Cloud-based file duplicate-removing method

Abstract

The invention discloses a cloud-based file duplicate-removing method. According to the method, different HTTP cache acceleration devices are adopted to upload corresponding records of URLs stored by the HTTP cache acceleration devices and file content; the cloud integrates the records uploaded by all the devices and issues the records to each HTTP cache acceleration device; after obtaining the records provided by the cloud, the HTTP cache acceleration devices read corresponding relations between the URLs and the file content; and therefore, when a user visits an URL in a local area network, an acceleration function can be provided.

Description

Technical field [0001] The invention relates to a cloud-based file deduplication method, which belongs to the field of network technology. Background technique [0002] HTTP cache acceleration is a method of accelerating access to Internet resources in a local area network by localizing Internet resources, and caching the Internet with high bandwidth. The principle of this method is to listen to repeated URL requests in the local area network. If the request for the same URL reaches a certain number of times, the resource pointed to by the URL is downloaded to the local area. When there is the same URL request in the local area network, the 302 in the HTTP protocol is used. Redirection response, redirect the external network request in the LAN to the internal network. [0003] However, there are two phenomena in the prior art: First, in the current network environment, due to users' high requirements for website access speed, most websites will use CDN nodes for acceleration. The...

Problems solved by technology

[0006] However, the disadvantage of this typical solution is that the HTTP cache acceleration device can know the correspondence between the URL and the file only after the LAN user has accessed the URL
