METHOD OF COPYING HTTP SESSION BY COOKIE AND VERSION NUMBER IN CLUSTERED WEB APPLICATION SERVER

摘要

The invention relates to a method for performing the HTTP session replication efficiently between the application server nodes using the HTTP session identifier and the version information in the clustered web application server environment. This invention is in the generation, but transmits the HTTP session created during a session ID, generates a session version, using the HTTP session created or changed by a multicast protocol, the session information, a session identifier, session version information on any Web application server other after you say only send commands only, without waiting until the transfer is completed, the waiting time during the time of completion of transmission, change and return the results. And the result returned upon return stores the session identifier, the version number in the cookie, and when the future load distributor forwards the request to the client to another Web application server, the web application server extracts a session identifier and version number in the cookie that HTTP session exists in its own session storage, if is newer than the HTTP session version extracted from cookies using the HTTP session, otherwise receives the HTTP session information within a certain period of time through a multicast protocol, it received the HTTP session It uses.
