## Balancer: Round Robin

If multiple server entries are defined, the requests will be round-robinly served by each of them.

The configurable parameters will vary depending on what has been selected as information host. If it is set to remote, only a host address will be required. If that is not the case then configurable parameters will be:

- Host: Either a local or remote host and port.

- Interpreter: Defines the command line of the interpreter for this server. If you are using FastCGI or SCGI and are launching the services manually, this entry is not needed.

- Environment variables: When running in local host, you can set up environment variables to be used by whatever is serving your load-balanced requests.
