Abstract

Embodiments of the invention provide a CDN server and a data caching method thereof. The method comprises the following steps: a CDN server receives a first hypertext transfer protocol HTTP request message, wherein the first HTTP request message is used to access the data in a target range in a first file; dividing the target range into at least two sub ranges, and determining target sub ranges in which the data is not cached in the CDN server among the at least two sub ranges; for each target sub range, generating an HTTP request message used to request data in the target sub range; sending the generated HTTP request messages to a CDN source station; and receiving an HTTP response message including the data in the target sub ranges sent by the CDN source station, and caching the data in the target sub ranges. The CDN server can cache data in fragments.

Description

technical field [0001] The embodiment of the present invention relates to the field of network communication, in particular to a CDN server and a method for caching data thereof. Background technique [0002] Content delivery network (Content Delivery Network, CDN) relies on the edge servers deployed in various places, through the central platform's load balancing, content distribution, scheduling and other functional modules, so that users can obtain the required content nearby, reduce network congestion, and improve user access response speed and hit rate. The key technology of CDN mainly includes content storage and distribution technology. [0003] A node in the CDN network is a CDN server, and these CDN servers are distributed in areas or networks where user access is relatively concentrated. When a user visits a website, the global load technology is used to direct the user's access to the nearest CDN server that works normally. When the CDN server caches the data ac...
