Cache method and device

Abstract

The invention provides a cache method, which includes the following steps: acquiring user downloading behavior data, and extracting URL address information and access time in the user downloading behavior data; performing statistics of URL address access times of the URL addresses accessed by users within a preset time based on the extracted URL address information and access time; selecting the URL addresses accessed by users the most frequently in the URL addresses accessed by users according to the statistical-based URL address access times as a hot issue list; downloading the content corresponding to the URL addresses in the hot issue list to a content cache server. Through the adoption of the method, the hot issue content can be confirmed by the great amount of downloading behaviors of users, and are cached only, so that unnecessary content storage is reduced, and the cache use ratio is improved.

Description

technical field [0001] The present invention relates to the field of file downloads, and more specifically, to a caching method and device for caching content accessed by hotspots. [0002] Background technique [0003] Currently, when a user downloads content via a browser, it is usually directly downloaded from a source URL address. In this case, once the network condition is unstable, especially when the URL points to a foreign country or a URL with a very long route, the content of the file has been deleted or the route is broken, the content download will not be completed. The downloading mentioned here is not limited to file downloading in a general sense, and may also include downloading any network data files such as web pages, pictures, and documents. [0004] In order to solve the above problems, a common improvement method is to cache content to the server and let users download it from the server, such as CDN technology. CDN technology is a caching technology....

Problems solved by technology

[0005] However, there is a flaw in this technique, that is, the content may only be accessed once, and will not be accessed again in the future, but it always occupies the cache storage space

Although expired content can be deleted using the expired deletion technology, the content still occupies the cache before the expiration. Therefore, judging from the huge amount of content on the network, a very large cache storage space is required for content caching , resulting in very large storage costs
