balancing devices, and the ability to handle seven layers is bound to be lower than the four-tier mode deployment.Second, the needs of the application scenario.The benefit of seven-tier application load is to make the whole network more " intelligent ". For example, access to a Web site user traffic, you can pass the request of the picture class to a specific image server through seven layers, and can use

Tomcat 1.1 drops 3) Integrate Apache and Nginx Preface:The last two articles describe how to install and deploy Tomcat. However, there is a problem. When Tomcat needs to process static pages, it is slow, at least not as good as Apache, so

other two are real Web servers that provide HTTP services externally, using only the default CentOS HTTP service, and no other Tomcat-like, Jexus services are installed.

Preface:At present, many Web applications, or Web interfaces, will be at the entrance of the server, using a server container to listen to the port, and then make request forwarding, such as Nginx Apache. Server containers are critical to the entire Web service, including the ability to manage service processes, perform proxies, pre-process requests, and load balance. The focus of today's discussion is to m

Session retention is one of the most common problems in load balancing and is a relatively complex issue.Session hold is sometimes called sticky session (Sticky Sessions).Before we introduce session-keeping techniques, we have to take some time to figure out the concepts: what is a connection (Connection), what is a session, and the difference between the two. In particular, if we are just talking about
