SignalR Real-time Application Cookbook

Sending messages from the server

Now that we have a good idea about how PersistentConnection can be registered and then used in our applications, let's go deeper and start sending some data with it. As usual, in SignalR, we need a client and a server to establish a connection, and both parts can send and receive data. Here we'll see how a server can push messages to any connected client, and we'll analyze what a message looks like.

We already mentioned the fact that any communication from client to server could, of course, be performed using plain old HTTP, but pushing information from a server to any connected client without any specific client request for that data is not normally possible, and that's where SignalR really helps.
