What’s good as well is that if you start your Phoenix server based on this channel code and open in two browser tabs, you’ll see that the changes you make in one tab get the other one instantly updated. Well, not exactly, since these real-time updates are based on the fact that we have a single Phoenix server acting as a hub for all our changes and having all the clients listening to the same topic.This operation is expected to be infrequent; it occurs only when the . All Windows 2000 Server–based domain controllers that are running an RFC 1510–compliant Kerberos KDC service register this SRV record.
