Dynamic page cache method and system based on session

Abstract

The invention discloses a dynamic page cache method and system based on a session. According to the invention, the caching problem of a dynamic page capable of being logged in is solved, and the capability of caching the dynamic page capable of being logged in is enhanced while the CDN (content delivery network) service efficiency is not affected. The invention has the technical scheme that the method comprises the following steps of: comparing the request headers of HTTP (hyper text transport protocol) requests when a logged-in user and a non-logged-in user request a same website; obtaining the specific difference part of a website server, which is used for judging the user logging-in state; caching a page given by a source station when the user does not log in; according to whether the request header in the HTTP request of each user comprises the specific difference part, judging whether the user logs in or not; for the logged-in user, backing to the source to obtain a response and sending the response to the user; and for the non-logged-in user, responding by a cached page.

Description

technical field [0001] The invention relates to dynamic page caching technology, in particular to a dynamic page caching method and system of a content distribution network (CDN). Background technique [0002] Most websites include a user login system. For the same URL, the HTTP server may respond to different pages for logged-in and non-logged-in users. For example, when accessing the homepage, the login page is displayed for non-logged-in users, and the personal homepage is displayed for logged-in users. We call such pages dynamic pages that can be logged on. [0003] Current CDNs do not distinguish between loginable dynamic pages and other types of dynamic pages, either do not cache such pages, or use complex dynamic page caching techniques to cache all types of dynamic pages. Existing dynamic page caching technologies include: [0004] (1) ESI (Edge Side Include): By using markup language to describe the content fragments in the web page that can be accelerated and ca...

AI Technical Summary

Problems solved by technology

[0007] (1) If the dynamic pages that can be logged in are not cached, the acceleration effect of the CDN will be affected, especially under the trend of more and more dynamic web page applications, this impact will become greater and greater

[0008] (2) The use of ESI technology requires modifying the original HTML page on the source site to mark the cacheable and non-cacheable content, which is not practical for CDNs. On the one hand, CDN manufacturers do not have such authority; on the other hand, This requires modification of the page of the origin site, increasing the burden on CDN customers

[0009] (3) The dynamic page caching technology based on page analysis is very complex, and needs to analyze page content, which affects service efficiency and prolongs response time
