This is the generic handler that provides the specific balancing strategy implemented by the balancer modules. Check the documentation for Balancers for information about the necessary parameters for any of these.

Other handlers provide balancing mechanisms. Those are the FastCGI and the SCGI handler. If you are not using any of those but want to distribute the load among several servers, this is the handler you should be using.

Currently it supports connection forwarding and balancing, so you can configure it to forward the connection to a series of intranet servers for example. The generic balancer will forward the whole request, totally preserving its integrity: same URL, same headers, same eveything. If you would require a more complex behavior you should probably be using the Rreverse Proxy handler.
