loadbalancer

A basic TCP/UDP loadbalancer that can use round robin, hash, and least number of connections mechanisms for proxying to backends. Can also be used for TLS termination. See the sample_configs directory for sample configs.

The loadbalancers config is specified with the '-config' option and can be a path to file or a HTTP URL.
