Abstract

The application discloses a picture preloading method and a picture preloading device. The method comprises the following steps: receiving the network address and target identifier of a to-be-preloaded picture on a content delivery network, wherein the target identifier is the service provider identifier of the content delivery network; extracting a network domain name from the network address of the to-be-preloaded picture; acquiring an IP address corresponding to the network domain name from a preset database, wherein different network domain names correspond to different IP addresses; and associating the network domain name with the IP address corresponding to the network domain name. According to the application, the technical problem that a mobile terminal cannot preload a picture is solved.

Description

technical field [0001] The present application relates to the field of data processing, and in particular, to a method and device for preloading images. Background technique [0002] CDN (Content Delivery Network) is a content distribution network. It uses distributed caching node services to achieve the purpose of optimizing the access speed of netizens in different regions. Preloading is a common way to optimize the speed of CDN access resources. Before, let the CDN node pre-cache the URL. The way of preloading is to centrally use different browsers to send requests to CDN nodes to download the URLs that need to be preloaded before Internet users send out visits. Different browsers and client UA (User Agent) may need to be preloaded separately. For example, after using the Firefox browser of the PC to access a picture to the node, the picture will be accessed by other PCs using the Firefox browser. It will be in the hit state, that is, the cache is hit, and there is no n...
