Method and system for updating browser cache

Abstract

A method for updating a browser cache comprises the steps of receiving a request for page opening, and pulling a configuration file of a page from a server, wherein identifications of resource files of the page, which are required to be cached, and modification timestamps of resource files are recorded in the configuration file of the page; comparing the pulled configuration file with a local configuration file to obtain the identification of the resource file, which is required by updating of the browser cache; and updating the corresponding resource file in the browser cache according to the obtained identification of the resource file. According to the method for updating the browser cache, when the cache is required to be updated, only the resource file which is required to be updated is required to be downloaded, but not all the resource files of the page, which are to be cached, are required to be downloaded, so that the updating efficiency of the browser cache is improved. Besides, the invention provides a system for updating the browser cache.

Description

【Technical field】 [0001] The invention relates to the field of network technology, in particular to a browser cache update method and system. 【Background technique】 [0002] The resource files of web pages include resource files that need to be updated in real time and resource files that are not frequently updated. When the browser opens a web page every time, it needs to download resource files that need to be updated in real time from the server. , they can be stored in the browser cache for use when the browser opens the page next time, so that the loading of the page can be accelerated. [0003] In order to keep the latest data in the browser cache, the browser cache needs to be updated before loading the resource files in the browser cache. Specifically, the browser first asks the server whether the resource file to be cached on the page has been modified. If not, it directly loads the resource file in the local browser cache and displays the page; otherwise, download...

AI Technical Summary

Problems solved by technology

[0004] However, in this traditional browser cache update method, as long as the resource files that need to be cached on the page are updated, all resource files that need to be cached on the page need to be downloaded again, and if a resource file makes an error during the update process, the browser will It will think that the entire update process is wrong, and all the resource files that need to be cached will be downloaded again when the page is opened next time, resulting in inefficient browser cache update
