Address: http://blog.csdn.net/iloveqing/article/details/1544958 When a sesson starts, the servlet container will create an httpsession object to transfer these httpsession objects from the memory to the file system or database in some cases, load them into the memory when you need to access them. The two benefits of this solution are as follows: memory consumption is reduced, and session data can be recovered from the file system or database when the

Session Management When a sesson begins, the servlet container creates a HttpSession object, in some cases transferring the HttpSession objects from memory to the file system or the database, and loading them into memory when needed. The benefits of this are two points: saving memory consumption, and when the Web server fails, you can also restore session data fr

Sometimes we come across a larger project, and to make it easier to implement some of the features, we'll split the project into separate Web projects.But when we manage these projects, there is only one landing port, and then we take the session in other projects to verify the identity.View tomcat about HTTP Connector There is a emptysessionpath that explains the following:If set to True, the all paths for

1.SESSION generally not what you say this way of working, you open a browser, then open a, request the same URL, then one of the landing, the other one will never also login. Session and browser itself this program is linked, generally not through the IP and port to bind (if it is port and IP, browser closed session is not necessarily invalid, there is obviously

retention mechanism described in Tomcat.1. Achieving the basicThe implementation of the TOMCAT session cluster is to use multicast to share sessions in the cluster, similar to keepalived.

There are many articles on the web that enable memcached to share the session through MSM (memcached Session manager), but many are patchwork and misleading. There happened to be a place recently, so I'll summarize it.MSM supports two modes of TOMCAT6,TOMCAT7,TOMCAT8,MSM support: Sticky sessions (sticky session) and Non-sticky sessions (non-sticky
