my requirements were met by configuring URL rewrite rules. Assuming that the ARR server provides external services on port 80, after receiving the port 80 request, the server Load balancer will also forward requests to Web applications on port 8080 to process requests or Web applications on port 8080 of other services. General steps 1. Add the ARR server to serv

Introduction to load Balancing clusters The software that realizes load Balancing cluster is: LVS, keepalived, Nginx, Haproxy and so on. The LVS belong to four layer (network OSI model), Nginx belongs to seven layer, haproxy can be considered as four layer, also can be used as seven layer. The Keepalived load balancing function is actually the LVS
