Example

For an example of distributing peer lookup requests across multiple servers, see Distribute peer lookup requests across

multiple servers.

See also

application.sendPeerRedirect(), Client.introducePeer()

application.onPublish()

application.onPublish = function (clientObj, streamObj){}

Invoked when a client publishes a stream to an application. Use this event handler to send traffic to other servers when

you’re building a large-scale live broadcasting application; this is called multipoint publishing. For example, you can

support subscribers in multiple geographic locations by sending traffic from the origin server (Server A) in one city to

two origin servers in two different cities (Server B and Server C). The following is the workflow for such a scenario:

1 A client publisher connects to Server A and starts publishing.

2 Server A receives notifications from the event handler application.onPublish() in a server-side script.

3 Inside the onPublish() handler, create two NetStream objects to Server B and Server C.

4 Call the NetStream.publish() method to redirect the publishing data from Server A to Server B and Server C.

5 Subscribers connecting to Server B and Server C get the same live stream.

In this example, the publishing client connects and publishes only to Server A. The rest of the data flow is handled by

logic in the server-side script.

Note: You cannot change Client object properties in this handler.
