Session is a conversation scope, the application is the application scope, if you want to use the application at all to see the counter just a session if the count results using the session

CodePudding user response:

An application is only one application scope, all men to access application is within the scope of value, example: website domain name, the name

Multiple requests (before the session not expired) share the same session scope. Example: I visit your web site and access for the first time the server will assign a session for me, I'm from one page to another page, as long as I use within the validity period of the session is the same session, the session default is 30 minutes, you can set it to less than 30 or more than 30

CodePudding user response:

Since the session only exists in the server, so there is a problem in the cluster, how to share it between the clusters, of course, there are solutions, set up: you have three servers to form a cluster, when I visit a connection request from the cluster the SRV - 01, I from a link to jump to b, but b connection is accepted by the SRV - 03,

So think of the future may change from one server to a cluster, the program design in general is not in session now preserved value, can use a cookie, or by the middle of the certification authority to take over, you can also use the redis this memory libraries
