Overview

Adds a member to a load balancing group. It can be used with a <Proxy> container directive and can take any of the key-value pair parameters available to ProxyPass.

BalancerMember can be used outside of a <Proxy> container, and in this case the "balancerurl" (see Syntax below) is required and it corresponds to the URL of the balancer defined in the ProxyPass directive.

Trailing slashes should be typically removed from the URL of a BalancerMember.

loadfactor

One additional parameter available only to BalancerMember directives is "loadfactor". It is a number between 1 (default) and 100 that defines the weighted load to be applied to the member in question.

Syntax

BalancerMember [balancerurl] url [key=value [key=value ...]]

Example

ProxyPass "/example" "balancer://mycluster/"

<Proxy balancer://mycluster>
    BalancerMember http://node1
    BalancerMember http://node2
</Proxy>
