Abstract

The invention relates to a cache technology and provides a cache updating method and a cache updating device for overcoming the defects that the efficiency of the conventional cache technology is not high and the overall performance of a system may be reduced. The cache updating method comprises the following steps of: extracting an address of a page when receiving a page access request; searching the page in a local cache according to the address, reading the page and returning; for each page which is stored in a server cache, periodically detecting whether the page is required to be updated based on an updating period which corresponds to the updating frequency of the page; and when the page is required to be updated, updating the page and improving the updating frequency of the page. The invention also provides the cache updating device. The invention has the advantages that: the local cache and the server cache can be updated; an updating process comprises active updating and passive updating, so updating efficiency can be improved; and the overall influence of the updating process on system performance is reduced. Furthermore, the technical scheme provided by the invention is easy to implement and applicable to popularization.

Description

technical field [0001] The present invention relates to cache technology, and more specifically, to a cache update method and a cache update device. Background technique [0002] The emergence of browser caching technology has greatly improved the speed of Internet access. For example, when a user performs operations such as "forward" or "backward" in the browser, he is actually using caching technology to retrieve the web pages he has already visited. Since these visited webpages are already stored locally or on a cache server, the browser can quickly acquire and then display them to the user, thus providing a fast-access user experience. [0003] Generally speaking, the storage capacity of the browser cache is extremely limited. Therefore, when the expired web pages occupy too much cache space, it will inevitably cause the recently frequently accessed web pages not to be cached, which will cause the cache to become invalid and reduce the access speed. Therefore, there i...
