Embodiment Construction

[0017] see figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the picture caching method of the present invention.

[0018] The picture caching method in this embodiment includes the following steps:

[0019] Step 101, periodically acquire pictures to be displayed on the website within a preset period of time.

[0020] Step 102, assigning a cache address of a CDN cache server to the acquired picture according to the identification information of the acquired picture, and cache the acquired picture to the CDN cache server according to the allocated cache address.

[0021] The picture caching method described in this embodiment automatically and periodically acquires pictures to be displayed on the website within a preset period of time, and caches the acquired pictures to the CDN cache server. The cache control is more flexible, and the content to be displayed on the website can be cached in advance. When a large number of users suddenly visit the web...

Abstract

The invention discloses a picture caching method and a picture caching system. The picture caching method includes periodically acquiring to-be-displayed pictures of a website within a preset period, distributing caching addresses of a CDN (content delivery network) caching server to the acquired pictures according to identification information of the acquired pictures, and caching the acquired pictures to the CDN caching server according to the distributed caching addresses. According to the picture caching method and the picture caching system, the to-be-displayed pictures in the website within the preset period is acquired automatically and periodically, and the acquired pictures are cached to the CDN caching server, so that caching control is more flexible; to-be-displayed content of the website can be cached in advance, so that when a large number of users visit the website suddenly, accessing pressure of the website can be effectively reduced, and 'source return' pressure of a picture source website can be effectively avoided.

Description

technical field [0001] The invention relates to website picture browsing technology, in particular to a picture caching method and system. Background technique [0002] With the development of Internet technology, more and more websites transmit information to users through pictures. Each website generally caches the picture data to be displayed in the CDN (Content Delivery Network, Content Delivery Network), so that the picture links on the website use the caching service link, and set the link relationship between the CDN and the image source file. When the user visits, click on the picture link, if there is a corresponding picture cached in the CDN, the content of the picture will be returned directly, which can divert the traffic and reduce the pressure on the main site; if there is no corresponding picture cached in the CDN, the CDN will access the corresponding picture source file And store the corresponding picture data in the cache, set a certain expiration time in ...
