Alternative services allow an origin serving an http:// or https:// resource to nominate additional (protocol, host, port) tuples that the client can choose to request the resource from instead of the origin when making subsequent requests. This can be used, for example, as a protocol upgrade mechanism, for connection pooling, or for load balancing.
