Information Interaction System Based on Web Session Sharing

Abstract

The present invention provides an information exchange system based on web session sharing. The system comprises at least one client, a load balancing device, at least two web servers and a distributed buffer sub system. Each of the at least two web servers processes a received service request and creates and maintains a session which is associated with the rerecvied service request and transmits service response to a corresponding client, wherein the session information sharing between the at least two web servers is realized by the at least two web servers by means of the distributed buffer sub system. According to the information exchange system based on web session sharing, the session information sharing can be realized in the condition of not affecting the performance of the servers.

Description

technical field [0001] The present invention relates to an information interaction system, more specifically, an information interaction system based on web session sharing. Background technique [0002] At present, with the increasingly wide application of computers and networks and the increasing variety of businesses in different fields, the information interaction process based on the web is becoming more and more important. [0003] The web-based information interaction process is usually a web application based on the HTTP protocol, and the HTTP protocol is a stateless protocol, that is, each HTTP request is an independent individual, and it cannot remember the relevant information of the previous HTTP request. However, with the increasingly rich business requirements, it is often required to complete many independent HTTP requests as an independent transaction, which requires a series of HTTP requests under one transaction to have a memory function for each other, res...

However, when the web server adopts the cluster deployment method, the web application will be deployed on two or more servers, so when the user initiates a service request through the client, the service request will first be sent to the load balancing device In this method, the load balancing device distributes service requests to servers with lower loads according to predetermined rules, but this method will cause the following problem: during a session, some of the multiple service requests sent by the user in sequence may be blocked Received by server A, others may be received by server B, that is, the status recorded by server A may not be known to server B, and thus cause related services to be unavailable

[0005] However, the above existing technical solutions have the following problems: frequent broadcasting of session information will occupy a large amount of server memory and CPU computing resources. In other words, the more servers that synchronize session information, the more serious the server performance loss will be. , that is, the performance of the server will be significantly affected by
