changed resource file according to the real-time information transmitted by the back-end server, and then transmits the url and / or resource description file with the identification parameters to the client , so that the client can judge whether to update the cache by comparing it with the url in the cached offline resources, so as to r...

Abstract

The invention provides a cache updating method comprising the following steps: when offline resources of a webpage are cached, identification parameters of resource files are stored; the identification parameter of the current resource file of the webpage is acquired from a server end; the identification parameter of the current resource file and the identification parameter of the cached resource file of the webpage are compared; and if the identification parameter of the current resource file and the identification parameter of the cached resource file of the webpage are different, the current resource file acts as the offline resource of the webpage to perform caching and updating. The invention also provides a cache updating system for realizing the aforementioned method, and an update resource providing method and system. According to the cache updating method and system, and the update resource providing method and system, the client terminal cache can be timely updated.

Description

technical field [0001] The present application relates to the technical field of computer data processing, in particular to a cache update method, a method and a system for providing update resources. Background technique [0002] With the continuous development of network technology, webpages of the fifth generation hypertext markup language (html5) specification are gradually replacing the webpages of the previous generation, that is, the fourth generation hypertext markup language (html4) specification. The fifth-generation hypertext markup language provides a caching function of application programs, allowing users to browse cached web pages or operate cached network applications in an offline state. [0003] In order to ensure normal browsing of web pages in an offline state, it is necessary to update the contents of the cache in real time in a networked state. The web page of the fifth generation hypertext markup language specification implements the update of the cac...
