There are two physical hosts a and b running tomcat respectively. The operating environments are both window. Host a runs nginx, and redis is also installed on a. If redis session sharing is not used, you can log in to either machine individually, but After using redis to share, request a host, and load nginx again, the login interface will be repeated. In addition, running demo to test session sharing is no problem. Search for 302nginx solutions and add rewrite ^/(.*) http ://www.downcc.com/$1 permanent;At this time, if I request host a again192.168.1.62/czzf, it will get 404, and the browser address bar will jump to http: //127.0.0.1/czzf

    upstream czzf{
        server 127.0.0.1:8080;
        server 192.168.1.100:9038 max_fails=1 fail_timeout=30s;
    }
    
    server {
        listen       80;
        server_name  127.0.0.1;
        rewrite ^/(.*) http://127.0.0.1/ permanent;
