Method, system and device for sharing session data

Abstract

The invention discloses a method for sharing session data. The method includes the first step of judging whether request content in a request message is a write operation request or a read operation request when any Web server in a Web server cluster detects that the Web server itself receives the request message, the second step of updating session fields according to the request message if the request content is the write operation request, and then sending the updated session fields to a session storage server, and the third step of extracting the corresponding session fields from the session data according to the request message if the request content is the read operation request, and then sending the corresponding session fields to corresponding clients. Meanwhile, the invention further discloses a system and device for sharing the session data. By the adoption of the method, system and device for sharing the session data, the sharing efficiency for the session data of the Web server cluster is improved, and moreover configuration of the Web server cluster is not increased.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method, system and device for sharing session (Session) data. Background technique [0002] When a user uses a client to access any website, the client establishes a connection with any Web server in the network (Web) server cluster of the website, and the information saved in the Web server is from establishing a connection to disconnecting the client. All information generated during the period of opening the connection is a session (Session). The Session includes two parts, a Session variable and a Session identification number (ID, Identity), wherein the Session variable is stored in the Web server, and the Session ID is stored in the client. Described Web server preserves the Session with client and comprises: after Web server receives the request that client sends to start session, generates the Session ID corresponding to this session, and Session ID is sen...

Problems solved by technology

[0004] However, in the above-mentioned method for sharing session data, since the data in the session sent by each web server in the web server cluster needs to be copied to other web servers, the session data is easily transmitted interactively in a network in the web server cluster. This will make the session data sharing less efficient; in addition, each web server in the web server cluster needs to know the location of other web servers, so that the configuration of the web server cluster is more complicated

[0005] It can be seen that the existing method for sharing session data requires all the web servers in the web server cluster to participate in session data sharing, resulting in low efficiency of sharing session data by the web server cluster, and the configuration of the web server cluster is relatively complicated
