Three protected web resources, where each has a weight of 1, have an equal number of requests routed to each of them.

Two protected web resources, that have weights 1 and 2, have twice as many requests (or 66% of the total number of requests) routed to the hostname with a weight of 2, compared to the hostname with a weight of 1.

Health checks

Health checks are used to determine if a back end protected web resource can service requests.

The load balancer edit health check dialog showing default values.

Protected web resources can be in one of three states:



Active Initial state, host entered and active but health unknown.

When health checks are disabled, protected web resources never leave this state.

Healthy Host is responding based on health check settings.
Unhealthy Host isn't responding; new requests won't be routed to it.
