, writing, expiration, and synchronization. The third is to maintain sessions on the same server through the nginx ip_hash load, which looks the most convenient and lightweight. Under normal circumstances, if the architecture is simple, ip_hash can solve the session problem, but let's take a look at the following situation: At this time, all requests received by ip_hash come from a fixed IP proxy.

Core Tip: Goal: To use Apache and tomcat to configure a Web site that can be applied, to meet the following requirements: 1. Use Apache as the httpserver and connect multiple Tomcat application instances, and load balancing. 2. Set the Session Timeout time for the system, including Apache and tomcat 3. List of blocked files for the system, including Objectives:To use Apache and tomcat to configure a Web site that can be applied, you must meet the foll

consumption. First, the configuration is very simple and powerful. It's time to see each other. Let's take a look at how to write the configuration file. Copy codeThe Code is as follows: worker_processes 1; Events { Worker_connections 1024; } Http { Upstream myproject { # Multiple source servers, ip: Port, and port 80 can be written or not Server 192.168.43.158: 80; Server 192.168.41.167; } Server { Listen 8080; Location /{ Proxy_pass http: // myproj
