tomcat session management

Preface Reprint please indicate the source: http://blog.csdn.net/wlwlwlwl015/article/details/48160433 For Web sites or Web applications with high traffic, high concurrency, the most common solution is to use load balancing for server clusters, such as the more popular nginx+memcache+tomcat. After the cluster, for example, we have n Tomcat, the user may visit our website the first request to distribute und

The biggest difference between a session and a cookie is: 1. Save in different locationsThe session is stored in the server's memory, and the cookie is stored in the browser or client file;2. Different life cycleSession is an access-based process that records the start-to-finish of an access, when the browser or process is closed, the session "disappears", and t

A Tomcat profile:Tomcat server is a free development of the source code of the Web application server, is a lightweight application server, in small and medium-sized systems and concurrent access users are not widely used, is the first choice to develop and debug JSP programs. The main application scenario is to parse the dynamic program code (JAVA) JSP program to handle the Tomcat interfaceInstallation of

In the distributed multi-tomcat Web cluster environment, the first thing to solve is the session sharing problem, the general implementation ideas are:(1) Session replication: Session synchronization between multiple Tomcat, Tomcat
