Here is a description of the four common settings that are supported by its upstream: Code highlighting produced by Actipro CodeHighlighter (freeware)

, because the consumption of system resources varies greatly by different applications, the number of connections cannot reflect the actual application load, therefore, when a heavy web server is used as a cluster node service (such as an Apache server), the algorithm will have a discount on the load balancing effect.

The hash Scheduling Algorithm Based on the target address can be used in the Web Cache cluster. All access requests directed to the same target site are sent to the same Cache service node by the Load balancer, to avoid the Cache update problem caused by missing pages.3.3 least connection methodIn the least connectio
