MAX_UPGRADE_BODY

The default largest message of the internal port: the default in-memory limit of the WebFlux codecs. The host sets its internal server's limits (messageLimit) from the public port's, so a command the public port takes is taken when forwarded too; the server takes a body of up to that size on the request that upgrades a connection to h2c as well (the channel opens each connection with a HEAD). A forward larger than the internal port takes is refused (me.ahoo.wow.runtime.cluster.Refusal.TOO_LARGE), and its sender runs it.
