Question

SSE vs flush js?

One of the signalR backup signals is events sent by the SSE server. which all he does is send a message through this structure:

Message\n\n

therefore, on the server side:

Response.ContentType = "text/event-stream";

while (startDate.AddMinutes(1) > DateTime.Now)
{
    Response.Write(string.Format("data: {0}\n\n", DateTime.Now.ToString()));
    Response.Flush();

    System.Threading.Thread.Sleep(1000);
}

big.

but not so much.

I could easily use a JS command with data (e.g. jsonp does aka: padding with a callback analogy), for example: _ cb(myMessage)

And on the client side - treat it like that. (even with the more acclaimed mime type like application / javascript)

I probably missed something.

What is the advantage of SSE?
