Does Nginx support any sort of zeroconf in its proxying to upstream<br>
servers?  I would like to make the backend publish themselves via<br>
something like zeroconf.  Nginx should route traffic to them when they<br>
publish themselves as online, and nginx should remove them from this<br>
list when they publish themselves as offline.<br>
<br>
Does that currently exist in nginx?<br>
