Session information sharing method and sharing system

Abstract

The invention discloses a session information sharing method and sharing system. The method comprises the steps that a session central controller is erected between cluster application servers and a cache server group, and session information is stored in the cache server group; each cluster application server is configured so that the cluster application server is enabled to transfer an http request to the session central controller when the cluster application server receives the http request transmitted by a client side; the session central controller is configured so that the session central controller is enabled to manage the session information stored in the cache server group according to the http request transferred by the cluster application servers and manage transmission of the session information so as to realize sharing of the session information between the cluster application servers and the cache server group. According to the technical scheme, the session central controller is erected for unified management of the session information stored in the cache server group so as to ensure the consistency and the security of the session information in the session information sharing process.

Description

technical field [0001] The invention relates to the technical field of Internet communication, in particular to a session information sharing method and a sharing system. Background technique [0002] With the popularity of the Internet, the prevalence of B / S (Browser / Server, browser / server) systems and the large number of users brought by the B2C (Buisness to Custmoer, business-to-consumer) model, the design of a single server and a single application is impossible. To meet the required performance and function requirements, in order to meet the above requirements, the application server cluster mode has become an effective solution. [0003] Since the communication protocol between the browser and the server used by users is generally the HTTP protocol, the HTTP protocol is a stateless protocol, and stateless means that the protocol has no memory capability for transaction processing. The lack of state means that if subsequent processing needs to use previous information,...

Problems solved by technology

[0008] The disadvantage is: the stored data cannot be too much, and the safety factor is low

[0011] The disadvantages are: the performance drops sharply with the increase of servers, it is easy to cause broadcast storms, and the session data needs to be serialized, which will affect the performance; in addition, when the local multicast cache of an application is full, it is impossible to write new ones. Multicast messages, so that session synchronization cannot be completed

[0014] The disadvantage is that the program needs to be customized to complete the development of the operation of the business layer and the persistence layer. Since each request needs to read and write the database, the system overhead is relatively large

[0017] The disadvantages are: the program needs to be customized, which increases the workload, and the object data stored in the cache needs to be serialized, which is inefficient; and when the cache server is down, all sessions will be lost
